Micheus ... Selection Groups scroll vs Geometry Graph Scroll

[micheus]

It would be better to add the thumb-region handling that is supported by geometry graph.

yeah, you are right. And yes, the second options seems to be better - no time to check this now.

About to use keys I'm not sure it would be productive to implement it. This king of window requires the mouse be over in order to get the focus and then try to capture the keyboard event. By now I think it's easier to use it to scroll the items.

Add support to key handling was something I thought about (sometime after release it) in order allow us to make a multiple selection. Something that I didn't spend time thinking about until know if this kind of windows will be replaced by some wxWidgets control.
