Subject: [wxruby-users] Compiling wxRuby on Ubuntu 10.04
Message-ID: <4CAB5670.1000809@gmx.net>

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi there,

A few days ago I compiled wxRuby on Ubuntu 10.04 Lucid Lynx and came
over some issues not mentioned at
http://wxruby.rubyforge.org/wiki/wiki.pl?BuildingOnTopOfLinuxDistroPackages

First and most importantly, even though I though I had all necessary
packages installed, I was presented many errors about ld not finding
lgtk-x11-2.0 and other important libs as pango. I figured out that for
whatever reason, these files didn't exist on my Ubuntu installation:

/usr/lib/libgtk-x11-2.0.so
/usr/lib/libgdk-x11-2.0.so
/usr/lib/libatk-1.0.so
/usr/lib/libgdk_pixbuf-2.0.so
/usr/lib/libpangoxft-1.0.so
/usr/lib/libpangox-1.0.so
/usr/lib/libpango-1.0.so

Searching for similar named files turned up that I had files ending in
".so.0" in the /usr/lib/ directory. I'm not sure if I was correct in
doing so, but I just symlinked them to the needed file names:

/usr/lib/libgtk-x11-2.0.so.0 -> /usr/lib/libgtk-x11-2.0.so
/usr/lib/libgdk-x11-2.0.so.0 -> /usr/lib/libgdk-x11-2.0.so
/usr/lib/libatk-1.0.so.0 -> /usr/lib/libatk-1.0.so
/usr/lib/libgdk_pixbuf-2.0.so.0 -> /usr/lib/libgdk_pixbuf-2.0.so
/usr/lib/libpangoxft-1.0.so -> /usr/lib/libpangoxft-1.0.so
/usr/lib/libpangox-1.0.so.0 -> /usr/lib/libpangox-1.0.so
/usr/lib/libpango-1.0.so.0 -> /usr/lib/libpango-1.0.so

After figuering this out, the compilation process complained about
missing gl, glu and glut headers which I thought were optional. Maybe I
missed some compile option to ommit them and if so I'd appreciate it if
someone could enlighten me about that, but installing the freeglut3-dev
package did the trick for me.
I'm not sure about the StyledTextCtrl's dependencies--maybe I just have
the necessary headers on my system as I tend to install many development
packages on compiling problems (not only with wxRuby). Does wxRuby
complain on compilation if they're missing?

In short here are my questions:

* What's about that wrongly named shared object files? Is something
wrong with my system?
* How to instruct rake not to build gl, glu, glut and the
StyledTextControl extensions if the necessary development headers are
not available for whatever reason?
* What are the development headers needed for StyledTextCtrl?

Ah, and last but not least, why is the
http://wxruby.rubyforge.org/wiki/wiki.pl?BuildingOnTopOfLinuxDistroPackages
page not linked anywhere on the wxRuby homepage? It is only findable by
searching for it. There should be a link to it on
http://wxruby.rubyforge.org/wiki/wiki.pl?InstallingFromSource I suggest.

First off, doing the symlink is the correct procedure.  I found that from
Ubuntu 9.04 onwards, they stop putting the symlinks in for the libraries,
and therefore when trying to compile, it fails.  Symlinking was the correct
procedure here to compile.

StyledTextControl by default should be detected on weither it's installed or
compiled or not into the wxWidgets library, if it isn't compiled, then Rake
should detect that, and not attempt to compile StyledTextControl.  If you
want StyledTextControl, then you need to ensure StyledTextControl is either
installed (I believe it should be by default with the Ubuntu repository
packages), or going into contrib/stc/ and running make + make install to
build and install StyledTextControl.

As for gl/glu/glut ignore, I believe that you need to do something like
this: EXCLUDED_CLASSES=GLCanvas rake

This basically tells Rake, to ignore GLCanvas.  I could be wrong, as I've
never tried to compile wxRuby without GL, even though I don't use it
personally myself.


> * What are the development headers needed for StyledTextCtrl?
>

There shouldn't be any dependancies you need to install for StyledTextCtrl,
as it's generally compiled into the wxWidgets library, if you build
yourself, you would need to go into contrib/stc/ and run make/make install
to build the STC code, and wxRuby will automatically detect if it is there,
or not, and compile  based upon the detection of it being there for you.

Ah, and last but not least, why is the

I didn't even know that page was there, someone probably added it last year,
and forgot to make the necessary changes.  The Wiki is in pretty bad shape,
and needs to be fixed.

I was wrong. You're right Alex,

it is possible to update grid with @grid.refresh
I rewrite my gridtablebase object and now it can handle @grid.refresh

here is my code

require 'rubygems'
require 'wx'

class Dataset_h < Wx::GridTableBase
    def initialize(par={})
        super()
        if par[:colnames]     then @colnames = par[:colnames] else @colnames
= [] end
        if par[:keys]         then @keys = par[:keys]         else @keys =
[]     end
        if par[:rs]         then set_rs(par[:rs])             else @rs =
[]        end

        @display_data = @rs
        @rows = @display_data.size
        @cols = @keys.size
    end

    def get_number_rows
        @rows
    rescue
        0
    end

    def get_number_cols
        @cols
    rescue
        0
    end
    def get_value(row, col)
        ((@display_data[row])[@keys[col].to_sym]).to_s
    rescue
        ""
    end

    def get_attr(row, col, attr_kind)
        Wx::GridCellAttr.new
    end

    def is_empty_cell(row, col)
        true
    end

    def get_col_label_value(col)
        @colnames[col]
    rescue
        ""
    end

    def set_keys(keys=[])
        @keys = keys
    end

    def set_rs(rs)
        @rs = []
        rs.each do |key, value|
            @rs << value
        end
    end

    def auto_rs(rs)
        set_rs(rs)
        @display_data = @rs
        @keys = rs.keys

        @colnames = []
        @keys.each do |key|
            @colnames << key.gsub('_', ' ').capitalize
        end
    end

    def filter(par)
        tmp = []
        @rs.each do |row|
            par.each do |key, value|
                if row[key.to_sym] == value
                    tmp << row
                end
            end
        end

        @display_data = tmp.uniq
        @rows =  @display_data.size
    end

    def filter_like(par)
        tmp = []
        @rs.each do |row|
            par.each do |key, value|
                if row[key.to_sym].to_s.index(value)
                    tmp << row
                end
            end
        end

        @display_data = tmp.uniq
        @rows =  @display_data.size
    end

    def add(data)
        @rs << data
    end

    def delete(row)
        @rs[row] = nil
        @rs.compact
    end

    def all
        @display_data = @rs
    end

    def first
        @display_data.first
    end

    def last
        @display_data.last
    end
end

but then I found another problem
I want this object to be a memory storage, where I can add, update, or
delete and filter rows.

