Qt: how to make an action with a non-working hotkey?

Question

Qt

We have a QTableView.
There is a key written directly in it - for example, Ctrl + A.
I want to push this command into the local menu, with the corresponding hint key: "Select all / Ctrl + A".
But this should only be a hint: Ctrl+A should not work if another component is selected. A command given through the local menu should always work.
How to implement?

Answer 1

Make your own menu, and use aboutToShow() to change the menu itself depending on the state.
