QAction doesn't do any rendering either but still has visble and enabled.

I've always used this to set the respective state on only one object (the 
action) and have all UI delegates (menu entry, toolbar buttons, etc) follow 
that automatically.

Obviously it is easier in QML where you can bind the enabled property of the 
menu entry, the toolbar button and the shortcut to the same custom property.

Do you have a specific use case in mind that would require to disable some 
trigger sources but not all?
