Hello,

Using gtk3 on window, i get a bug (program scratch)  
when resizing window (specially on resizing dialog window), with almost  
all my Ruiby applications.

Here a scratch with an old gtk demo :

…\gtk3-2.0.2-x86-mingw32\sample\misc\>ruby dialog.rb

dialog.rb:14:in `new’: ‘Gtk::Button#initialize(label\_or\_stock\_id,  
use\_underline = nil)’ style has been deprecated. Use

…many deprecated…

\*\*  
GLib:ERROR:gmain.c:3057:g\_main\_dispatch: assertion failed:  
(current-\>dispatching\_sources == &current\_source\_link)

This application has requested the Runtime  
to terminate it in an unusual way.  
Please contact the application’s  
support team for more information.

I got a related report. It seems that GTK+ 3 that is bundled  
in gtk3 gem may be broken. (It is built by me on my Debian  
GNU/Linux.)

The problem may be solved in the next release if I can build  
GTK+ 3 Windows binary on my Debian GNU/Linux. Could you try  
old gtk3 gems to find which version works well or doesn’t  
work well? I know all gtk3 gems are broken or gtk3 2.0.2 gem  
is only broken.

You can install and use old gtk3 gem by the following:

> gem install gtk3 --version 2.0.1  
> type test.rb  
> gem “gtk3”, “= 2.0.1”  
> require “gtk3”  
> …  
> ruby test.rb

You can find all available gems at

“x86-mingw32” platform gems are for Windows.

## Thanks,

kou

Hi,

I confirmed it, too.

“GLib.prepend\_environment\_path” was changed to “GLib.prepend\_dll\_path”  
since glib2-2.0.0.  
It works if using the same version gems.

e.g.)  
gem “glib2”, “= #{ARGV[0]}”  
gem “atk”, “= #{ARGV[0]}”  
gem “gdk\_pixbuf2”, “= #{ARGV[0]}”  
gem “pango”, “= #{ARGV[0]}”  
gem “gio2”, “= #{ARGV[0]}”  
gem “gdk3”, “= #{ARGV[0]}”  
gem “gtk3”, “= #{ARGV[0]}”

However I found a workaround. If you hurry, please try this:
