MATLAB: How to change an image (icon) on button into another one image (icon) by clicking on this button in Matlab’s App Designer

app designerMATLAB

Hi everyone,
This is necessary for the audio player for the play/pause button. For example, while the "play" button is pressed, an image (icon) appears on the pause button.
I don't understand how this can be added for a button. I can't find any decision to solve it. I need your help. Thank you for responce!

You will need to do this in the callback of your button.
Assuming that when you create the button, you had set the text to Play and set the Icon file to play icon image.
function ButtonDownFcn(app,event)
    switch app.Button.Text
        case 'Play'
            % do something to play 
            % change the text and icon

            app.Button.Text = 'Pause';
            app.Button.Icon = 'Pause.png'; % path to image file

        case 'Pause'
            % do something to pause
            % change the text and icon
            app.Button.Text = 'Play';
            app.Button.Icon = 'Play.png'; % path to image file
    end
end
