Hi Lyle,

Thank you for the excellent observation!

Adding a create did the trick. Now the code is working fine.

Hi!

Thanks to Lyle's pointer - .create method has solved the pane creation
problem. But there are other problem - how do I get rid of the pane.
Multiple calls to this class keeps stacking the pane over the old one.

In C++, I would have destroyed the old object - what do I do in FXRuby?

vPane.hide - looks to be a work around; but I think this will keep the
old objects in memory. Please suggest a good way to close the screen.

Try using removeChild with the pane's parent.

The steps should be roughly as follows:


	1) change the contents of the window (dialog box or toplevel window).

	2) compute the new size, based on layout parameters and sizes of the
	   widgets; use the topwindow's getDefaultWidth() and getDefaultHeight()
	   See footnote.

	3) Change the toplevel window's size according to the values computed
	   in step 2, calling resize() on the topwindow.  Note, the borders will
	   be added by the interface between FOX and your windowmanager.


The resize() will lead to a new call to layout(), since the window will have changed
size.  This will also result in a bunch of repaint messages which your program must
be allowed to handle before the window will be properly drawn to the screen.


Hope this helps,


			- Jeroen


Footnote: the size computed by getDefaultWidth() and getDefaultHeight() will be the
minimum fit of the window around its contents.

That is correct.  Drawing will get done only when the system gets to an
event loop, and processes out-standing redraw events.

To get it to do this BEFORE your callback returns, you must recursively
enter the event loop (presumably, block further user input while in that
subloop and only process non-input type events).

The good news is that this is possible: runModalWhileEvents() is what
you want to call; I suggest calling it during a long-winded file I/O
operation as well, so the screen has a chance to refresh.

The idea is to handle a bunch of events until the event queue is empty, and
then return to the the file import code.  You can invoke runModalWhileEvents()
repeatedly, if there is a reason to assume more events have arrived that need
to be handled.

When you first popup a dialog, there is a lot of back-and-forth between X11
server and the application, to resize and redraw items just put on the screen;
after that bunch of events has been handled, things kind of come to a rest and
the window is ready for business.

Note, it works better in FOX 1.7 because this function now as a parameter
to block for a little while, prior to returning with an empty event queue.

The suggestion from Meinrad Recheis is good too, but this is definitely more
complex; but multi-threading may be overkill for this particular situation.

The flaw in the original runModalWhileEvents() was to return when the event 
queue was empty.  The newer version in FOX 1.7 has a timeout parameter, which
allows it to wait a little while before giving on an empty event queue.

This is better since event queue being empty on the client side doesn't mean
the event queue on the server-side is empty yet...

Hello,
when I quit the application I'm currently developing there is a lot of
messages popping up (see below). I've not discovered any problems when
running the application, but have I done something wrong? Since ruby
1.9 is much faster I don't think 1.8 is an option for me anymore.

I don't think you're doing anything wrong. It doesn't seem to happen  
on every FXRuby app, but I too have seen it crash on exit (from Ruby  
1.9.1) in several cases, e.g.

	http://rubyforge.org/tracker/index.php?func=detail&aid=24073&group_id=300&atid=1223

It's been awhile since I've had time to look into this (or much else  
FXRuby related), but IIRC the problem boils down to the more or less  
random way that garbage collection occurs during finalization on exit.  
While your program's running, if you (for example) destroy a parent  
object, FOX will subsequently destroy the child object(s), and the  
Ruby objects associated with them get cleaned up in an orderly  
fashion. When the Ruby interpreter is exiting, however, it is possible  
that the child object will be GC'd before the parent, leaving dangling  
pointers lying around. I'm not really sure how to fix it at this point.

Fox doesn't handle accelerators correctly at shutdown and it causes lots of crashes:

Try calling this function in a SEL_CLOSE handler for your main window:

  def initialize
    ...
    self.connect(SEL_CLOSE, method(:cleanup_menu_panes))
  end

  def cleanup_menu_panes |sender, sel, data|
    ObjectSpace.each_object(FXMenuPane) do |object|
      children = []
      object.each_child do |child|
        children << child
      end
      children.each do |child|
        object.removeChild(child)
      end
    end 
    0
  end

Subject: [fxruby-users] FxRuby 1.9 Binary Gem?
Message-ID: <744437777@web.de>

Hello!

I am a beginner to Ruby but i like it very much. After installing the One-Click-Installer Version 1.8.6 i was very happy- everything worked finde. But i had update to version ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32] because of Look-Behinds in Regular Expressions.

But now the FxRuby Gem installed just fine but doesn't work anymore- I got an error, that msvcrt-ruby18.dll is missing (the old one from ruby 1.86 doesn't work). After searching the Internet i know why: FxRuby's Source is compatible to 1.9 but the binaries are for the one-click-installer Version. So the howto mean's i have to compile Ruby and FxRuby ... As a beginner this is a lot of confusing- I get some errors and i don't know which version of visual c++ i should use and so on. On the other side I shouldn't use the mswin32 version of ruby, because it's changing to mingw32. Here i also get a lot of errors installing and try compiling with MSYS, MGWIN.

For WxRuby there is a special 1.9 gem available- works fine. But i want to use FxRuby. Is there a way to get a FxRuby 1.9 Binary Gem for Windows? Don't get me wrong, but i spend hours of searching informations about these problems- that's not the Ruby Way, especially for a beginner it's very confusing and time intensive. A FxRuby 1.9 binary gem would be perfect.

Thanks in advance,
Dirk

Hi still very new but...

this line here one = FXText.new(wiz.container, :opts => LAYOUT_FILL)

to me says fill the window so wouldn't your button disappear?

I do stand to be corrected by my betters (ps i use foxGUIb for the GUI placement so maybe ignore my posting here.

dave.

Thanks Lyle for helping me with my other question.
Now I have a new one because it runs counter to what I think the docs are telling me.
Here is the code...
require 'rubygems'
require 'fox16'
include Fox

app = FXApp.new
wiz = FXWizard.new(app, 'wiz', nil, :width => 640, :height => 480)

wiz.cancelButton.connect(SEL_COMMAND) { exit }

one = FXText.new(wiz.container, :opts => LAYOUT_FILL)
one.text = "Some useful information here"
two = FXButton.new(wiz.container, 'a big ole button', :opts => FRAME_RAISED|LAYOUT_FILL)

wiz.finishButton.connect(SEL_COMMAND) { exit }

app.create
wiz.show(PLACEMENT_SCREEN)
app.run
It seems that when I add attach a command to the wiz.finishButton, when the time comes for it to appear (on the last panel) it disappears...
