CELayoutEditor keyboard not working under wxGTK

Postby iWerner » Tue Nov 23, 2010 10:59

Hi all,

When you run the CELayoutEditor in a wxGTK environment (I'm using v0.6.3 of the layout editor on Fedora 12) the EditorCanvas does not receive keyboard events, so the 'wasd' keys that moves the widgets as well as the 'g' ("snap to grid") key does not work.

The problem can be easily solved by handling an EVT_ENTER_WINDOW event and calling the SetFocus() of the wxGLCanvas in the handler.

This post describes the problem and its solution: http://old.nabble.com/wxGLCanvas-Key-events-broken-with-2.8--td17232036.html

I've created a patch that resolves this issue, which I've attached below:

It can be applied by typing patch -p1 -R < ../keyboard.patch in the CELayoutEditor-0.6.3 directory where you untarred the source code.
