Subject: [wxruby-users] wxRuby 1.9.9 released
Message-ID: <490C92BB.6000106@pressure.to>

Hello

I'm happy to announce that wxRuby version 1.9.9 is now available for 
download and gem installation:

http://rubyforge.org/frs/?group_id=35&release_id=27842
gem install wxruby

On Linux, the default binary gem is now dynamically linked to wxWidgets. 
This means you'll need to install wxWidgets from your package manager. 
See below for more info.

== CHANGES ==

This recommended upgrade includes a substantial number of new GUI 
features, as well as fixing a number of bugs:

* Added the RichText framework, providing word-processor like editing of 
styled/formatted text and inline images
* Added a number of other useful GUI classes, such as VScrolledWindow, 
VListBox and HtmlListBox
* Added the StandardPaths and NavigationKeyEvent classes
* Fixed a number of bugs and warnings
* Binary builds for Windows and OS X are based on the latest stable 
wxWidgets, 2.8.9, so benefitting from upstream fixes

It had been planned that 1.9.8 was the last release before 2.0. 1.9.9 is 
a chance to give some new classes some testing time and get some fixes 
out there whilst finishing up the last few 2.0 blocker bugs (eg 
Clipboard probs on GTK, ScrolledWindow X errors).

== LINUX BINARY GEMS ==

Previous binary builds for Linux were, like those for Windows and OS X, 
statically linked - meaning the wxRuby library included all the relevant 
wxWidgets code. With this release I've switched to offering a Linux gem 
that is dynamically linked - meaning it makes use of the wxWidgets 
library on your system - which should be easily installable from your 
package manager - eg apt-get install wxwidgets

The reasoning here:
* Because Linux systems vary a lot in what's installed by default, using 
the static build generally still required messing around installing new 
packages
* Package managers make it trivially easy to install a recent version of 
wxWidgets on major distros
* The shared builds are substantially smaller and may perform better

I'm open to discussion on this based on experiences on different distros 
(I've only tested on Ubuntu).

== ACKNOWLEDGEMENTS ==

Thanks to all those who contributed bug reports and feature requests to 
this release, as well as those who keep the project ticking over in 
other ways such as keeping the wiki up to date and taking part on the 
mailing list.

cheers

Subject: [wxruby-users] paint_buffered
Message-ID: <5ddda770eb0c149c683c34d8f4413087@ruby-forum.com>

Hello,

In order to reduce flicker in my paint-intense app I've switched from
paint |dc| to paint_buffered |dc|. Unfortunately, there is no difference
after switching. Does anyone know why? Are there any other workarounds
for this?

I'm on winxp, ruby 1.8.4, wxruby 1.9.9 (i've tried wxruby 1.9.8 but the
result is the same)

This is something that I've spent *many* days ripping my hair out over.
Eventually, I found that I was calling 'paint' when I should have used
'refresh'.
Could you supply us with some code so we could take a look?

Avoiding flicker in GUI apps is unfortunately not as easy as using 
paint_buffered, although it helps in a lot of cases.

It would be good to see some code that we can actually run, and more 
information about the app - eg is the refreshing event-driven (the user 
doees something, the display changes) or time-driven? To what extent can 
future drawing be predicted? Is the drawing itself complex, or is there 
a lot of computationally intensive non-drawing code in paint? Does 
everything change at once?

Depending on this different things might help - eg preparing drawing in 
idle time, only updating voided parts of the canvas, etc

Sure! Find memu.rb attached. It's a little hack, a monome emulator. You 
will need rosc by hans fugal for it to work - hans.fugal.net/src/rosc/. 
See www.monome.org for details about the actual device.

The MemuWindow is refreshed when a user presses or releases one of the 
buttons on the virtual device (mouse cursor and 
evt_left_down/evt_left_up). The box around the button is thickened. 
Also, when certain osc parameters are received, the leds within the 
buttons are lit up!

There is really no complex drawing going on, just a bunch of rectangles 
:), but it's rather important that the stuff is updated in realtime. 
Perhaps Ruby aint the ideal language for this.

Thanks, looks interesting although I have only a hazy idea what it's 
about. Please don't take this the wrong way, but if you're sending in 
code for advice it's much preferred that the code is self-contained (as 
yours is) and doesn't have external dependencies that need to be 
installed (as yours does). I and others on this list are really happy to 
try things out and advise, but it's too much to expect people to 
download, compile and install third-party libs to do that.

I haven't tried it out, but from reviewing your script perhaps I can 
make a few suggestions:

First, and most important, it looks like you're repainting the whole 64 
buttons when, for any given event, only one has changed state. An 
alternate and more efficient approach might be to make each LED a 
separate widget, an instance of a class inheriting from Wx::Window. It 
knows its state, and draws its own rectangle. The TargetControl class in 
the events.rb sample would be an example to look at for this.

You could then layout the buttons using a 8x8 Wx::GridSizer, store them 
in a two dimensional array (faster lookup than your buttons.detect 
method), then when an event is received, change the state of the 
relevant button and call refresh (or update) on it alone. This means 
that a much smaller amount of drawing has to be done for each change. It 
would also make your handling of left-down and left-up simpler as you 
wouldn't have to test which LED might have been hit.

Second, you might see whether, if each LED has only an on and off state 
and these look the same, whether it is faster to cache an image for each 
state and do draw_bitmap for each button. It may or may not be faster 
than drawing each one with primitives like draw_rectangle.

Third, you could try playing around with, instead of having the server 
in a different ruby thread, polling it for messages in evt_idle or 
directly in a timer (Wx::Timer.every(20) { server.serve }). Also, is it 
possible to have update the UI based only on server messages - ie 
evt_left_down only notifies the server of change of state, and the 
server notifies back to update the GUI? This design is generally more 
scalable, in my experience, than having the state-changing event handler 
also update the UI.

> Perhaps Ruby aint the ideal language for this.
Ruby's certainly slow, and while wxRuby's a decently fast GUI toolkit, 
the SWIG wrapping has significant overhead to each method call. That 
said, I used Jay McGavren's Zyps library, which draws a lot of 
primitives from scratch on a timed basis, and was able to get pretty 
smooth animation (definitely more than 20fps I think). You might find 
those wxruby-users threads in Dec 2007 / Jan 2008 of interest.

