Zoom breaks UIFigureWindowKeyPress in App Designer

8 views (last 30 days)
Using zoom icon in the UIAxis or the zoom() function in the startup function in App Designer seems to be stopping me from also being able to use keyboard callback.
function startupFcn(app)
zoom(app.UIAxes,'on')
end
The callback function below no longer works as desired (printing out each key to the command window).
function UIFigureWindowKeyPress(app, event)
key = event.Key;
disp(key)
end
This seems to be a similar problem to this question. Probably the UIFigure is no longer highlighted. I attached a basic app which shows this problem. Does anyone know how to fix or get around this?

Hi Zel,
When the zoom mode is enabled(using zoom icon or by zoom function), the control stays with the function.
The UIFigureWindowKeyPress event is not triggered with zoom mode enabled because MATLAB supports only 1 function at a time. Once, the zoom mode is disabled, you can see the callback function triggered on keyPress.
If possible, disable the zoom mode from the toolbar and try to trigger the callback again with key press.
As a workaround, you can see how to trigger two or more callbacks concurrently here -

Thanks Ayush! When zoom is disabled from the toolbar, the keys work again as you were saying.
I'll make do without one or the other in my application for now. Cheers
