Qt multiple key combo event

Question

I\'m using Qt 4.6 and I\'d like to react to multi-key combos (e.g. Key_Q+Key_W) that are being held down. So when you hold down a key combo, the event should be called all t

Answer 1

QShortcut does not support the functionality you're looking for. You can only make combinations with modifier keys like Shift, Ctrl, Alt and Meta.

What your code does is to make a shortcut that responds when the user first presses W and then D. This is also why it will conflict with other shortcuts that respond to just W.

When you want to do something when both W and D are pressed at the same time, you'll have to override QWidget's keyPressEvent and keyReleaseEvent methods in order to keep track of their pressed state, and manually call your handler function once they are both pressed. If you don't have a suitable QWidget subclass in use you'd either have to introduce it, or install an event filter in the right place using QObject::installEventFilter, possibly on your application object if it's supposed to be a global shortcut.
