I have a BGroupView with one column, where some views are attached one per row. For a number of reasons, i'm going to change the old selection/focus mechanism previously handled by the childs, so i'm redefining MouseDown/MouseMoved etc. in the BGroupView based (father) class. I was expecting it to detect the mouse as the child class continue to do, but for some reason it isn't happening. Is there something i'm not considering? There's not mention of it in the HaikuBook. It looks strange as the child continue to receive the hook as well.
