Where do selected morphs get their emphasizing frame from

Hello, tried honestly the whole day to figure out how morphs in world get their thicker frame from, when they are selected by a SelectionMorph. I wanted to copy/inherit that behaviour and make the frame for such selected items thicker than it is done by standard. Can anyone please give me a hint?! Thank you very much and Best Regards Christof -- View this message in context: http://forum.world.st/Where-do-selected-morphs-get-their-emphasizing-frame-f...
