this signal will generate whenever anything on customContext Menu changed, i want the signal only for select all.
whenever context menu select all is enableed, i want to enable edit menu select all, when ever edit menu select all is disabled, i want to disable edit menu select all. How can ii do it, please suggest me any idea?

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.
