FXTreeList-App crashes

Jörg Abelshauser

My FX-Application crashes, when I update an FXTreeItem-Icon in an
FXTreeList (setopenIcon / setClosedIcon) with an event-method
(right-mouse-click).
Does anybody have an idea ?

Run it with regular ruby.exe instead of rubyw.exe (if on Windows) to get
some details about the crash?

not really helpful:
FxGui.rb:547: [BUG] Segmentation fault
ruby 1.8.2 (2004-12-25) [i386-mswin32]

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

Further, here is the code-snippet, which is called when
right-mouse-click at an tree-item:

item = @tree.getFirstItem

if @toggle != 8
@tree.setItemText(item, "Bla")
icon = makeIcon("testnode.ico")
@tree.setItemClosedIcon(item, icon)
@toggle = 8
else
@tree.setItemText(item, "Boing")
icon = makeIcon("testnode.ico")
@tree.setItemClosedIcon(item, icon)
@toggle = 7
end

...has helped ! Thanks a lot!
but it's not obvious from the docs. Whats's the difference between the
constructor and the create-method, the 1st icon , which i commit to the
item doesn't need the create-method ???

When you initially create the application, all children of the app are
created automatically.
If you add any new children after the initial App.create and you attempt
to access/display them, they have to be created, which you have to do
manually. I made this mistake before too.
