Ckeditor On Font-size Change Event

Is there any way to capture an event when user has changed font-size? I'm looking for something similar to this: CKEDITOR.editor.getCommand('xxx').on('xxx', function(){ });

Solution 1:

You need to use:

CKEDITOR.instances.your_instance_name.on( 'change', function() {
    //  Code goes here
} );

Replace your_instance_name with your instance name.
