How do I create an On/Off button in Simulink with a clickfcn from an annotation

Hi, I created on Simulink a clickfcn from an annotation to comment out a block. Now I want to uncomment the block with a second click on the annotation clickfcn. Also the background color from the annotation should change to: green = comment out and red = uncomment.

You can use an annotation to comment and uncomment a block by enterting the code below as the 'ClickFcn' for the annotation.

if(strcmp(get_param(path_to_block,'Commented'),'on'))
    set_param(path_to_block,'Commented','off');
else
    set_param(path_to_block,'Commented','on');
end

Unfortunately, annotation properties can not be accessed programatically and hence, you will not be able to change the color of the annotation based on whether the block is commented or not.
