How can I change color of Push Button in Simulink GUI or add a picture?

I have a push button in Simulink GUI, but I can't change its color. When I try to set the background or foreground colors from the properties menu, it doesn't display on the button - it still stays white.

Is there a way to do it programmatically? I tried using the MATLAB GUI push button options, but that approach doesn't work with Simulink.

Or is there a way to add a picture in the button instead of only text?

Hi Diana,

Yes, You can update the background color by using the set function which is used to set all the graphics object properties.

You can set the background color to the push button in this manner,

set(Objectname,'BackgroundColor',[0,0,0]);

You can also set the background image to the push button using set function as follows,

set(Objectname, 'CData', bg_image);

Hope this Helps!

I tried doing both and got the block handle through getSimulinkBlockHandle. But, it still doesn't work. Using

set(handle,'BackgroundColor',[0,1,0])

Gives the following error:

Invalid setting in PushButtonBlock block 'Push Button1' for parameter 'BackgroundColor'

I went ahead and set the color array to a color name and it went through but the color of the button didn't change. However, the parameter itself says that it did.

I also tried using the CData and Simulink returned an error saying:

PushButtonBlock block does not have a parameter named 'CData'

Any other ideas?

Thank you.
