Which is exactly what we do because we need to know *before* a window is
minimized:
void IgorNormalWindow::showEvent(QShowEvent *event) {
QWidget::showEvent(event);
emit windowVisibilityChanged(this, true);
TellIgorWindowStatus(this, WINDOW_STATUS_DID_SHOW, 0);
#ifdef MACIGOR
if (!igorNSWindowNotifier)
{
if (!IgorApp()->IsMDI())
{
igorNSWindowNotifier =
CreateMinimizeNotification(reinterpret_cast<void *>(effectiveWinId()),
reinterpret_cast<void *>(this));
SetNSWindowParticipatesInCycle(this, false);
}
}
else
{
if (IgorApp()->IsMDI())
{
DeleteIgorCocoaWindowNotifier(igorNSWindowNotifier);
igorNSWindowNotifier = NULL;
}
}
#endif
}
The CreateMinimizeNotification() function wraps Objective C++ code that
ultimately does this:
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(handleMinimizationNotification:)
name:@"NSWindowWillMiniaturizeNotification"
object:cocoaWindow];
