Change backround colour of pushbutton to black in GUI

Hi!

I have created a GUI with a piano in matlab. My problem is I want the colour of the pushbuttons at top to be black to make it look more like a Piano, but I'm only able to change the frame colour not the backround colour.

What is the "frame color"? You can set the 'backgorundcolor' of buttons. And when I open your FIG file, the buttons are black.

Are you running this on a Mac, where the button colors are controlled by the operating system?

Yes I'm using a Macbook air! When I open the figure only the frame of the button is black Will try to open my m.file on a W7

Instead of setting the BackgroundColor property, you can use the CData property to superimpose an image onto your button. (This at least worked on Macs several years ago, i haven't tried it recently) If you can draw the button you want, e.g. in photoshop, you can then import it to use on your button.

As a test, try setting the CData property to zeros(m,n,3) where m and n are the width and height of your button in pixels.

What if you only want the colour of a pushbutton to change temporarily when you click it. Then go back to normal colour once you click another button?
