Dear all,

I had a problem on a custom widget, where reimplemented dragEnterEvent and
dropEvent were properly called, but dragLeaveEvent was never called.

The event handling function were reimplemented in a "LinkWidget" class, and
then a ParameterWidget::LinkRefWidget was subclassing LinkWidget.

After many tries for making a MCVE, I figured out that un-nesting
LinkRefWidget was solving the issue.

Is this a bug, or is nesting QWidget subclasses officially unsupported?

Thanks!