Message-ID: <236e49df0811050210g1286db8bq9f5d834a39b0d7d3@mail.gmail.com>

Hi,
I'm using TextCtrl and initially set some text in it. And all the text is
selected by default.
How can I deselect it?
By the way, TextCtrl#set_selection() doesn't work... What am I doing wrong?

Thanks a lot,
Kirill.

Here's the sample:

====================== wxtest.rb ===========================
require 'wx'

class TestFrame < Wx::Frame

  def initialize
    super(nil, -1, "Test")
    text = Wx::TextCtrl.new(self, -1, "first_line\n",
          :style => Wx::TE_RICH|Wx::TE_RICH2|Wx::TE_MULTILINE)
    text.append_text "second line"
    text.set_selection(3, 4)
  end

end

class TestApp < Wx::App
  def on_init
    TestFrame.new.show
  end
end

TestApp.new.main_loop

Great work, Alex!
By the way, the Windows version now seems to be much more verbose on errors.
This is very helpful, thanks a lot.

That's useful to know, thanks for following this up.

I think the difference is that I compiled the new version of wxWidgets 
for wxRuby 1.9.9 with wxUSE_EXCEPTIONS set 0 instead of 1. I'm guessing 
what was happening was that C++ exceptions were leaking through to Ruby, 
which is a bad thing and caused the uninformative crashes you reported.

I'll make this part of the official build instructions from now on.

Thanks for reporting this and providing a clear test case. I've tried it 
out and it seems to be a bug, specific to Windows. I was a bit surprised 
as I'm fairly sure this used to work.

If you're able, please could you file this on the bug tracker and attach 
your example as a test case. This will be a MUSTFIX for 2.0.

By the way, if you're using RICH and RICH2 for formatting, you might see 
if RichTextCtrl works better for you. TextCtrl + RICH2 has some 
cross-platform quirks, although it will be better for accessibility I guess.

thanks

Done:
http://rubyforge.org/tracker/index.php?func=detail&aid=22686&group_id=35&atid=218

And it also didn't work in 1.9.8, I just didn't pay attention to it at that
time.

By the way, is it also a bug that the whole text is selected by default?

By the way, if you're using RICH and RICH2 for formatting, you might see if

I'm not sure that I need all the power provided by RichTextCtrl, it looks
that for my task simple TextCtrl is just fine. But I'll try, thanks for
pointing to it.

Regards,
Kirill.

Subject: [wxruby-users] More rubish API
Message-ID: <236e49df0811050438x55e91c18v636e4250e82e304a@mail.gmail.com>

Hi,
Sometimes I find places in WxRuby API which seem to me not quite Ruby way
compatible. :)
I know (it's written somewhere on the wxruby site), that there is an acvity
to make WxRuby more Rubish.
I don't feel enough confident in Ruby or WxRuby to fully participate, but
I'd like to point to some places which could be improved.
Where is the best place to do it? This mailing list or bug tracker or
somewhere else? :)

For example, that's what I've noticed while examining RichTextAttr#apply:
"Applies the attributes in style to the original object, but not those
attributes from style that are the same as those in compareWith (if passed).

I'd mark combine as deprecated and use apply! instead, because that's what
exclamation mark is for. What do you think?

What I also would like to propose is to make set-methods "chainable".Currently
I have to do the following:
    style = Wx::RichTextAttr.new
    style.set_font_face_name("Verdana")
    style.set_font_size(10)
I would like to do:
    style = Wx::RichTextAttr.new
    style.set_font_face_name("Verdana").set_font_size(10)
etc.

This can be easily done by returning self object after modifying it.

I also would like to point that set_text_colour and set_background_colour
are named in a british manner (OUR), which is fine for
language, but is not traditional for IT, which uses color (OR). It looks
reasonable to change or at least alias this.

Thanks,
Kirill

Yes, I think so. It doesn't do this on other platforms.

Yes, me too. It's pretty much a straight port of the C++ wxWidgets API, 
with a few additions to make it more comfortable in ruby (eg 
accessor-like method names, using symbols to name event handlers, 
keyword constructors for Windows). And the wxWidgets API itself is not 
especially consistent across classes in the way that similar methods work.

This activity - which was under the project 'wxSugar' has kind of been 
in abeyance. Basically my time has been focussed on extending and 
correcting the SWIG wrapping. This stuff is pretty hard for newcomers to 
do - things like dealing with cross-language memory handling and 
wrapping virtual classes. But much of the syntax enhancement work can be 
done - or at least prototyped - in ruby.

We've also tried to keep the API stable since around version 1.9.2, so 
this has limited scope for big changes. But I would see wxRuby 3.0 as 
the place to be more radical and ruby-ify the API. I think then we also 
have a better view of all the places where changes might be desirable, 
to increase consistency.

Any contributions and discussions on these topics are very welcome.

Probably the wxruby-development mailing list for detailed syntax 
discussions.

I'd agree - but at the same time, I'd say it's important to make this 
change across all places it's relevant at the same time. There are a few 
other methods I think that have this pattern.

I'm not generally a fan of method chaining - to me your second example 
is less clear than your first. It's 40 or 50 characters without any 
white space.

I'd use a keyword constructor here, or a more declarative set of statements:

attr = Wx::RichTextAttr.new( :font_face_name => 'Verdana', :font_size => 
10 )

or

attr = Wx::RichAttr.new
attr.font_face_name = 'Verdana'
attr.font_size = 10

The second should already work.

Sure, if you would like this change, you can implement it yourself right 
away. Add something like this to your personal wx_additions library:

class Wx::RichTextAttr
  instance_methods.grep(/^set/) do | method_name |
    old_method = instance_method(method_name)
    define_method(method_name) do | *args |
      old_method.bind(self).call(*args)
      self
    end
  end
end

Hehe. I'm British and this is my single favo_u_rite feature of wxWidgets 
and wxRuby. To replace them in the core lib with nasty US mis-spellings, 
you'll have to prise them from my cold dead fingers. :)

Again, ruby makes it easy to change if it bothers you:

Wx::Color = Wx::Colour
alias :get_background_color :get_background_colour

etc

Hi,

I'm trying to use RichTextCtrl available with wxRuby 1.9.9 instead of
TextCtrl and the Enter key does not work (as what I expect).
With TextCtrl (with Wx::TE_MULTILINE), the Enter key creates a new line of text.
With RichTextCtrl, the Enter key changes the focus to another widget.

