The SelectionMorph itself uses the default border width. You can change that by adding for example borderWidth := 4 in the initialization method. the thin border around the selected elements is created by the a 4 times shifted drawing (in drawOn:) (0@0) fourNeighbors do: [:d | form1 displayOn: form2 at: d rule: Form under]. 2015-09-03 22:09 GMT+02:00 christofbuerger via Pharo-users < pharo-users@lists.pharo.org>:

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
