use QWidget::customContextMenuRequested() and QWidget::actions() to manipulate the state of actions or build your own menu inside that function.

I am beginner of Qt. can you please tell me ,if use customContextMenuRequested(Qpoint) as a signal, it is required to write our own function for slot or any default function is available?

If you need to process something custom - you have to add your own slot where you will do that and connect the signal to your custom slot.