I saw a workaround for wxPython with the style WANTS_CHARS but there
is no such constant in wxRuby.
Thanks in advance.

Chauk-Mean.

Thanks for reporting this. I tried it out on OS X with my little 
RichText sample, where the widget is created with the default style and 
has no special event handling. The Enter key works as I'd expect - i.e. 
inserts a new line.

Do you perhaps have an event handler defined that you need to call skip 
on the event so that it's passed for normal processing?

Are you sure? It definitely seems to be available as Wx::WANTS_CHARS, 
with the value 262144.

If not, please report as a bug.

Hello together,

I tried to install wxruby 1.9.9 () on a SLES10 Linux server.

- First I installed the wxWidgets rpm.
- then the wxruby gem

When trying to start an example I get the following error:
/usr/local/lib/ruby/gems/1.8/gems/wxruby-1.9.9-x86-linux/lib/wxruby2.so:
libwx_gtk2u_gl-2.8.so.0: cannot open       shared object file: No such

... then next are available


I also installed all the available gtk libraries on the server.



Thanks for any help!

Subject: [wxruby-users] wxRuby 1.9.9 released

Hello

I'm happy to announce that wxRuby version 1.9.9 is now available for
download and gem installation:

http://rubyforge.org/frs/?group_id=35&release_id=27842
gem install wxruby

On Linux, the default binary gem is now dynamically linked to wxWidgets.

This means you'll need to install wxWidgets from your package manager. 
See below for more info.

== CHANGES ==

This recommended upgrade includes a substantial number of new GUI
features, as well as fixing a number of bugs:

* Added the RichText framework, providing word-processor like editing of
styled/formatted text and inline images
* Added a number of other useful GUI classes, such as VScrolledWindow,
VListBox and HtmlListBox
* Added the StandardPaths and NavigationKeyEvent classes
* Fixed a number of bugs and warnings
* Binary builds for Windows and OS X are based on the latest stable
wxWidgets, 2.8.9, so benefitting from upstream fixes

It had been planned that 1.9.8 was the last release before 2.0. 1.9.9 is
a chance to give some new classes some testing time and get some fixes
out there whilst finishing up the last few 2.0 blocker bugs (eg
Clipboard probs on GTK, ScrolledWindow X errors).

== LINUX BINARY GEMS ==

Previous binary builds for Linux were, like those for Windows and OS X,
statically linked - meaning the wxRuby library included all the relevant
wxWidgets code. With this release I've switched to offering a Linux gem
that is dynamically linked - meaning it makes use of the wxWidgets
library on your system - which should be easily installable from your
package manager - eg apt-get install wxwidgets

The reasoning here:
* Because Linux systems vary a lot in what's installed by default, using
the static build generally still required messing around installing new
packages
* Package managers make it trivially easy to install a recent version of
wxWidgets on major distros
* The shared builds are substantially smaller and may perform better

I'm open to discussion on this based on experiences on different distros
(I've only tested on Ubuntu).

== ACKNOWLEDGEMENTS ==

Thanks to all those who contributed bug reports and feature requests to
this release, as well as those who keep the project ticking over in
other ways such as keeping the wiki up to date and taking part on the
mailing list.

cheers
alex

I don't have any event handler on the RichTextCtrl.

Oups ! I wrote the constant correctly in this message but in my code I
wrote Wx::ACCEPTS_CHARS !!
Now, with a style set to Wx::WANTS_CHARS, RichTextCtrl works as expected.
So the workaround is actually applicable.
This may be defined as the default style at the the wxRuby level if
this does not harm on OSX and Linux.

Also, do you have / intend to add a RichTextCtrl sample ?

Cheers.

Thanks for the report. I think the problem is that the Ubuntu wxWidgets 
that the gem was built against was compiled in 'multilib' form - ie with 
each group of features in a separate .so. It looks like the .rpm you 
have was built 'monolithic' - ie with everything stuffed into a single 
.so. Could you see what "wx-config --libs" returns please?

I'm not sure how we get around this if different distros build in 
different ways. How did you get on previously with the statically-linked 
gems?

cheers

I'm a bit surprised that it behaves like this by default on Windows. I 
would have thought that the standard desirable behaviour for this kind 
of text editing widget would be to always consume Enter strokes.

I'll check that it's not something introduced by the wrapping, and if 
not, will do as you suggest.

I don't have one in a good enough state to be added, just a mishmash of 
stuff I used to test the various features as I added them. It would be 
very good to have a sample - I don't think it has to be as complex as 
the wxWidgets one - but at the moment writing samples is for me less of 
a priority than finishing the core lib. Contributions welcome.

Hi Alex,

thanks for the rapid answer!

1.
 wx-config --libs
-L/usr/local/lib -pthread   -L/usr/X11R6/lib   -lwx_gtk2_richtext-2.8
-lwx_gtk2_aui-2.8 -lwx_gtk2_xrc-2.8 -lwx_gtk2_qa-2.8 -lwx_gtk2_html-2.8
-lwx_gtk2_adv-2.8 -lwx_gtk2_core-2.8 -lwx_base_xml-2.8 -lwx_base_net-2.8
-lwx_base-2.8 


2. this is my first try to run wxruby on linux. Until now I used it only
on Windows.

cheers,
Franz

Thanks for the report. I think the problem is that the Ubuntu wxWidgets
that the gem was built against was compiled in 'multilib' form - ie with
each group of features in a separate .so. It looks like the .rpm you
have was built 'monolithic' - ie with everything stuffed into a single
.so. Could you see what "wx-config --libs" returns please?

I'm not sure how we get around this if different distros build in
different ways. How did you get on previously with the statically-linked
gems?

cheers
alex

Thanks. I think the problem is that the rpm version you have is a 
non-unicode build of wxWidgets, whereas I've built it against a unicode 
version. See that the libs it's looking for have a u in the name, eg 
libwx_gtk2u_aui, whereas the ones on your system don't.

I would suggest having a look in your repository to see if a "unicode" 
build of wxWidgets 2.8 is available, and installing that. wxRuby hasn't 
ever supported ascii-only builds of wxWidgets, and probably won't. 
wxWidgets 3.0 will make this easier by having a single utf8 build only.

