Re: FXScrollWindow

I added VSCROLLING_OFF up the chain but it still does not scroll
when over the treelist, it still works when over the checkboxes.
I can scroll horizontally when over the treelist.

	_checkBox_SW = new FXScrollWindow(splitter_left_VF_0,
HSCROLLING_OFF | LAYOUT_FILL);
	FXHorizontalFrame* HF_SW = new
FXHorizontalFrame(_checkBox_SW, LAYOUT_FILL | FRAME_SUNKEN |
VSCROLLING_OFF);
	_checkBoxes_VF_0 = new FXVerticalFrame(HF_SW,
LAYOUT_FILL_Y | VSCROLLING_OFF, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);	
	_treeList_TL = new FXTreeList(HF_SW, this, ID_TREE_LIST,
LAYOUT_FILL | TREELIST_SINGLESELECT | VSCROLLING_OFF);

FXTreeList itself can also scroll, so it consumes SEL_MOUSEWHEEL
events, and thereby prevents FXScrollWindow from receiving them.

If FXTreeList is forbidden to scroll (e.g. VSCROLLING_OFF or
HSCROLLING_OFF, then it's onMouseWheel returns 0.  In that case,
FXApp tries to dispatch the SEL_MOUSEWHEEL to the parent of
FXTreeList (and its parent, until the events is consumed
somewhere).


Hope this helps,