but when I modify data in gridtablebase object, grid is updated, but not
quite perfectly
the grid does not update its row number (and perhaps col number, I have not
tried that)
so when I filtered, there is empty row below last row

even worse when I add data, if gridtablebase data row counts more than grid
row
grid will not append rows

is there a way to handle this? since this is so close to what I need,
I really hope there is a way to handle this problem

Thank you

For some reason the evt_media_loaded is not being triggered on windows 7
and windows vista. However, the same code on windows xp works just fine.
Anybody have any ideas?

and windows vista. However, the same code on windows xp works just fine.
Anybody have any ideas? What I'm trying to do is auto play audio once it 
has loaded. My solution right now has been to just user a static timer 
and hope that the audio loads within that time. Once the timer counts 
down it will try to play the audio. However, if the audio is not done 
loading it will not work correctly

It appears to be a bug in wxWidgets:
http://trac.wxwidgets.org/ticket/10958

We will have to wait for a fix in the underlying library - I don't have 
Windows 7 so unfortunately I can't look into it myself.

There is some discussion on this page - but it sounds like the final 
workaround is similar, ie call sleep(1) after load.

Hello Misha,

First off, welcome to wxRuby community.  I'll answer your other question in
a few, first we'll cover this one.

First off, this is correct in the code, till you get to your on_init method.
 I can tell you, that your Window is being created, and everything, but your
not showing it to the user.  There's two ways in which you can do this.

The first, is to simply do: MyFrame.new.show()  Which will show your frame
to the user, after it is created.
The second, is to store the instance of your Window in a variable, and call
show in it, like this:
myframe = MyFrame.new
myframe.show

In both cases, you need to call the show method on your Frame, in order to
have your frame actually be displayed.  It isn't done automatically, cause
there may be times, where you want to create a window, but not show it, in
such cases as having a Tray Icon on Windows / Linux, and a Dock Icon on OS X
(EG The Bottom bar.)

hth with this one,

Mario

1.jpg) This is the cause of the fact that in your XRC Design, you do not
have a root Layout manager, meaning that the window needs to have a
VerticalSizer or a HorizontalSizer as the root item, in order to manage
layouts of all the controls in your window, otherwise, you have to do the
management of the layout yourself, meaning you need to keep tabs on the
window sizes, and control positions, and re-positioning your controls
yourself.  This also means that wxWidgets will not manage the window size,
and therefore, will allocate the minimal size for your window, which gives
you the issues you are seeing in 1.jpg.

This is an issue with Ruby 1.9.1, they made String where it is no longer
Enumerable, meaning that there is no .each method, that will parse through
each actual line of text in the code, as is done in Ruby 1.8.  I will see
about getting a new gem built, with a patch to fix that soon.

Hi Rob,
I have the same problem with a ListCtrl Object,
and the solution for me is to REFRESH the ListCtrl after the selection:

 >    ListCtrl#set_item_state( )
 >   ListCtrl#refresh_items( )

I hope it helps

Thanks. Now I'm a new wx'er.

BTW, Misha on russian equivalent Michael in english :)

How you do the letters green?

1) I create forms now in DialogBlocks 4.39 (next - DB). If I do not 
create a menubar, it's OK. If I add it, I need to change a PLATFORM 
value on it from any to some. It's normal?

2) Conversion is normal in DB - in my opinion, the question is closed.

3) I copy code, but it not works:

------

require 'wx'
include Wx

class MyFrame < Frame
  def initialize()
        super(nil, -1, 'My Frame Title')
        # First create the controls
        @my_panel = Panel.new(self)
        @my_label = StaticText.new(@my_panel, -1, 'My Label Text', 
DEFAULT_POSITION, DEFAULT_SIZE, ALIGN_CENTER)
        @my_textbox = TextCtrl.new(@my_panel, -1, 'Default Textbox 
Value')
        @my_combo = ComboBox.new(@my_panel, -1, 'Default Combo Text', 
DEFAULT_POSITION, DEFAULT_SIZE, ['Item 1', 'Item 2', 'Item 3'])
        @my_button = Button.new(@my_panel, -1, 'My Button Text')
        # Bind controls to functions
        evt_button(@my_button.get_id()) { |event| 
my_button_click(event)}
        # Now do the layout
        @my_panel_sizer = BoxSizer.new(VERTICAL)
        @my_panel.set_sizer(@my_panel_sizer)
        @my_panel_sizer.add(@my_label, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_textbox, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_combo, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_button, 0, GROW|ALL, 2)
        show()
    end

    def my_button_click(event)
        # Your code here
    end

end

class MyApp < App
  def on_init
    MyFrame.new
  end
end

MyApp.new.main_loop()

myframe = MyFrame.new.show()

---------

There isn't a .xrc file in this folder. It's only .rb file. It doesn't 
work...

Can you give me some working simple window code to Copy-Paste in .rb 
file as example of ruby-GUI-application.

Sorry for my english, Misha.

Message-ID: <c81b33f35ee49559162f9b09f83e5051@ruby-forum.com>

Hi,

  I am trying to register a global hotkey using wxruby on Windows XP
SP3. The documentation at
http://wxruby.rubyforge.org/doc/window.html#Window_registerhotkey says
that register_hot_key is available (although I don't quite understand
the comment there about Windows CE).

Anyway, here is the smallest piece of code I could come up with for
reproducing the problem:

require 'wx'
frame = Wx::Frame.new
frame.register_hot_key(100, Wx::MOD_ALT, Wx::K_F1)

=> NoMethodError: undefined method `register_hot_key' for
#<Wx::Frame:0x38bfd70>

Wx::Frame inherits from Wx::Window, so I would expect that method to be
there.

Any ideas on why this doesn not work? Am I doing something wrong?

I am using wxruby (2.0.1 x86-mingw32).

Fine regards

Nicholas

Run it in a command prompt and *post the error message*, then we can 
help. There is a sample called 'minimal.rb' in the distribution that you 
can use as a basis for testing and the starting point for your own apps.

Hi there,

Three days ago I updated my Ubuntu Lucid to a Maverick box and got to
know that this bug:
https://bugs.launchpad.net/ubuntu/+source/wxwidgets2.8/+bug/632984 makes
it impossible to compile wxRuby. I then tried to compile wxWidgets
myself, and it seemed to work, but today I started serious developing -
I got plenty of segmentation faults.
I decided to follow the guidelines at the wxRuby wiki (
http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets )
*exactly*, but it didn't work out[1] either, I'm still getting segfaults
when using more complex controls than the StaticText widget. For example
running the minimal.rb sample from the wxRuby gem and clicking the
"File" menu results in this: http://pastie.org/1229483
So, what is the correct way to comile wxWidgets on Ubuntu in order to
make it work with wxRuby?

