How to block action in menu in QT?

Question

Qt

Hello!!!
Tell me how to block the action in the item in the menu? I know direct blocking
ui->actionMyaction->setEnabled(false);
, but I have a connection with the slot and inside this slot it is necessary to make the menu item inactive.
через QObject::sender()->objectName();
I get the name action and then how to refer specifically to the action that sent the signal is not clear

Answer 1

if (auto action = qobject_cast<QAction*>(sender())) {}
