Question

In a Qt application, I have a bunch of automatically-created QActions (menu items) that I add to a menu in the menu bar. Each opens a different file. I’d like to connect them all to the same slot so as to not write the same code many times. From that slot, though, how do I figure out which of the QActions was triggered?

(Example: In Cocoa I’d do this with the sender parameter in the action selector.)

Thanks!

You have two options:

• Call sender() in the slot, which will return the action that triggered the signal.
• Use QSignalMapper.
