i'm trying to capture mouse click events before children. but I'm having some difficulty. please correct me if I'm wrong:

* to do this, i need to return false for all mouse events (or at least for MOUSE_ENTERED) in direct children, and direct children of children. otherwise that child (direct or indirect) will have mouse focus and mouse events will be routed to it
* -although too verbose- this works, but in this case child widget's custom cursor is not rendered. because getWidgetUnderMouse never points to that child widget.

There is no way to intercept mouse routing like that. Why do you need that?

for something like "click to scroll" list. but i guess there can be many other uses.

Can't you just have the widgets report drag events to the parent - similar to how TextArea and ScrollPane do it?

yes, that's also possible I suppose. but it's not nice a widget knows about its ListBox like parent.

maybe putting an invisible "glass pane" covering all the widget area is the way to go, what do you think?
