What Can Block Mousepressevent Or Event Filter Mouse Click Events?

I can't seem to get any mouse clicks in a QTreeWidget. I have tried... ...overriding mousePressEvent, but it never runs at all. Not even to log a message. ...using an event filer.

Solution 1:

because what you can see (and click) on QTreeWidget is actually it's viewport(). You sholud install event filter on it's viewport() instead.