Hi all,

in HtmlEasyPrinting how can i use PAGENUM and PAGESCNT macros?

I've tried to use them into an html text: Wx::PAGENUM and Wx::PAGESCNT using
set_header and set_footer

but i get them undefined.

Any suggestion would be appreciated.

They're not constants but placeholders. Use them wrapped in the @ sign, 
like this:

  htp = Wx::HtmlEasyPrinting.new('printing')
  htp.header = "Page @PAGENUM@ of @PAGESCNT@"

I realised after your message that the textile docs have mangled the 
formatting of this, so it's not at all clear. I'll correct it now, 
thanks for reporting it.

I don't know about compatibility between SLES and OpenSuse or whether 
you're able to install 3rd party rpms, but:

I don't think you need these packages if you're compiling and installing 
wxWidgets yourself. wxGTK should have everything you need in it.

Sorry, this error isn't familiar to me. But I was a bit surprised that 
your self-built version looks to be in /usr/lib - I would have expected 
it to be in /usr/local/lib or /opt/lib. Might be worth checking again 
what wx-config --libs returns, and that the wxRuby build is pointing to 
the right libs.

Perhaps you might post the first few lines returned when running 'rake' 
to build wxRuby, summarising the kind of build to be done and the 
classes that will be excluded (eg PrinterDC is always skipped on Linux).

I can find a few references to this error message on the web with 
wxWidgets and various other packages and software, but no decisive solution.

The fact that the error is occurring with GCDC makes me wonder if the 
problem is specific to that class. Did you build wxWidgets with 
--enable-graphics_ctx? If you didn't, you might try this - especially if 
rake is not reporting that support for GCDC, GraphicsContext etc is 
going to be skipped.

Message-ID: <674e40dd0811101559s62eaf564o13ce73b7bc59f749@mail.gmail.com>

Hi all and thanks to everyone working on this project =o)
I have a problem, and I suspect it has its origins in WxRuby...
In my program I use a GenericDirCtrl and handle its corresponding
TreeCtrl item selection event with evt_tree_sel_changed.
In the method handling this event, I try to get at the data of the
selected item, but I run into this:

./my_xrcise_frames.rb:43: [BUG] Bus Error
ruby 1.8.6 (2008-03-03) [universal-darwin9.0]

Abort trap

The code for the event handling method is as follows, where
gdc_browse_tree is the GenericDirCtrl instance:

def on_browse_tree_sel_changed(tree_event)
  item_id = tree_event.get_item
  raise 'item_id was zero' if item_id == 0
  tc = gdc_browse_tree.get_tree_ctrl
  item_data = tc.get_item_data(item_id)
  raise 'item_data was nil' if item_data == nil
end

The line number referenced in the crash bus error (43) is the
"item_data == nil" comparison. The exception doesn't get raised - the
application just crashes. I tried to reproduce it by catching the same
event by modifying the treectrl.rb sample, so I could send you code
you were already very familiar with, but the error didn't appear then.
It seems to require a GenericDirCtrl.

I'm running:
OSX 10.5
ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]
wx_sugar (0.1.20)
wxruby (1.9.9)

Any help is greatly appreciated! If I have omitted any important
information from this mail, tell me and I will do my best to provide
it. I have used wxruby with great results on linux, and I hope to be
doing the same on OSX in the future.

Best regards,
Mathias

Thanks for reporting this. I think it's a bug. In a normal Wx::TreeCtrl 
get_item_data works fine, but the item data held by a TreeCtrl 
associated with a GenericDirCtrl isn't a valid ruby object. We can fix 
this, and it would be helpful to understand what you were trying to do here.

Could you say what you expected to get from calling get_item_data here 
please? The GenericDirCtrl  already has methods (eg get_path, 
get_file_path) that will return the value of the currently selected 
directory.

BTW, it's very much appreciated if you can demonstrate a problem in a 
minimal, self-contained, runnable sample, rather than just a isolated 
snippet. That saves those looking into it having to guess how to 
reproduce the context of the problem.

thanks
alex

Thanks for the quick reply! I apparently misread the docs gravely, and
got the impression that I had to pick the selected path from the item
itself. GenericDirCtrl.get_path does exactly what I needed... Sorry
for wasting your time =o)

I read on the website about you preferring self-contained error
reproduction code, and I completely understand that. The only reason I
didn't do that was because I'm using XRC and xrcise, so (I think) it
would have been 2-3 separate files, in which case it would be easier
to file a bug in the tracker and put them there. I just thought I'd
find out if the problem was wxruby-related or not, first.

If you still want a little package of code reproducing the error, then
I'll absolutely cook it up, but you don't need to extend the bindings
for my sake anymore, since as you correctly suspected I didn't really
need the item data - and maybe no one else will either... =o)

Thanks again,
Mathias

NP, you haven't wasted my time at all. It helps the dev team understand 
where the docs could be clearer. As I said, thanks for reporting the 
issue; we can look into making wxRuby give more helpful error messages 
than crashing with a "bus error".

Simply from experience, taking a problem down to a minimal example is 
often a good way to figure out where the error is coming from.

Subject: [wxruby-users] can't subclass AuiDockArt
Message-ID: <19213b336c59649dff710d9375d7bdcd@ruby-forum.com>

Hi,

I'm using wxRuby with the Aui classes. Everything is fine (Manager,
ToolBars, Panes, ...) and now i want to override the default drawing for
the manager.

Thus I want to use #set_art_provider to give my implementation. When
doing that I receive a SWIG exceptions:

Expected argument 1 of type wxAuiDockArt *, but got DockArtProvider
#<DockArtProvider:0x3682e5c>
        in SWIG method 'SetArtProvider'

The DockArtProvider class (ruby class) inherits from AuiDockArt like so:
  class DockArtProvider < Wx::AuiDockArt
    ...
  end

Is something wrong on my side or on SWIG's one?

Hehe. It was a long time ago that I added the AUI classes, and in those 
days I wasn't very good at classes with virtual methods called from C++ 
into Ruby. And I thought "who would ever bother to define their own 
DockArt drawing in wxRuby?".

It's really nice to hear about people pushing the library and wanting to 
use these advanced features. If you could file a bug please, and attach 
a minimal sample with an AuiManager and AuiDockArt subclass with the 
needed methods defined, I'm happy to have a go at fixing it.

