MATLAB: Removing all highlightning programmatically

Question

Hello,

I am creating/deleting programmatically some simulink functions recursively, and for debug purpose, I hilghlight blocks I'm currently working on with the hilite_system function, for example:

hilite_system(gcbh)

I know I can remove the highlighting of a specific block by doing:

hilite_system(gcbh,'none')

But I don't manage to remove all the highlighting at once.

My question is, is there a simple way to do a global "Remove Highlighting" just like Simulink does (without specifying some blocks), or do I have to make a loop and force all my blocks to none one after another? It would work, but it feels like crushing a fly with a cannon.

I found the function remove_hilite.p but I don't manage to do what I intend with some random arguments.

Thanks,

There is no single function that can do this. You will need to use a collection of find_system and hilite_system to do this. Example below.

% Get highlighted blocks. Idea is to look for all blocks with yellow background (default highlight color). 
% This results in a cell array of paths to all blocks that satisfy this condition.
% Note that if your highlight color is different or more than one color, you would need to run an 
% appropriate or multiple commands to get the list of all blocks highlighted no matter what color.
hilited_blocks =  find_system('my_model','BackgroundColor','yellow')
% Pass block list to hilite_system to switch 'off' color.
hilite_system(hilited_blocks,'off')