Vale,
Marvin

[1]Btw. the step "cd contrib/stc" is not possible, that has to be "cd
contrib/src/stc" or just "cd contrib" (which builds all contributions
and was what I did).

Hello.

I have a ruby 1.9 and create a file trap.xrc in DialogBlocks.

Later I create a trap.rb: xrcise -o trap.rb trap.xrc ... All good.

But late I create a file ed.rb:

-------

require 'wx'
require 'trap'

class Exsys < wxFrame
  def initialize
    super
  end
end

Wx::App.run do
  Exsys.new.show
end

-------

It doesn't work! Why?

Please open attached image 'xx.jpg', here wrote error.

I believe your using Ruby 1.9.2, and if so, it no longer references the
current directory, or rather the directory from where the script is launched
from, as a path in which to look for files to require in.  You can do one of
two things, you can either do:

require 'wx'
require './trap'

or you could do:

$:.unshift "."
requrie 'wx'
require 'trap'

Either of these methods will work to get trap.rb to load up under 1.9.2.
 This isn't so much a wxRuby Problem, as it is a design change by Ruby 1.9
core.

hth,

Mario

Thanks, Mario! Now I have else three problems.

1) I create an XRC file with a label, combobox and button

---------- XRC

<?xml version="1.0" encoding="UTF-8"?>
<resource version="2.3.0.1" xmlns="http://www.wxwidgets.org/wxxrc">
    <object class="wxFrame" name="ID_WXFRAME" subclass="TFB">
        <style>wxCAPTION|wxSYSTEM_MENU|wxCLOSE_BOX</style>
        <size>640,480</size>
        <title>FFF</title>
        <centered>1</centered>
        <object class="wxBoxSizer">
            <orient>wxVERTICAL</orient>
            <object class="sizeritem">
                <flag>wxALIGN_CENTER_HORIZONTAL|wxTOP</flag>
                <border>220</border>
                <object class="wxStaticText" name="wxID_STATIC">
                    <label>Check your location</label>
                </object>
            </object>
            <object class="sizeritem">
                <flag>wxALIGN_CENTER_HORIZONTAL|wxALL</flag>
                <border>5</border>
                <object class="wxComboBox" name="where_are_you">
                    <size>100,-1</size>
                    <style>wxCB_DROPDOWN</style>
                    <content>
                        <item>USA</item>
                        <item>Canada</item>
                    </content>
                </object>
            </object>
            <object class="sizeritem">
                <flag>wxALIGN_CENTER_HORIZONTAL|wxALL</flag>
                <border>5</border>
                <object class="wxButton" name="next_btn"> # HERE
                    <label>Next</label>
                </object>
            </object>
        </object>
    </object>
</resource>

----------- RB

# -*- coding: utf-8 -*-
require 'wx'
require './trap'

class Exsys < TFB
  def initialize
    super
    evt_button (next_btn) {next_go} # HERE
  end
end


def next_go
  # Many Testing Code
end


Wx::App.run do
  Exsys.new.show()
end

--------

I need to start an def next_go, if I click button next_btn (see HERE
places in the code). It doesn't work, see the attached image.

2) How I can read a value from ComboBox?

3) How I can disable and enable Sizer?

The next_btn should actually be accessable through @next_btn, since you are
inheriting the TFB class in your Exsys class.

Try doing: evt_button(@next_btn) { next_go }

See http://wxruby.rubyforge.org/doc/combobox.html  Specifically #get_value
and #get_current_selection.  Since ComboBox has a TextEntry and a Choice
setup with it, you need to compare between the TextEntry and Choice to
ensure you are getting the correct value out of it.


> 3) How I can disable and enable Sizer?

First you need to get the sizer, by using Window#get_containing_sizer, then
you can use Window#hide, or Window#show to hide/show a Sizer, and
Window#disable or Window#enable to disable/enable a set of controls.

There's no physical way to disable a Sizer to prevent the sizer from
resizing in the window.  You can only either hide / show it, or
enable/disable the controls within it.

This stupid thing prevents me from continuing developing. Do I really
have to go back to Ubuntu Lucid to get wxWidgets/wxRuby to work?!

Ok I tried unsuccessfully to get wxRuby2.0.1 to work with either ruby1.8 
or ruby1.9 and Ubuntu 10.04 by compiling according to the instructions 
previously mentioned.

Does someone have a gem that works?  Do I have to remove all traces of 
wxruby first?  What do I need to do to get wxruby working again?

Thanks

-Philip

On Ubuntu 10.04 it should work with the wxWidgets packages without
problems. Do a
$ sudo apt-get install libwxgtk2.8-dev freeglut3-dev
then set the symlinks I mentioned in my previous post. Afterwards
install SWIG 1.3.38 (newer versions won't work) and ensure the SWIG and
Ruby executables are in your PATH.
Now unpack wxRuby and
$ cd wxruby-2.0.1
$ rake
$ strip -x lib/wxruby2.so
$ rake gem
and you should be done. Works for both 1.8 and for 1.9. But not on
Ubuntu Maverick, because a bug was introduced that makes it impossible
to compile wxRuby (see another thread of mine a few days ago).

Note however that I do not use the Ruby provided by Ubuntu. I think they
compile it without the --enable-shared flag wich is required by wxRuby
and apart from that the Ruby provided by the Ubuntu packagers is a bit
out of date. Therefore I compiled Ruby myself into
/opt/rubies/ruby-1.9.2-p0. If you want to that as well, I recommend you to
$ sudo apt-get install libssl-dev zlib1g-dev libreadline5-dev libyaml-dev
before, otherwise your're missing some important C extensions (mainly
ZLib: Rubygems depends on it).

Subject: [wxruby-users] Already Initialized Constant THE_APP
Message-ID: <70409c46fec828bf3fdb58d0f4a8808d@ruby-forum.com>

Hello everyone. First time here.

I'm posting a debug question because I've searched google all over and I
can't find any other instances of this occurring. And even though it may
be a common error due to a stupid mistake by me, who is just learning
ruby and wx, for some odd reason the internet seems devoid of a
solution. I've even searched this forum and the error message is not
here either.

What happens is, the script brings up the login/create window just fine
the first time, but if the user enters too short a password and the
script tries to bring the same window up a second time for another
chance at input, the program crashes with exception "Already Initialized
Constant THE_APP". I've tried rewriting it multiple ways, even the basic
App.run do   method. Still no luck.

It seems like I'm not doing something that is needed to completely
destroy the instance of App, as the second time I call it no matter what
it always crashes with the exception.

