[Fxruby-users] Error: FXRbGetRubyObj(this=0x084e7fb8) returns non-Qnil

[Hal F. <ha...@hy...>]

I've been rewriting my tree logic and it's much cleaner and
shorter now.

I subclass TopicItem < FXTreeItem and TopicTree < FXTreeList --
then I override addItemLast to create a TopicItem; and then call super
with that item; and then return the item.

But I'm getting an error every time I click a tree item (see
subject line). The object id differs.

Partial code below. (For the whole thing, see tycho.rubyforge.org
and run mkdata.rb first.)

However, it all works fine besides the error message, EXCEPT
that it segfaults when I hit the Quit button.

Ideas???

Thanks,
Hal





class TopicItem < FXTreeItem

   attr_accessor :dir, :path, :title, :notes

   def initialize(dir,path,title)
     super(title)
     @dir, @path = dir, path
     @notes = []
   end