By the way, I think I took the same attitude to AuiTabArt, so if you 
would define your own AuiNoteBook drawing methods, please file that as a 
separate bug.

Great, I'll prepare that and submit a ticket.

Yes, AuiTabArt will be the next one, but just before I have 
AuiToolBarArt!
For the latter, I'm currently creating SWIG files for wxRuby because 
AuiToolBar and its AuiToolBarItem were not yet defined. I'll also submit 
them in a separate ticket (enhancement or the like)

Thanx for your support Alex.

Hello there

I'm working on a grid of many rows and one column
For example: if I want to show the name of the states, I only need their
names and nothing more, so the grid will be a many rows(number of
states) and one column(name).


The point is that I dont want the lavels of the rows on my left, I only
want the cell but no row names. I don't know if i'm explaining myself so
i'll paste some images (from google)

this is the grid with both row and column lavels:

end this is a grid with only the column lavel (no row lavels):

Simply, with a Wx::Grid

grid.set_row_label_size( 0 ) # or
grid.row_label_size = 0

But I wonder if Wx::Grid is the best control for this. Have you looked 
into Wx::ListCtrl (especially with the Wx::LC_REPORT style)? It will 
display a list of items with multiple text columns per item.

Alex, You did right with SWIG AuiDockArt.

My sample application was changing the constructor signature by having 
an argument in the ruby initialize method. When this happens, SWIG 
generated code detects it and throws an "type mismatch" exception (the 
one reported in the initial message). I've learned something today (that 
sounds very coherent!).

I'll still fill a ticket to have AuiDefaultDockArt available so we can 
simply subclass it to customize only one or two methods.

Best Regards,

Pascal.

Thanks for the report. It's strange. The constants are definitely there 
in the source files, but I also find TE_RIGHT and TE_CENTRE to be 
undefined (1.9.9, SVN HEAD on OS X).

To work round it for now, you can use the following constants which have 
the same value (in the C++ source, the TE_ constants are just aliases 
for these).

Wx::TE_RIGHT = Wx::ALIGN_RIGHT
Wx::TE_CENTRE = Wx::ALIGN_CENTER_HORIZONTAL

I don't think you need these packages if you're compiling and installing
wxWidgets yourself. wxGTK should have everything you need in it.

Sorry, this error isn't familiar to me. But I was a bit surprised that
your self-built version looks to be in /usr/lib - I would have expected
it to be in /usr/local/lib or /opt/lib. Might be worth checking again
what wx-config --libs returns, and that the wxRuby build is pointing to
the right libs.

Perhaps you might post the first few lines returned when running 'rake' 
to build wxRuby, summarising the kind of build to be done and the
classes that will be excluded (eg PrinterDC is always skipped on Linux).

I can find a few references to this error message on the web with
wxWidgets and various other packages and software, but no decisive
solution.

The fact that the error is occurring with GCDC makes me wonder if the
problem is specific to that class. Did you build wxWidgets with
--enable-graphics_ctx? If you didn't, you might try this - especially if
rake is not reporting that support for GCDC, GraphicsContext etc is
going to be skipped.

Seems this symbol comes from libmspack, which wxWidgets uses to support 
reading CHM help files. I don't know why this problem is occurring, but 
you could perhaps try excluding the feature.

Could you have a look at your setup.h file (somewhere like 
/usr/local/lib/wx/include/gtk-unicode-release-2.8/wx/setup.h )

and see if it has a line wxUSE_LIBMSPACK.

If the value of this is 1, you could try compiling wxWidgets again 
(sorry) configured with the additional option

If you want to have coloured, styled text using TextAttr, you must 
create your TextCtrl with the styles 
Wx::TE_RICH|Wx::TE_RICH2|Wx::TE_MULTILINE

A normal multiline TextCtrl is just plain text, in system standard colours.

Subject: [wxruby-users] How to refresh a panel?
Message-ID: <1e8335b08efebdd25e71d7bbde583e6d@ruby-forum.com>

Hello again

This time i have a problem with this code

Well, what i'm trying to do is, through a menu, to change panels.
The problem is that i can't find a way to change the panel, or refresh
or delete, or whatever should be done.

i've attached the the zip file with the runable code

the code is:
##on 'def initialize' of a Wx::Frame class
#@Panel=Panel.new(self)##If i initialize @panel here, it doesn't refresh
when the event is called
###end initialize

###event functions##
def cState(menu)##the function called from the event
      #@panel.destroy ## Error:  undefined method `destroy' for
nil:NilClass (NoMethodError)
      @panel=Test.new(self)##a WX::Panel class.
end
##the other function is similar to this one
###end event functions

if i'm doing the wrong way, please tellme, and if possible, post a link
to an example, tutorial or explanation. I'd be very thankful

Ramo

First off, have a look at whether a Wx::Notebook might suit your 
requirements. It's intended for combining different panels. It has 
methods for switching easily between pages.

If you want to swap panels, you probably just need to destroy the old 
panel and add in the new (see below)

I'm more used to doing this within a sizer-based layout, when it goes 
something like:

new_window = MyWindow.new(old_window.parent, ...)
old_window.containing_sizer.replace(old_window, new_window)
old_window.destroy

This keeps the layout consistent

Well one problem you have is that you call it @Panel here (with a 
capital "P") and @panel later.

Subject: [wxruby-users] GenericDirCtrl#re_create_tree behaviour
Message-ID: <674e40dd0811131750g72ece416i56878cd0849f455f@mail.gmail.com>

Hi

When GenericDirCtrl#re_create_tree is called in order to refresh the
tree with any possible changes made to the file system since it was
loaded, it doesn't re-expand all the tree items that were expanded
prior to calling re_create_tree. I'm working on a solution to note all
open tree items and after re_create_tree manually expand the items
that are still present in the tree.

My question: Is there a nice way that I've overlooked to make it
automagically re-expand previously expanded nodes after recreating the
tree? I'm on my way towards doing it manually, but since the
GenericDirCtrl's TreeCtrl actually re-numbers the items in the tree
during the recreation process, I'll have to do it by matching TreeItem
text strings, and it's starting to feel like a hack (in the ugly
sense).

