Is there a way to assign a KeyPressFcn to a button in matlab app designer?

2 views (last 30 days)
I am working on an app that has a drag and drop GUI, where I can create buttons the represents components of a system and drag them across the panel. I would like to be able to assign key commands that work while the components are being dragged, but the problem is that while dragging the focus is on the button, so the KeyPressFunction won't be activated.
I tried to maintain focus on the UIFigure with
figure(app.UIFigure)
at the end of the dragging function, but since this function is being called every time a mouse movement is detected, it slows down the app and hurts workflow.
Is there a way to assign a KeyPressFunction to the button instead, so the shifted focus won't be a problem?
