Deactivating common shortcuts
Message 1 in thread
Hello,
How can I deactivate common shortcuts such as Ctrl + A (which selects all
editable text on the focused widget) and Ctrl + V (which pastes stuff)?
The shortcuts described work on Windows and have their equivalents on other
OS.
I'm trying to make a customized QLineEdit that detects key press events and
sets it's contents according to which keys are currently pressed but
whenever I hold Ctrl and then press the A key it isn't detected and the
whole QLineEdit text is selected instead.
What I want would be something like disabling the widget, but in a way that
the widget continues to receive and send key events.
Thanks in advance.

Your code needs to intercept the Ctrl+A event before the QLineEdit code. Have
a look at this piece of documentation:

The event filter should help in this case.
