pure virtual method called
« on: January 12, 2007, 04:11:05 am »
Settings -> Editor -> Keyboard shortcuts, I need to remove Ctrl-Space which be used to complete code. But after doing that and exit Code::Blocks, I got some errors like this:
>pure virtual method called
>terminate called without an active exception
>忽略 (core dumped)

kubuntu 6.10
Nightly builds CB_20070108_rev3466_Ubuntu6.06.deb

Thanx and forget my poor english.

I can't reproduce this here with revision 3479 on gentoo Linux (wxGTK 2.6.2, gcc 4.1.1).

I found the error message "pure virtual method called" was disappeard after I use the version 3480 which by checkout and compile/build, although I can't remove the keyboard shortcut "Ctrl+Space" which used to "Code Complete". and I found there is a bug: Open Settings -> Editor -> Keyboard shortcuts, choose any selection in the Command Listbox. for instance, select File -> open. after that, click the highlighted item from Current shortcuts Listbox, will change it to unselected state. The core dump will be occured by click Remove Button right now.

Yes, I can reproduce this one. Here is the backtrace for this crash:

Edit:
I think I found the problem and already have a patch. I could not test it yet but if it works I will post it here and probably upload it to berlios.

OK, I found and solved the problem and posted the patch at berlios. (Look here.)

Although keybinder tries to disable the remove button whenever there is no shortcut selected it fails in one situation: If someone just deselects the selected shortcut the buttons are not updated because deselection an item does not create an event, or at least not the EVT_LISTBOX event (and there seems to be no other event that could be generated in this situation). That way the Remove-button stays enabled. Then if you click it wxKeyConfigPanel::OnRemoveKey will be called with an invalid parameter. My patch simply adds a check to the event handler for the button which checks if there is any shortcut selected. If yes it calls wxKeyConfigPanel::OnRemoveKey as usual, if no it simply returns and does nothing. I tested it here with revision 3479 and it seems to work.

Fixed SVN 3482

I'm unable to reproduce the described Ctrl-space problem either on MSWindows or andLinux.

I added Ctrl-space to the "About" menu item. It also deleted ok.