Thanks in advance, and best regards!
/Mathias

Sorry, but wxWidgets doesn't provide a magic way to do this. As the name 
suggests it's a generic control (ie written from the ground up) so it 
doesn't benefit from the way that modern OSes update file dialogs etc as 
new files and directories are created.

However it's not hard to get a list of the currently open folder names:

      tree = dir.tree_ctrl
      open = tree.select { | item | tree.expanded?(item) }
      open.map! { | item | tree.item_text(item) }

Note that wxRuby creates the tree items as their parent is expanded, so 
this will only traverse whatever folders have been shown, not every 
possible folder.

I expect you'd also want to use the full paths as the unique keys:

      def tree.item_path(item)
        return "" if item == root_item
        path = item_text(item)
        while item = item_parent(item) and item != root_item
          path = "#{item_text(item)}/#{path}"
        end
        path
      end

I need to fix TreeCtrl#get_item_data for the trees from GenericDirCtrl 
as it currently crashes. It would seem sensible for the item_data to be 
or include the paths. So I'd be grateful if you could follow-up with any 
problems you encounter in this.

Doing the re-opening is left to you - you'll need to work hierarchically 
down the tree.

thanks
alex

Note that XRCise doesn't generate ruby code for the layout - but it 
writes all the boring code that loads your layout from XML. This means 
your handwritten classes can concentrate on event handling without 
having to write heaps of layout code.

Any probs, feel free to ask

Hi Alex,

thanks!

I prepared everything and started a test but it didn't work.
I created a xrc file and no used xrcise -o test.rm nonam.xrc and get the 
following error message:

Here the xrc xml:

Hello Heinrich,

What you will need to do, is goto your main Window form, and scroll down on
the properties page, you will see a field that says Subclass, and have a
semi-colon in it, with a + next to the field name.  You need to click that
plus, and put what name you want your ruby class to be named as.

EG:
MyFrame

This will tell XRCise when it generates the wrapper, that the class to use,
will be MyFrame.

hth,

Mario

The filename looks a bit suspicious to me. I would expect it to be a 
valid path rather than a mangled-looking URL. Hard to know where this 
came from without knowing more about your project layout.

I would check that you call xrcise with a relative path, in a typical 
project structure. Eg I have

app.rb
lib/*.*/rb
share/xrc.xrc

I call "xrcise share/xrc.xrc" from the base directory and that means 
that the paths resolve fine.

Hello,

here is my code. Is still can't get it to work.


# This class was automatically generated from XRC source. It is not
# recommended that this file is edited directly; instead, inherit from
# this class and extend its behaviour there.
#
# Source file: wxFormBuilder\nonam.xrc
# Generated at: Fri Nov 14 17:16:34 -0500 2008

require 'wx'
include Wx

class CometApplication < Wx::Frame

  attr_reader :m_statusbar1, :m_toolbar1, :m_textctrl1, :m_button2,
              :m_button3

  def initialize(parent = nil)
    super()
    xml = Wx::XmlResource.get
    xml.flags = 2 # Wx::XRC_NO_SUBCLASSING
    xml.init_all_handlers
    xml.load("wxFormBuilder\nonam.xrc")
    xml.load_frame_subclass(self, parent, "MyFrame1")

    finder = lambda do | x |
      int_id = Wx::xrcid(x)
      begin
        Wx::Window.find_window_by_id(int_id, self) || int_id
      # Temporary hack to work around regression in 1.9.2; remove
      # begin/rescue clause in later versions
      rescue RuntimeError
        int_id
      end
    end

    @m_statusbar1 = finder.call("m_statusBar1")
    @m_toolbar1 = finder.call("m_toolBar1")
    @m_textctrl1 = finder.call("m_textCtrl1")
    @m_button2 = finder.call("m_button2")
    @m_button3 = finder.call("m_button3")
    if self.class.method_defined? "on_init"
      self.on_init()
    end
  end
end

class MyApp < App
  def initialize()
    CometApplication.new
  end
end
MyApp.new.main_loop()

I start the code from C:\ruby\ruby_scripts\test.rb and the xrc file is 
in C:\ruby\ruby_scripts\wxFormBuilder\nonam.xrc

Try changing the line for the loading of the XML resource file from:

xml.load("wxFormBuilder\noname.xrc")

To:

xml.load("wxFormBuilder/noname.xrc")

Thankfully, to Ruby and wxWidgets, it doesn't really need you to use the \
slash to access a file path.

Often times, it's better to run xrcise as such:

xrcise -o noname.rb wxFormBuilder/noname.xrc

This way, doesn't matter if it's on Windows, or Linux, it will be able to
find the resources just fine.

You will need to convert the data over from Rmagick format to wxRuby
format.  You have the basic idea, in which you need to retrieve the RGB
Pixel data from the RMagick object, and then apply that to a wxRuby Image
object.  However, you will also need to grab the Palette from RMagick, to
apply to the wxRuby Image Object, through Wx::Image#set_palette().

I believe this is the method in which you need to go about this, however,
I've never worked with Rmagick, and wxRuby personally.  But you definately
need to go through Image#set_data() and Image#set_palette to make it work.
I think Alex may have a bit more experience with this, so he may be able to
give you a clearer answer to this question.

Hi all,

could the above errors be caused by a bug?

It's possible, but I can't tell without seeing the XRC file as well as 
the generated code. Please could you post your own script, the 
XRC-generated ruby file and the XML source file in a zip attachment, or 
file it as a bug with attachments on the website bug tracker.

set_data uses a raw, uncompressed format, but it looks like RMagick's 
to_blob method exports in known image formats.

I would use ruby's stdlib StringIO to create an in-memory representation 
that Wx::Image can read from.

require 'stringio'
str_io = StringIO( rmagick_img.to_blob ) # with whatever arguments are 
needed for to_blob
img = Wx::Image.read(str_io, Wx::BITMAP_TYPE_PNG) # or other image format

Then use Wx::Bitmap.from_image to get an object suitable for drawing on 
the screen.

