Re: FXTreeList scrolling

I wound up making a TreeList_jhs1 class derived from FXTreeList
class which only contains:


FXMAPFUNC(SEL_MOUSEWHEEL,0,TreeList_jhs1::onCmdNotUsed)

/****************************************************************
***************/
long TreeList_jhs1::onCmdNotUsed(FXObject*, FXSelector, void*)
{
	return 0;
}
/****************************************************************
************/

If it is hidden, it will not receive events.  So then events are
passed to the widget underneath, (recursively) until they reach a
place where they're handled.

In an FXScrollWindow or FXScrollArea, the mouse wheel or
right-mouse scroll is handled.  But if it has child windows (in
the case of FXScrollWindow), or is subclassed (FXScrollArea),
those events may be getting handled, and may not reach, or may
only conditionally reach the scrolling windows...
