Passing all mouse events from child to parent

[Desperado17]

I have a QWidget with a layout where I add QWindow subwidgets created by
QWidget::createWindowContainer.
I want all mouse events to be processed by the parent.
Currently I have to override the methods in the QWindow derived class and explicitly send them to the parent, bus is there a simpler method to cover all events?

you can use eventFilters for such a task:

Thanks, I'll have a look at that.

For some reason it seemed to work out of the box for regular QWidget types, is this normal?

Ok, I now tried calling childWidget->installEventFilter(this) in the constructor of the parent widget. Also on the wrapped window directly. The parent does not receive events.

[Desperado17]

QWidget doesn't really implement eventFilter method, right? Is implementing it on the parent and then just calling event() the right way?

Apparently the QWindowContainer that createWindowContainer creates does receive the events the wrapped QWindow receives out of the box. Does anyone know how this class does it?
