How to change the mask icon dynamically based on the input?

Hi,

I am going to demonstrate an LED on my Simulink model. I would like to turn the LED on/off based on the input. I could not find any way, therefor I thought it may be a good idea to change an image or text of the mask's icon. I tried to write a simple 'if' in the 'Icon drawing commands' but I was not successful. Does anybody have any idea? Thank you in advance.

Best Retards,

Saeed

I have solved my problem by using another Matlab function block and set_param.
