According to the documentation
wxNotebook::SetSelection() should return the previous
selection... (Like wxMSW does) but the wxUniv version
returns the currently selected selection.
Patch was tested with wxX11.
Applied patch [ 597313 ] Popup menu still used after deletion
By Hans Van Leemputten (hansvl)
- This patch exists out of 2 parts;
Part 1 is a patch to show the problem with the menu
sample (this part is just to show the problem and should
not be put into CVS!).
Part 2 is the fix and should be put in CVS.
(src/univ/menu.cpp)
- Instructions to reproduce the problem with the menu
sample:
1. Apply part 1 of the patch only.
2. Run the sample after recompiling it.
3. Press "Close Test" -> "Close", this will basically
remove the current menu bar and recreate it again and
re-use the menu item "Close test" from the old menu
bar...
4. Again press "Close Test", doing this will already
crash the sample.
- The cause of the problem is that the m_popupMenu in
wxMenu is deleted because it is a child of the old menu
bar (Note: it does not get destroyed by the wxMenu
destructor, but by DestroyChildren()) and m_popupMenu
is not put back to NULL when this happens...
- This patch was tested only with wxX11.
