It is still no effect,I forgotten to say something,when i switch to a new widget ,I must press a control to activate the key event ,even press on the other part of the widget,it still no effect.But I can sure the problem is the widget isnt get the focus or activate,but i have no idea to solve it.Do you think the problem due to the eventFilter written in the base class?