What's funny is, I had this login/create window already done using the
TK library and since I had an old version of the library, it had a bug
in PMW which basically caused the same kind of behavior as this bug is
causing. I could only bring up one instance of anything, if another was
ever created, even after all other instances had been destroyed, the
program would crash and tell me that a constant was already initialized.
Without a way to fix it, I moved on to shoes, which I quickly dismissed
because it was WAY too hard to try and get shoes to work from within my
ruby script instead of as a script-launcher. Then I spent a good 5 hours
researching a way to make "require 'wx'" work, turns out ubuntu 10.04
needs some special installation procedures. Finally got that working,
only to find out that, yep, I can only create one instance of a window
per program run......... again....   XD

I realize that I can just handle the string check in the button code to
avoid this one occurrence. However, that won't fix the problem if I need
to be able to reopen a window later in the program. The real problem is
that later on I will be developing a lot of GUI windows for this client
that will need to be opened, then closed, then reopened, then closed,
then reopened, over and over and over again, in order for players to
build. If I can't do it with the first window, it's not worth building
all the subsequent windows or even continuing on the project until I can
find a GUI that allows me to create a second instance of a particular
window sometime after the first instance had been destroyed.

Here's the contents of obtainlogin.rb. This file is required in the main
ruby script.

I'm using Ubuntu 10.04 Lucid and Ruby 1.8

Hello Ron,

First off, welcome to wxRuby.  Your lucky I'm up this early, as I should
have been in bed an hour ago, but you know how it goes. lol

The answer to your solution, is to intercept a evt_close on your window
class, to prevent the window from being destroyed.  What is happening, is
when you run your script, the App instance is initialized with Wx::App.run
method.  And the thing is, there can only ever be one instance of Wx::App at
any run time of your script.  So if you exit out of the Main Loop for
Wx::App, then it's going to fail, when you try to re-initialize / re-create
your App / Window.  Mainly cause your trying to re-create your Window, after
wxWidgets has already released the App Instance.

The solution to your problem, is two fold.  First off, move your logical
handling code into your Window class.  This will ensure that your code is
executed, and allow wxWidgets to continue operating for you.  You should
never exit the Wx::App main loop, unless your actually exiting the program
itself.

Second, if you want your window to dis-appear, but the app to remain
running, you need to do two things.  One, ensure that Wx::App, doesn't exit
when the Main Window Instance (The first / Only instance of a Wx::Frame) is
destroyed.  This can be done with Wx::App#set_exit_on_frame_destroy() method
(Referenced here<http://wxruby.rubyforge.org/doc/app.html#App_setexitonframedelete>).
 This will ensure that if there are no other Window instances available,
that wxWidgets will not close out the app, and de-reference the main
instance of the App.

The second part, is that there are two ways to handle getting rid of a
Window.  The first, obviously being the close method, which will close the
window, and Destroy the reference to the Window.  Which will require you to
re-create a new instance of the Window.  The second method, is to simply
hide the window.  This is different from minimize, you just use the hide
method on the Frame itself, and it will make the window dis-appear, looking
as though it had been closed, but the Window instance will not be destroyed,
and you will have it available, to re-display to the end user, should you
need to use the window again.

I hope that this helps you understand what is going on.

L8ers,

Mario

Hey Mario, thanks for your quick reply. Incredibly informative too, now 
I have a lot of options to deal with the login screen.

I am a little confused though. I still don't see a way to have more than 
one window in the entire ruby script.

"And the thing is, there can only ever be one instance of Wx::App at any 
run time of your script."
"You should never exit the Wx::App main loop, unless your actually 
exiting the program itself."
>From what you say here it almost sounds as if every ruby script can have 
only one window and no other. What if I needed to use app to show a 
login screen first, then after that a main game window, etc? I could 
still have the main script running while the main_loop is running if I 
gave the window its own thread, but that would still be the only 
allowable instance of the app in the entire program? If there can only 
ever be one occurence of app in the code, and to create two different 
windows from two different classes one would need two occurences of app 
in the code...  XD      doesn't that mean each rubyscript can only ever 
have one window?

I see how the hide method can be useful for the login screen, and I can 
certainly place the string verification code into the frame class. 
Definitely a solution for the exception on the login screen. But I still 
need to have the same ruby script create a main game window after the 
login screen is finished/hidden.

Is there perhaps a way to create a second window and show that one 
within the execution of the same main_loop? I could automate control of 
the main_loop in its own thread through global variables.

Is there any way at all to have two different windows in the same ruby 
program?

I'm thinking that if instead of requiring obtainlogin.rb I could perhaps 
execute it as a separate process from the main script, and then I could 
launch another process later for the main game window, but then global 
variables wouldn't be shared with the main script. Would have to mess 
with pipes to do that?

Also, if it's impossible to have more than one window with wxRuby, is 
there another rubygem GUI library that anyone knows about which would 
allow two different windows to be opened in the same ruby script? 
Somehow it seems like I must be missing something because I wouldn't 
expect such a large robust library to be limited to 
one-window-per-program.

Okay, I understand where your confusion is below, I'll just skip down below
all this, and explain it in better detail.

Alright, with all that out of the way, the first thing you will need to
realize, is that Wx::App, isn't a Window Class, and is not sub-classed of a
Wx::Window or Wx::Frame.  If you goto the API reference documentation,
http://wxruby.rubyforge.org/doc/app.html, and look for the Sub-Section of
Derived From, you'll see that Wx::App descends from Wx::EvtHandler and
Object.

I don't know what kind of programming background you have, but to look at
wxRuby in the fashion of a MVC (Model - View - Controller) setup, Wx::App
would be the Controller setup. It's your Main Entry Point into running your
program, and deciding where to go.  Wx::App.run, or Wx::App#on_init is your
Main Entry point, into your entire program, all your windows will either be
created from here, or be setup to be ready to be created from the rest of
your program.  All your initialization of library functions, and data stores
you need, would be done from this method.

The View Part, actually falls under the class of Wx::Frame.  There's a
common mis-conception when first dealing with wxWidgets in general, the
difference between Window, and Frame.  Mainly cause of Microsoft Windows,
and how their API is setup, Window means Window.  An actual window displayed
to the user, that has a minimize, maximize, and close button on it.

Where as with wxWidgets, what is considered a window, is actually considered
a Frame, with a minimize, a maximize, and a close button on it.  A Window in
wxWidgets is actually considered any control that can be displayed on the
screen.  You'll find if you go through the API Documentation, and look at
the sub-section Derived From, a good 90 percent of them, have the Window
class in it.  The exception to the rule, is of course Sizers, Menus,
AuiManager, etc, etc, where these are basically internal data structures,
that wxWidgets utilizes, to create the necessary UI Elements on Linux,
Windows, and Mac OS X.

Each Platform, and basically each GUI Toolkit has different methods in which
to handle the above cases of items, or may not have them at all (As with
Sizers aren't native to Windows, but is available on Linux with GTK and on
OS X with NSView, and with Menus, Windows and Linux with GTK have Menu
Items, where as OS X has Data Entries to Represent Menu Items.)  So, let's
say with your Example, your wanting to do a Development of a Game, where you
have a Login, and a Main Display Window, where the Login is a User Prompt to
ask for Login information to get into the game, and the Main Display Window,
is where all actual game play occurs.  I'll give you a very basic design to
show you how it works, and explain it further with comments.

I'm writing the code as I go, so it may not be 100 percent correct, but you
should be able to run the code, without any problems.

-- CODE BEGINS HERE --
#!/usr/bin/env ruby

# Here we are loading wxRuby by any possible means, either by a system
# install, or by a Ruby Gems install.  If we can't find a system install,
then we
# will try to load through RubyGems, if available, and if that fails, we'll
just

# This is the window that will be the Main Display Window

  def initialize
    # The parent of this window is desktop, so nil is used
    # We don't need a specific ID for this window, so -1 is used
    # Our Title for our new Window is "Game Window"
    super(nil,-1,"Game Window")
    # Here we create all of our stuff needed to play the game,
    # such as UI Elements, and stuff that needs to be displayed in
    # The game Window.  No other window controls are created here.
    @te =
Wx::TextCtrl.new(self,-1,:pos=>[0,0],:size=>[200,20],:style=>Wx::TE_RICH2|Wx::TE_AUTO_URL|Wx::TE_PROCESS_ENTER)

  def input_handle_enter
    Wx::MessageDialog.new(self,"You entered: #{@te.get_value}","User Input",
        Wx::OK)
  end
end

# Now we setup our Login Window, which will be displayed first, then will
pass off to
# the Main Display Window to continue running.
class LoginWindow < Wx::Frame
  def initialize
    super(nil,-1,"Login")
    table = Wx::GridSizer.new(3,2,0,0)
    table.add(Wx::StaticText.new(self,-1,"Username:"),0,Wx::ALIGN_LEFT)
    table.add(@user = Wx::TextCtrl.new(self,-1,""),1,Wx::EXPAND|Wx::ALL)
    table.add(Wx::StaticText.new(self,-1,"Password:"),0,Wx::ALIGN_LEFT)
    table.add(@pass =
Wx::TextCtrl.new(self,-1,"",:style=>Wx::TE_PASSWORD),1,WX::EXPAND|Wx::ALL)
    table.add_spacer
    table.add(@login = Wx::Button.new(self,-1,"Login
>"),1,Wx::EXPAND|Wx::ALL)
    self.set_sizer(table)

    evt_button @login, :on_login_push
  end

  def on_login_push
    uname = @user.get_value
    upass = @pass.get_value
    unless uname.empty? AND upass.empty?
      # Attempt to login here, and process success or failure.
      if success
        gw = GameWindow.new
        gw.show
        self.hide
      end
  end
end

class MyGameApp < Wx::App
  def on_init
    lw = LoginWindow.new
    lw.show
  end
end

MyGameApp.new.main_loop
-- CODE ENDS HERE --

As you can see, I create the Login Window, which handles the login process,
and if it's successful, then will create the game window, and hide itself.
 The App is still running, and never exits, and your windows will continue
to display, and run, and you won't get any Pesky THE_APP already initialized
segfaults.  Now, keep in mind, if you want to call methods on your App
class, you can simply use the method Wx::get_app(), or you can use
Wx::THE_APP to get the instance of your main App, and execute the method on
it.  Though, it's strongly suggested that you don't put game loops and such
that require access to your Game Window, in your App, as your crossing
between objects, and the self reference changes between Objects, when you
get to that point.

EG: Calling a Method on your App class, means self refers to the instance of
the App class itself, where as calling a method on your Window class, means
self refers to the instance of the Window class.  And by that, instance
variables will be different between the two, or non-existent between the
two.

I hope this makes things clearer.

Sorry Michael,

I tend to not get much time to respond to emails, as I'm trying to run
through everything.  Could you send me attached a copy of your XRC, and Ruby
Source files, so I can see where the problem may be in the code?

Thanks,

Mario

I'm sure I've done something basic wrong, but I don't see it. I'm running MAC OSX 10.6.4

I installed using ruby gems:

 include Wx 
 

 class MinimalApp < App
    def on_init
         Frame.new(nil, -1, "The Bare Minimum").show()
    end
 end
 

 MinimalApp.new.main_loop

Yes, that is much clearer. Thanks for taking the time to write the code 
and show me.

I realize I probably seem like a Ruby noob. I've been learning Ruby for 
almost two weeks and so far I love it. I've coded games in VB6 and 
PHP/MySQL and Flash Actionscript, and I've coded other kinds of programs 
in C++. Ruby is definitely different but I can see a lot of good 
qualities from different languages packed together into Ruby.

I found Rubygame library and it looks great for the graphical combat 
screen, but has absolutely no utilities like buttons/textboxes/etc, so 
it's great that Wx can still be used.

I also see what you mean by having to put all the code of the client 
into the Wx classes. I'd prefer if possible to leave things like the 
connection protocol, socket communication, macro key functions, sound 
effect calls, etc, outside of the frame classes and the main_loop.

If I wanted to keep handling connection events from the main script 
while the main_loop was executing, I could use a separate thread for the 
main_loop, but would there be a way to hide/show a frame from a thread 
outside the main_loop? Like 'def methodX; self.hide; end' in one of the 
frame classes, and '$loginFrame.methodX' from outside the main_loop 
thread? Or $loginFrame.hide?

I know I can call methods defined by the main-thread from spawned-thread 
blocks so it ought to work the same way in reverse if I use global 
variables for all the frame instances?

Your post is missing the actual error. The string literal warning occurs
many times during compilation and shouldn't lead to an interruption.
Did you compile wxWidgets yourself? I'm wondering, because your include
path shows /usr/local/lib/wx, which should be /usr/lib/wx I think.
What is the output of

$ ruby -rrbconfig -ve 'puts RbConfig::CONFIG["configure_args"]'
$ dpkg -L libwxgtk2.8-dev
$ which wx-config

?

When I search with Finder, I cannot find ANY files (other than my test program) with wxruby or wx_ruby in the file name. Does this mean the gem didn't install the ruby bindings? The install appeared to work.

