why does my keyEvent activate after mousepress

[mike king]

Maybe.
Hard to tell since you didn't post the actual code of your event filter.

Have you tried with proper key event handling in the base class instead of resorting to a filter?

you meant I write a keyPressEvent() in the base class? But if the KeyPressEvent written in the base class, can the event deliver to the widget from the control,because the event be filtered after the eventFilter,firstly delivered to the relate control,not to the widget.

Yes. You said that all your page widgets had the same base class.

You need an event filter if you need to keep events reaching their actual destinations or if the destination consumes them but you need them as well.

Maybe that is the case for you.
