Bug for setting application's default cursor
Reported by lyle (at lylejohnson) | November 11th, 2009 @ 10:23 PM
A user was attempting to change the DEF_MOVE_CURSOR. This code worked:
FXApp.new do |app|
app.setDefaultCursor(DEF_MOVE_CURSOR, FXCursor.new(app))
...
end
but this code did not:
FXApp.new() do |app|
app.setDefaultCursor(DEF_MOVE_CURSOR,app.getDefaultCursor(DEF_ARROW_CURSOR))
...
end
The latter example crashed with the following message:
abnormal program termination
Kory.rb:1320: [BUG] Segmentation fault
ruby 1.8.4 (2005-12-24) [i386-mswin32]

A workaround would be to set the DEF_MOVE_CURSOR back to nil in your program's exit handler. The problem is that FOX is trying to double-delete the same cursor object (the one that both DEF_ARROW_CURSOR and DEF_MOVE_CURSOR refer to).

FXRuby is a library for developing powerful and sophisticated cross-platform graphical user interfaces (GUIs) for your Ruby applications. It’s based on the FOX Toolkit, a popular open source C++ library developed by Jeroen van der Zijp. What that means for you as an application developer is that you’re able to write code in the Ruby programming language that you already know and love, while at the same time taking advantage of the performance and functionality of a featureful, highly optimized C++ toolkit.