Thanx - Charlie

OK guys, I'm one step nearer to the goal of a usable wxRuby on Ubuntu
Maverick... I decided to give the distro packages another try and
thought the the missing libwx_gtk2u_media-2.8.so.0 shared object file
should only affect the MediaCtrl. I tried to exclude MediaCtrl from
compilation via the WXRUBY_EXCLUDE variable, but I got to know that the
INSTALL file contains a fatal typo: After looking through wxRuby's
Rakefiles I found the variable is actually named WXRUBY_EXCLUDED (note
the letter *D* at the end). So I tried
=====================
$ export WXRUBY_EXCLUDED=MediaCtrl
$ rake
and it compiled successfully! So I continued:
$ strip -x lib/wxruby2.so
$ rake gem
=====================
But nope:
=====================
(...)
Cannot build a package without a version being specified
Create a version by running rake with WXRUBY_VERSION=x.x.x
(...)
=====================
OK, not that hard.
=====================
$ rake gem WXRUBY_VERSION=2.0.1
rake aborted!
can't modify frozen string
(...)
=====================
Uh! What's that? Following the backtrace, I found it was line 22 in
rakepackage.rb which caused the error. I changed it from
=====================
spec.version = WXRUBY_VERSION
=====================
to
=====================
spec.version = WXRUBY_VERSION.dup
=====================
and finally, I got my gem file!
=====================
$ rake gem WXRUBY_VERSION=2.0.1
(in /home/quintus/Downloads/wxruby-2.0.1)
Enabling DYNAMIC build
Enabling RELEASE build
Enabling UNICODE build
The following wxWidgets features are not available and will be skipped:
  MediaCtrl
  MediaCtrl
  MediaEvent
  PrinterDC
  Successfully built RubyGem
  Name: wxruby-ruby19
  Version: 2.0.1
  File: wxruby-ruby19-2.0.1-x86_64-linux.gem
=====================
It's interesting that MediaCtrl shows up twice in the list of skipped
features. Without the WXRUBY_EXCLUDED variable set, it appeared once,
but nevertheless wxRuby failed to compile saying
libwx_gtk2u_media-2.8.so couldn't be found. I had to explicitely exclude
the MediaCtrl class to get rid of that dependency.
Now I continued with installation of the gem (which went just fine; I
even removed my previous wxruby-ruby19 gem to avoid conflicts) and tried
to run the minimal sample:

I found my problem; I had to use the 32 bit instead of the 64 bit 
architecture, and the sample program works.

Out of curiosity, why do I need the "require rubygems" line before the 
"require wx" line?

Thanx - Charlie

It seems you have two wxWidgets installations, one in /usr (that's that
one from the Ubuntu repos) and one in /usr/local (probably
self-compiled?). /usr/local/bin comes first in PATH, therefore the
wxWidgets installation there is used by wxRuby. Try this:

$ wx-config --prefix
$ /usr/local/bin/wx-config --prefix #Same as above
$ /usr/bin/wxconfig --prefix

and two different wxWidgets prefixes will eventually be shown. Building
on "top of the distro packages" should work fine, so I suggest you to
uninstall the wxWidgets in /usr/local/ either by running

$ sudo make uninstall

in the source directory of the compiled wxWidgets, or, if you don't have
that source directory anymore, a

$ cd /usr/local
$ find -regex '.*libwx.*' -or -regex '.*/wx-.*' -or -name wxrc

*should* list all wxWidgets files under /usr/local. Deleting those
*should* result in a complete deletion of the wxWidgets installation in
/usr/local. However, do review the list of found files; deleting
something non-wxish unintentionally can cause problems (as you might
imagine). For instance, on my system this shows some Python files:

$ find -regex '.*libwx.*' -or -regex '.*/wx-.*' -or -name wxrc | grep py
./include/wx-2.8/wx/wxPython/pytree.h
./include/wx-2.8/wx/wxPython/pyistream.h

Because you've used the "gem" command to install wxruby, it's as simple 
as that :-)

One thing to note though:

>> Successfully installed wxruby-1.9.3-universal-darwin
>> 1 gem installed

This is an old version of wxRuby - it's better if you grab the latest 
from here:
http://rubyforge.org/frs/?group_id=35

( For OSX 10.6: 
http://rubyforge.org/frs/download.php/63386/wxruby-2.0.1-universal-darwin-9.gem)

For some reason this package isn't available via gem command. Once you 
download the file just run:

gem install wxruby-2.0.1-universal-darwin-9.gem

(make sure you uninstall the 1.9.3 wxruby first).

Hope that helps.

Hello All,

Due to some issues with the setup of 10.10, I've been working on getting a
new version of the wxRuby gems setup, and ready for you all.  Currently,
since it was the one requested by Phillip Stephens, I've posted a Ruby 1.9
Gem which can be downloaded from
http://www.trilake.net/wxRuby/wxruby-ruby19-2.0.1-x86-linux.gem

This version of the gem, has been compiled to work without wxMediaCtrl
compiled in with the main wxWidgets Library.  I will be setting up a new
distro in my Apt repository to upload new versions of the wxRuby library for
i386 and x86_64, specifically for Maverick Meerkat.  I will be setting up my
64bit install of Ubuntu to host a VM for Lucid Lynx, to get installs for
both 32bit and 64bit versions for 10.04.  I apologize for the lateness in
this post, but I was just able to get everything compiled, and uploaded.

Please bear with me, as I get the repositories setup, and going with proper
authentication of the source packages, and such.

hth,

Mario

P.S. Installation instructions in a Copy & Paste Method for the Gem:

wget http://www.trilake.net/wxRuby/wxruby-ruby19-2.0.1-x86-linux.gem
sudo gem install wxruby-ruby19-2.0.1-x86-linux.gem

Not a problem, and I'm glad that you can finally understand where this is.

Ruby is Unique in the fact that it's pure Object Oriented, and therefore,
fits many encapsulations of elements within a program.

Threads are a tricky business, especially when you get into Multiple
Threads, and that you also need to realize something else.  Depending upon
what version of the Ruby Interpreter your using, you have to deal with
another layer of trouble.  In Ruby 1.8, it is designed at the core, to use
Green Threads.  Which basically means, that a Thread is created internally
in the Interpreter that is basically an Emulated Thread, but not a true
native thread.  This basically means that Ruby is handling all the
scheduling and such for each of the threads, instead of the OS itself.  Ruby
1.9 on the other hand, actually implements Native threads, where the OS is
handling the Threads itself, and not Ruby.

What this means to you, is that if you were to use Ruby 1.8 Threads, and you
have something like wxWidget's main_loop running, 99.9999 percent of the
time will be spent on main_loop, giving ruby extremely little chance to run
any other threads.  If at all.  Where as Ruby 1.9, it handles Threads
natively, which allows main_loop to run in it's own native thread, and
allows you to create other threads, in which to actually
run simultaneously as the Main Thread.

