Bingo! I just reviewed a couple of old checkouts of Crystal Space I have, and it looks like some one "cleaned up" (i.e. broke) the plugin.
I orginally had a function:
void csGLCanvas::OnEnterWindow( wxMouseEvent& WXUNUSED(event) )
{
SetFocus();
}
Which fixes precisely the keyboard focus problem by giving it "focus
on enter" behavior.
Someone changed it to:
void csGLCanvas::OnEnterWindow( wxMouseEvent& WXUNUSED(event) )
{
csRef<iEventNameRegistry> enr = CS_QUERY_REGISTRY (g2d->object_reg,
iEventNameRegistry);
g2d->EventOutlet->Broadcast(csevFocusGained(enr));
}
The problem is, this tells Crystal Space has focus, but doesn't change
the *system* focus, which was the whole purpose of calling SetFocus().
Someone misread the purpose of the method and... broke it.
So, try re-adding SetFocus() to the csGLCanvas::OnEnterWindow() method
(in CS/plugins/video/canvas/wxgl/GLWXDriver2D.cpp).
