maybe:

QWidget(destWidget && destWidget->parentWidget() ?
	 destWidget->parentWidget() : destWidget)

that way if the destWidget has a parent, it gets used ... otherwise it's 
parented to the destWidget (or null if destWidget is 0)...

that would keep the behaviour the same for objects that have a parentWidget(), 
but add a nice fallback.
