search for: set_item_data

Hi, I have used set_item_data with ruby objects (an array) and got a crash. The reason is simple, the objects were deallocated by the GC. The easy solution would be to accept only long parameters (like the original interface). The hard is to play by the GC''s rules and increase the reference count and decrease on delet...

The attached fixes set_item_data, get_item_data and some other methods for the TreeCtrl so they work nicely with Ruby objects and GC. In C++ Wx TreeCtrl item_data works differently from client_data in classes derived from ControlWithItems (eg Choice, ListCtrl). A one-to-one mapping of the way TreeCtrl works would mean that you...

...e able to provide user data? to do this: ch = Wx::Choice.new() ch.append("pluto", 10) ch.append("pippo", 20) ch.append("paperino", 30) instead of this (the way i''ve found to get the same result): ch = Wx::Choice.new() id = ch.append("pluto") ch.set_item_data(id, 10) id = ch.append("pippo") ch.set_item_data(id, 20) id = ch.append("paperino") ch.set_item_data(id, 30) thank you. fabio. _______________________________________________ wxruby-users mailing list wxruby-users@rubyforge.org http://rubyforge.org/mailman/listinfo/wxruby-...

Hi I saw from the ChangeLog that [get|set]_client_data was removed from ComboBox for 0.4.0 because the methods weren''t working properly. TreeCtrl#get_item_data still seems to be there. I was wondering if someone who understood the issue could say if TreeItemData might also be afflicted with the same problems? I seem to be segfaulting quite a bit (actually, on TreeEvt#get_item), but it

so I''ve been using wxruby for a bit, and I have some questions. Before I start, I do want to say, that I am really liking wxruby, these questions are a result if really putting it through it''s paces. 1) how do you assign accelerator keys? this kind of works if I add a menu item like "&New\tCtrl-N", but this only works for commands in the menu, and for some
