Pretty dumm ;-) At a quick look, it looks to me like wa_ptr (work area
pointer?) is a hack. Also at a quick look, it means that QWorkArea is
effectively a singleton class. Ie, there can be only one instance of the
class in existence. The primary usage of wa_ptr is here:
bool lyxX11EventFilter(XEvent * xev)
{
switch (xev->type) {
case SelectionRequest:
lyxerr[Debug::GUI] << "X requested selection." << endl;
if (wa_ptr)
wa_ptr->selectionRequested();
break;
case SelectionClear:
lyxerr[Debug::GUI] << "Lost selection." << endl;
if (wa_ptr)
wa_ptr->selectionLost();
break;
}
return false;
}