Which brings me to Thread Safety.  The main thing you want to be careful
about with dealing with Threads, is using them safely.  Thread Safety
basically entails using a Mutex, or Semaphore to get a global lock within
your program, and allow a certain thread to have exclusive access to the
variable data, including updating it with new information, while preventing
other threads from having access for the time that your updating the data.
If all your doing is Reading Variables, and not assigning to them from
another thread, then you should be fine.  But if your assigning data from
other threads, then you need to create a Mutex, lock it for the period that
your updating the data, then unlock it when your finished.  If you don't,
then you could get those nice little fatal errors, about access violation of
memory addresses.  I'm sure with your C++ background, you probably have a
good idea what I mean by this.

Lastly, another thing you will need to be careful of, is the whole usage of
two different libraries, that utilize a tight end Main Loop.  RubyGame
utilizies a tight end Main Loop to allow processing of drawing, events, and
so on, while wxWidgets also has it's own tight end Main Loop, to handle the
same things.  Attempting to use these two in conjunction, requires a bit of
advanced programming to get to work properly.  Not to say that it can't be
done, it can, but it will be hard to do, as you will need to write a sort of
merged main loop, that will handle wxRuby events, and handle RubyGame events
at the same exact time, to keep both libraries running smoothly, as if they
were separate.

Thankfully, wxRuby allows you to write your own main_loop function, if you
were to sub-class Wx::App.  and using Wx::App#pending to see if there are
any wxWidgets events pending, and if there are, using Wx::App#dispatch to
dispatch events to be executed.  Using this in concert with RubyGame, or any
other library's own way of processing their own events, may help you utilize
what you want to keep things running smoothly.


I do hope that this helps you out, and progresses you further in developing
your application / game.

I'm really interested in how you managed to do a successful compile on
Ubuntu Maverick. I've been trying to do that for more than a week now
and still no success (see my previous posts on this lists, e.g. here:
http://www.ruby-forum.com/topic/260671 ). Even if compilation was done
without problems, I was bombed with segfaults when trying to use wxRuby,
even with the minimal sample a click on the "File" menu made Ruby crash.
Could you post some instructions on how to get that working (maybe in a
new thread, as this is not what the OP is trying to do)?

Vale,

Hello All,

In regards to Ron's post, I have reviewed the gem created by the build
process, and attempted to use it, and it is as you said, with Ruby 1.9.2 p0,
when attempting to run most of the examples, it will cause a segfault, with
a ruby backtrace, and debugging info, suggesting something has gone wrong.
 I've also attempted to build against Ruby 1.8.7 p302, and it seems that it
has issues with rb_intern2 not being found for some reason.  I just joined
#wxruby on irc.freenode.net, if you are still available, we can research
what is going on, and figure out a solution to this problem.

I've searched these forums and found some tips, tried some of them but 
they haven't helped yet. I don't need to boost GC speed because I am 
getting the fault in the same place all the time, it's just that 10% of 
the time it does not occur and the creation screen shows and behaves 
normally. I tried GC.disable in my script but that didn't solve the 
problem, so I don't think it's caused by garbage collection.

This answers a big question of mine. The client stops communicating with 
the server when the GUI is shown, until I start moving the mouse. The 
client only continues to process the socket thread if I continue to move 
the mouse. So if I run it on ruby1.9.1 that'll take care of that 
problem?

Turns out I can't uninstall ruby1.8 without removing ruby completely. 
Ruby doesn't run if I have only 1.9.1 installed, oddly enough. So should 
I just leave ruby1.8 installed and install ruby1.9.1? Will that mean any 
script I run will automatically use ruby1.9.1? RVM seems to be way too 
complicated, not sure if I want to use RVM.   XD

I will definitely need to be modifying the properties of the class 
instances that are initiated within the main_loop, from outside the 
main_loop in the socket thread. So it sounds like I'll have to be using 
locks. Thanks for telling me about that, probably would have taken me a 
while to find that.

Also - this is probably what is causing the segmentation faults? The 
fact that I don't have synchronized blocks / mutex locks?

What if I don't need to execute any code in the wx main_loop while the 
Rubygame main_loop is running? I can handle the combat mode using only 
Rubygame.

Does that mean that, instead of rewriting the main_loop, I could just 
execute the Rubygame main_loop from inside of the wx main_loop? I could 
tell the wx main_loop to sleep while the Rubygame main_loop is 
executing, just to make sure it waits for combat to end.

Yeah, you've been incredibly helpful. I don't think I would have got 
WxWidgets to show multiple windows without your explanation on the 
main_loop etc. Thanks! :)

...

# this method is in class MainScreenFrame < Wx::Frame
def showPlayerCreationScreen
# this method ends up getting called from the socket thread.
$mutex.synchronize {
$theCreationScreen = PlayerCreationFrame.new()
$theCreationScreen.show # segmentation fault occurs on this line

I've placed puts at the end of the def initialize method in the 
PlayerCreationFrame class, and the puts always gets shown before the 
segmentation fault occurs, so it's not occurring with initialization of 
PlayerCreationFrame (unless it occurs as the initialization method 
ends?).

GC.disable has no effect.

After doing a complete wipe clean of the code, and re-swigging and compiling
of the code, it looks as though Ruby 1.8.7 p302 has the same issue as Ruby
1.9.2 p0.  In the fact that aside from a few configuration errors on our
part, with the removal of wxMediaCtrl from the Debian/Ubuntu repository
version, that after getting the errors fixed, there's an issue with
libpixman, in the function pixman_image_composite32, running through the GDB
backtrace.

I am therefore going to attempt to custom build wxWidgets myself, in static
form, and build wxRuby's so file in static mode, to see if the errors
progress, or fix.  It may be solvable by using wxWidget's internal graphics
libraries over the system's libraries, but I won't know for certain till I
run the compile.  I'm getting things setup now, to see what happens, and
will post on my progress once I get a version built.

L8ers,

Mario

Awesome, will drop on by. That's an IRC chatroom on freenode, right?

Alright, after running through various self-compilation tests, and switching
between 1.8.7 p302 and 1.9.2 p0, I've ended up with the same results,
pixmap_image_composite32() for some reason is causing a segfault in wxRuby,
no matter the circumstances.  I've had it crop up in a good portion of the
examples, and been trying to backtrace the issues to their problems.  Sadly,
it seems that it doesn't matter which class is being used, and it doesn't
matter which example is being tried out, it will still cause the same
problems.  Sometimes it'll wait till the user does an action, such as menu
click, or it will crash immediately after the start of the run.

And it always crashes on pixmap_image_composite32().  From what I've found
of the libpixman library, it's a drawing function that will basically blit
an image with a composite form from src, to destination.  So it is some kind
of drawing function, but somehow it's crashing.  And I've tested with
various C++ Examples provided with wxWidgets, and they all seem to operate
perfectly fine.  I'm currently at a lost as to what is causing this.

