Hi all,
i am using App Designer to build an app including a radio button group. I want to be able to change the selection by mouse click (works fine) but also by using the arrow keys. When using the mouse to change from left to right radio button it looks like this:

I also have created a KeyPressFcn that works mainly fine. But when i change the button groups selection by code with the KeyPressFcn, only the black dot moves, but not the blue highlight circle:

Hereby it doesn't matter if i use
app.rightbutton.Value = true;
or
app.buttongroup.SelectedObject = app.rightbutton
Any idea how to get the blue circle to move as well when using code to change the selction or how to disable it completely?
Regards,
Matthias

I'm having trouble reproducing this behavior. I'm only able to get UIFigureKeyPress to trigger when I select outside of the radio button group which removes the blue circle altogether. Would you mind attaching your app or a watered down version of it?