> Is possible make scrollable StaticBitmap?
>   

Use Wx::ScrolledWindow to create a scrollable viewing for any contents, 
including Wx::StaticBitmap. There's different ways to use ScrolledWindow 
for which see the docs, but probably you could just use

scroll_win = Wx::ScrolledWindow.new(parent)
image = Wx::StaticBitmap.new( scroll_win, :label => bmp)
scroll_win.virtual_size = [ bmp.width, bmp.height ] # tell the window 
how big the whole canvas is
scroll_win.set_scroll_rate(5, 5) # scroll 5 pixels at a time, change as 
desired

Hi all,

I was able to solve the issue my self. It was a code issue in
class MyApp

this is how it should look:

class MyApp < Wx::App
  def on_init()
    Test.new.show()
  end
end

MyApp.new.main_loop()


Thanks to all!


bye
Henry

Subject: [wxruby-users] Xrc Q ;
	using mulitple layouts(Frames , dialogs , panels)
Message-ID: <bf2cd54407fcb8f8ca12cadd0e08d92e@ruby-forum.com>

Hi ,
  I am developing a simple GUI with wxruby. I am using wxFormbuilder to
get the xrc file.
  I need a simple Frame with menu item file and submenu open,save and
exit. And when I click on open(submenu) it should launch an
panel(dialog) which has filepicker.

 I believe I would be able to develop a dailog also under the same
project in wxFormbuilder(which it allowed without any warnings or
errors) ,when I run xrcise I get 2 classes under same xrc file. but when
try to load it when I click on open the applicaiton crashes.

 Can someone point to any sample program which uses multiple layouts
with xrc. What is the sequence of loading the objects .
Thanks
Jn

Hi

I'm running a short survey on GUI programming in Ruby. If you have a few 
spare minutes, please consider filling it out.

I'm not suggesting you all vote for wxRuby, but all the better if you 
have nice things to say ;)

Subject: Survey Invitation : Ruby + GUI
Date: Wed, 19 Nov 2008 22:43:29 +0000
From: Alex Fenton <alex at deleteme.pressure.to>
Newsgroups: comp.lang.ruby

Everyone's invited to take part in a short survey on using Ruby for GUI
programming; I'd be grateful for 5 or 10 minutes of your time at:

http://www.surveymonkey.com/s.aspx?sm=o2UwH3KcrOyLxKsh8mOJMg_3d_3d

Even if you never do GUI programming in Ruby, please take a minute to
respond, as it's interesting to know why people aren't using Ruby for
this as well as why people are. Non-GUI programmers get a very quick
version of the survey.

The survey should take no more than 5-10 minutes to complete. That's
unless you have a lot of things you want to get off your chest in the
comment boxes - which you're welcome to do too.

All the answers are anonymous. The survey will run for two weeks, after
which the results will be posted on the web, with a notice here. The
anonymised raw data will also be made available to those who are interested.

The background to this is that there are sporadic threads on GUI
programming on this group, but little overall picture of Ruby GUI usage
emerges. New options for GUI development have emerged in recent year.
I'm interested to know who's doing what, and how Ruby could be a better
language for these kind of applications.

Thank you to Rubyists who commented on earlier drafts of the survey.
Please feel free to forward the survey link to relevant mailing lists etc.

Thanks for your support.

Could you please post the error message that you get when you click on 
'open'? It's hard to know what's happening otherwise. Also please say 
what platform (eg Win XP) and version of wxRuby you're using.

Lastly, please show the code you've written to open the initial window 
from Ruby.

There shouldn't be any problem having any number of different dialogs 
and frames in a single project. I have one (using DialogBlocks) which 
has at least 10 separate top-level windows.

Problem 1
   I had overlooked the error, my bad.

./TestXrc.rb:69:in `find_window_by_id': Error wrapping object; class 
`wxFilePickerCtrl' is not supported in wxRuby (NotImplementedError)
  from ./TestXrc.rb:69:in `initialize'
  from ./TestXrc.rb:77:in `call'
  from ./TestXrc.rb:77:in `initialize'
  from ./TestWrapperClass.rb:7:in `new'
  from ./TestWrapperClass.rb:7:in `initialize'
  from TestApp.rb:12:in `call'
  from TestApp.rb:12:in `process_event'
  from TestApp.rb:12:in `main_loop'
  from TestApp.rb:12

   As wxruby does not support wxFilePicker, is there an alternative ( 
and FileDialog (Which I suppose I could have used, is not there on 
wxFormbuilder) is there any other alternative?

Problem 2.
  I put a textbox+button combo to work around the unavailablity of 
filepickerctrl. but now I am in a sort of design issue due lack 
understanding on how I can make the dialog a child of frame and from 
there I can catch its events

 Here is the design
    TestXrcWrapperClass << TestXrc(BaseFrame) and
    BrowseFileWrapperClass << Browsefile(OpenfileDialog)
    TestApp creats TestXrcWrapperClass which create 
BrowsefilewarraperClass.

  Q. How will I get the close events from dialog to the Frame?
  Q. How do I put it into a parent child framework(the Dialog and Base 
Frame). ?Is that a better way to go?

I'm using STAY_ON_TOP in the style when I create my Frame app so it is
always on top, and it works fine.  What I want, though, is for the Frame to
stay on top under some conditions, but behave normally under other
conditions.  I don't see any set_style method for Frame that would let me
turn the STAY_ON_TOP behavior on and off dynamically.  Is there any way to
do this?

 From my reading of wxWidgets discussions, there's no way to change the 
style flags of a Window (inc Frame) after it's been created. This is 
because changes are not guaranteed to be honoured on all platforms.

The way round this in your circumstance might be to have two frames, 
with one hidden and one shown at any time. One has the STAY_ON_TOP 
style, the other not. When you want to change the STAY_ON_TOP behaviour:

1) hide the currently shown frame
2) reparent that frame's top-level content (eg Panel) to the other frame
3) move the frame you're about to show to the same size and position
4) show the previously hidden frame

Thanks, but I just noticed that there is a Window#set_window_style_flag
which seems like it would do what I want.  I think I'll give that a try.  If
it doesn't work I might try your two frames solution.

Looks like Window#set_window_style_flag allows me to turn STAY_ON_TOP on and
off (in MS Windows).

Ah, thanks, I thought there was some method that did this but couched in 
warnings about changes to some flags on some platforms not being honoured.

Useful to know that this one is - much neater solution.

Subject: [wxruby-users] Static line is not drawn
Message-ID: <fcf5bddc39e96caa29681aade2fc26d6@ruby-forum.com>

Hello there,

My next problem is with a wx::StaticLine

ok, in the code, i'm using a notebook and i'm putting a panel in it. I
declare and initialize comboboxes, grids, lavels (static texts),
textctrl, buttons, etc, and a StaticLine.