You may laugh, but I already tried that. Even with a self-compiled
wxWidgets in static mode (exact build options I used can be found in the
wxRuby wiki at
http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets ) I got the
segfault. I compiled wxWidgets to the /opt/wxWidgets dir and tried to
run files like this:

$ export LD_LIBRARY_PATH=/opt/wxWidgets/lib
$ export PATH=/opt/wxWidgets/bin:$PATH
$ ruby -dw <file>

However, I might have done something wrong as it was the first time I
compiled wxWidgets.

Sadly enough, I'm not a C++ developer and don't have any knowledge of
SWIG. I've done some C programming, but I think I can't be of much help.
If it's any help I've joined the #wxruby IRC channel for now, but I
don't have much time.

Sorry for the late answer, but normally I'm not at home until 17pm.
Except on weekends, of course. Just for information: My time zone is UTC
+ 2 as I'm living in Germany, next week it will be UTC + 1 when daylight
saving time ends.

Vale,
Marvin

Subject: [wxruby-users] wxruby thread - gui updates
Message-ID: <AANLkTi=bYMxpDJgVsv+9sMrQG9oMFkCP-m-csxc1DJEy@mail.gmail.com>

Hi all,

i've a question about ruby threads and gui update events:

My app consist of several folders that needs to be updated depends on what
the user do.

Actually all the gui updates occurs in response to the user actions into the
main wxruby process.

It's just fine if the gui update takes short time but, sometimes, the gui
update is a long running task and the user get stuck waiting for the process
to complete.

It would be nice to have gui update running on a separate thread.

The first thing i thought was:

ok i use the wxThread to update my long running gui task but unfortunately
it's not included in wxruby distribution.

On the other side, using ruby thread in combination with Thread.pass is good
for external process not involving gui updates

So, what is the right way to go to update gui interface on a separate thread
using wxruby?

Any suggestion would greately appreciated.

bio.

Subject: [wxruby-users] Uninitialized Constant Wx
Message-ID: <30fcdeee3f42fd71ec315859197866da@ruby-forum.com>

Hello again. Another problem...

I installed RVM, and then installed Ruby 1.9.1. After that I used RVM to
make 1.9.1 the default Ruby version, and then I created a new gemset,
and then I told RVM to use that new gemset for Ruby 1.9.1. Then I did
"rvm gem install wxruby-ruby19".

After this, I ran my client script once to test it and it worked just as
well as it was working for 1.8. I concluded it worked and went on with
more coding. A few hours later when I was going to test the new code, I
started getting "Uninitialized Constant Wx" exceptions. So it appears as
though the client succeeded in loading Wx one time, and that the client
failed to load Wx every time afterward.

I tried setting the default version of Ruby to 1.9.1 again, guessing
that maybe it got reset to 1.8, but that didn't help.

Then I remembered that I ran the WxRuby19 Sample "wxClient.rb" in a
terminal after the first test of my client but before the next test of
my client. Could it be that running the sample script somehow dislodged
my client script from finding the Wx library?

I just checked by placing a puts statement immediately after the
'require 'wx'' and 'include Wx' statements and then commented out
'include Wx'. The puts wasn't shown in terminal. Looks like it is the
'require 'wx'' statement that is throwing the exception.

I'm also still getting that segfault crash with the boxsizers but I can
only deal with one bug at a time XD

Subject: [wxruby-users] Very slow blitting, trying to optimize.
Message-ID: <ad474d50b72e174971c9aedd53a95b83@ruby-forum.com>

Hello,

I'm coding a 2D map editor for a small game engine and I'm running into
blitting problems. The bigger my map is, the longer it takes to blit a
tile on it. sometimes, when I try to draw a tile to fast, it even fails
completely at blitting and I have to close and reopen the program for it
to work again.

I have attached the main drawing methods to this post.

How it works:

1) I have a custom cache class that creates and retrieves bitmaps on
demand to speed up things a bit. Used especially when using tiles,
layers or the whole tilemap bitmap. All get_X_bitmap methods you see are
used to retrieve bitmaps from cache.

2) The draw_layer and draw_tilemap methods have a rect argument. When
not nil, only the region specified by this rect is redrawn. Again, this
is to speed up the whole process.

I did some basic speed test using the Time class to see how log it takes
to blit a tile depending on the map size, using 32x32 tiles.

On a 20x20 map, the whole process takes around 0.032 to 0.041 seconds
On a 100x100 map, it can take up to 0.5 seconds

The most weird part is when I try to draw tiles to fast on a big map.
It starts to blit the first few tiles (with a log of lag) and then it
completly fails. Blitting now takes 0.0 seconds and nothing is drawn on
screen.

Any idea on how I can fix this?
And pease tell me if there is not enough imformation or source code, i
can provide more.:)

Thank you very much!
 - Sasha

I'm new myself but perhaps you can use EvtHandler#add_pending_event from 
a standard thread to invoke an event handler in the gui thread.  You 
could pass information with a custom event or set up a shared mutable 
object beforehand.

Subject: [wxruby-users] Panel with FlexGridSizer not collapsing correctly
Message-ID: <e96da3737ca36fa5df9627326b4b3925@ruby-forum.com>

I have a custom class extending Panel for drawing lines, which shows an
array being sorted.  The application does 6 at a time and so there is a
Panel ("gridPanel") with a 2x3 GridSizer managing them.  Each cell
contains another Panel ("arrayBorderPanel") with a 2x1 FlexGridSizer.
The top row holds a Panel ("drawPanel" -- a 1x1 GridSizer) with the
custom panel centered in it, and the bottom
holds several StaticTexts in a Panel ("infoPanel") with 1x3
FlexGridSizer.  The column and the top row of each arrayBorderPanel are
growable.  The infoPanels have growable columns but not rows.

The frame expands correctly, with the column of the arrayBorderPanel
expanding horizontally but only the top row growing vertically, and the
custom panels auto-center.  The problem is when the frame is decreased
below the original size.  In other guis I've used the drawPanels shrink
vertically but the infoPanels  stay fixed.

With WxRuby the infoPanels are the first to disappear.  I need these to
stay put.  Right now both drawPanels and infoPanels are added to sizers
with a proportion of 0 and the EXPAND flag.  I've tried giving one or
the other a proportion of 1 and/or removing the EXPAND flag from the
infoPanel sizer but this doesn't change anything.  I have tried
set_min_size on both the infoPanel and its FlexGridSizer but no change
there either.

Any help appreciated.

Oh, I got it.  Do everything, call Frame.fit, then set min_height on 
both sets of Frames.
