mousePressEvent() not called on a disabled QCheckBox

Question

I'm trying to subclass QCheckBox to make it pass mouse clicks through if disabled. When my checkbox is not disabled (isEnabled() is true), Qt calls its mousePressEvent() as expected. When it is disabled, calls do not happen. Any ideas how to outmaneuver it?

What you describe is indeed the documented behavior. If you look at the source code, you will see that QWidget::event only calls mousePressEvent if the widget is enabled.

As a solution, you may override event instead of mousePressEvent(QEvent *e) and check if e->type() == QEvent::MouseButtonPress.