Everything appears on the window, but not the line. If I call the line
outside the notebook in an independen panel (on other program) the line
is drwan. So I think I missed something.

Another problem is that the TextCtrl is drawn in a strange way: just a
white rectangle whithout borders and it looks bad.

I'm attaching the code, please run it and check what I mean.
Any help would be great!

I'm using Windows, and I've olny tried the code on windows.

Hello,

after installing wxruby-1.9.9-x86-mswin32-60.gem
i tried the grid.rb sample:

after changing the value in the checkbox and clicking on another row,
the following error is raised:


C:/Programme/ruby/lib/ruby/gems/1.8/gems/wxruby-1.9.9-x86-mswin32-60/sam

So i can not integrate this version in my production environment. My
actual version is wxruby-1.9.5

The alternative is to do what you've done below. In fact, this is what 
wxWidgets does anyway on Windows and OS X; the "wxFilePicker" is only a 
native control on GTK. This is the main reason the class isn't ported.

I'm not clear which dialog you mean, or where the FilePicker goes. If 
all you want to do is allow the user to choose a file to open (like an 
"Open" item in a menu), you don't need FilePicker. The simplest way is 
just to use Wx::file_selector function

evt_menu(Wx::ID_OPEN) do
  file_to_open = Wx::file_selector('Choose a file')
  # .... note that file_to_open will be an empty string if the user 
chose Cancel
end

For more control, use Wx::FileDialog - see the docs and the dialog sample.

dlg = MyDialog.new(self, ...)
dlg.evt_close { | evt | puts 'my child dialog has closed'; evt.skip }

But conventionally, modal (blocking) dialogs communicate the user's 
selection back to the calling frame through the return value of 
show_modal, eg:

dlg = Wx::FileDialog.newl(self, ...)
result = dlg.show_modal
if result = Wx::ID_OK
  puts 'you chose' + dlg.file
else
  puts 'you cancelled'
end
end

You should definitely make a modal dialog a child of the calling frame. 
I'd suggest you have a look at the dialogs.rb sample to see how it's done.

Thanks for the report. I think this must be the same bug as this:

http://rubyforge.org/tracker/index.php?func=detail&aid=21985&group_id=35&atid=218

I have a fix in the works but it will need recompilation.

If there is something critical you need from teh current release, you 
should be able to work around this by checking the class of the object 
coming into the event handler.

return unless event.kind_of?(Wx::GridEvent)

Subject: [wxruby-users] RFC on cleaning Wx::App
Message-ID: <1a113b726a84525f19d87aee84c9c9bf@ruby-forum.com>

Hi,

I added a missing feature in Wx::App that let's you handle in one place
exceptions raised in any event handler (without exiting the main_loop,
so that these exceptions may be not fatal to the app).

At that time I found that the docs of Wx::App and the code itself are
not in sync. I'm in the process of creating a ticket with a patch for
this.

Before I complete the patch, I request some comments on these methods:
  #on_fatal_exception
  #on_unhandled_exception
  #on_exception_in_main_loop

As these methods are designed to deal with C++ exceptions, shouldn't we
simply %ignore them in wxRuby? (That's my proposal)

Additionnaly, I found that App.i doesn't %include "wxApp.h" at all, the
class definition is inlined in App.i directly (at the end of file). So
should we get rid of "wxApp.i" ?

Regards,

Pascal

That would be good. Ideally something that would work ruby-ishly - eg 
rescue.

This discussion is probably better on wxruby-dev.

Yes.

Probably not - the header files in swig/classes/include work as a list 
of the classes available, even if some of them aren't used in building 
the wxruby library.

Hi all,

i am trying to use wxComboBox (instead of wxChoice) to capture
wxTE_PROCESS_ENTER event.

If i enable TE_PROCESS_ENTER flag on the resulting xrc file, i get an
'Unknown style flag wxTE_PROCESS_ENTER' on app loading.

Probably wxComboBox doesn't reconize this kind of event.

How do i catch this event for the wxComboBox widget?

Thank you all.

 Wx::TE_PROCESS_ENTER can be set programmatically by
window#toggle_window_style(Wx::TE_PROCESS_ENTER)

...now it works, but enabling this flag, the widget loose TAB controls (TAB
/ SHIFT+TAB)

To try it out, on the 'BigDemo -> wxComboBox' example if i add this flag

on line 23:

cb = Wx::ComboBox.new(self, 500, "default value", Wx::Point.new(90,50),
Wx::DEFAULT_SIZE,
                                sampleList,
Wx::CB_DROPDOWN|Wx::TE_PROCESS_ENTER)

i get the enter event but no tabbing is possible.

Is it a bug?

Thank you for your help.

The fact that setting this style when the control is created suggests to 
me that it's not really meant  to work like that, and I don't understand 
what you're trying to do here. Why do you want a ComboBox that processes 
ENTER?

I don't know. I expect if the control is told to consume ENTER, it also 
consumes TAB.

The problem lies in the fact, that Wx::ComboBox has a Drop down, and a Text
Edit in it.  I believe that Fabio wants the Enter event, so that he can add
what a person enters into the Drop Down, if I am understanding correctly.
The best thing to do, is to monitor evt_keypress, and create a new item, and
update that item in the combo box, as the person types stuff into it.
Either that, or monitor on focus lost, and check to see if the item is in
the combo box, if not, add it.  Though, that can lead to it's own problems,
as a person could switch between the controls several times, and have
several items added if he changes the text each and every time he tabs
between the controls.

Just a couple of suggestions on how to work around it.

Hi Alex & Mario,

i am working on an invoice form, where the user should be able to fill
fields using mainly tab, numeric keys and confirm by enter on every field
he's working on. The basic reason for that, is the user should only type on
the keyboard avoiding as much as possible using mouse for speed reason.

Basically i use Enter to validate user input

Is ComboBox able to trigger keypress event??

The above user inserts hundreds of products a day and he knows exactly what
vat code to use for that kind of product, without having to choose from a
dropdown menu. The ENTER is to confirm what he typed.

ComboBox let you do that quite well standardizing behaviour between fields.

Unfortunately, on ComboBox, if you enable enter you loose the opportunity to
use the tab

thank you both.
