Question

How can I detect whether a double click on a QWidget (QStatusBar, in my case) occured while a modifier key was held down?

I can overload void QWidget::mouseDoubleClickEvent ( QMouseEvent * event ) to get the double click, but how can I sure whether the widget receives the key events when it might not have the focus?

Answer 1

I found the answer:

QMouseEvent is derived from QInputEvent and that has a method called modifiers():

From the Qt documentation:

Returns the keyboard modifier flags that existed immediately before the event occurred.
