how to resize icons when resizing objects?

[Tiemo Hollmann TB]

Hello,

I have a stack, which the user may resize and all objects are resized and
positioned dynamically. This works fine. Up to now, I kept the size of the
buttons with assigned icons locked, because I didn't find an approach, how
to resize the assigned icons dynamically? Or don't you do that at all in a
dynamic layout and am I looking for a no go?

Thanks for any hints
