...Without calling refresh, things seem to be fine. (Although obviously my app doesn''t display the changed state.) With the refresh, I get: mainframe on_paint ./View/mainframe.rb:79:in `clear'': in method ''Clear'', argument 1 of type ''wxWindowDC *'' (ObjectPreviouslyDeleted) from ./View/mainframe.rb:79:in `on_paint'' from ./View/mainframe.rb:78:in `paint'' from ./View/mainframe.rb:78:in `on_paint'' from ./View/mainframe.rb:29:in `initialize'' ... Anyone have an idea of what might be going on? Is there a...

Hi all, I''m currently writing a simple outliner application as a tutorial on wxRuby (both will be soon released ;-) ) I tested this application on Windows and Linux and found that the tree event behavior : - is sometime strange on each platform - is also different on each platform Even if I managed to take care of these differences in the application, I''m just wondering if : -

When implementing EVT_PAINT handlers in c++ the PaintDC object is constructed at the beginning of the function, and auto destructed at it''s end, which informs wxwidgets that "invalid regions in the window have been repainted". Under ruby, this is not the case and causes a stream of EVT_PAINT events to be sent to the given window (until one of PaintDC objects is destructed by

Hello all, i''m using wxruby 1.9.4 with Grid and the model class: "GridTableBase" like in the code below. But the method set_table of the grid does''nt work. Can anyone help me? require ''wx'' include Wx class MyGridTableBase < GridTableBase def get_attr row, col, attr_kind ## end def get_number_rows 0

Attached is a patch and some extra files to fix our ObjectPreviouslyDeleted crasher with the paint method. As discussed, it just re-implements the method in Ruby. I created a directory lib/wx/classes as a place to hold Ruby extensions to the API. The attached app.rb and window.rb files should be added to it. When this patch is applied, files in that directory are aut...

...e little pane (eg Wx::Choice) - calendar.rb OK - caret.rb OK - but arrow keys don''t work properly (should they?) - controls.rb Seems OK, except doesn''t work if not run from current dir. Probably should add textctrls to this one. - dialogs.rb Problems with DC - seems to cause ObjectPreviouslyDeleted error in an on_paint handler. I have worked round this.

I think (cautiously) that recent commits have at last fixed the memory management for most/all the currently ported classes. I get ObjectPreviouslyDeleted exceptions on exit occasionally in bigdemo, but that''s about it. If I never see a C debugger again it will be too soon. Bugs on the tracker are either minor OS X-specific quirks, which I can''t tackle at the moment, and a couple of method-specific bugs which I am currently stum...

Hi Just a quick update on memory leaks etc. I''ve just dropped a bunch of patches with a new approach to linking ruby''s GC to Wx''s memory handling. Still some work to do - eg bigdemo.rb falls over quite quickly - but working well for me on other samples. Briefly, it disposes of fixdeleting. For almost all objects that aren''t Windows, they should now be
