|Kelly Dean:
| I was wondering if anyone has a Widget version of BOX_CURSOR. BOX_CURSOR
| uses CURSOR, which wipes out the image in WIDGET_DRAW. Before I start
| working on a CW_BOXCUR, I just thought I check to see if anyone has done it
| already.

I just tried BOX_CURSOR on a draw widget and it seems to work OK (IDL 3.6
on a DEC Alpha). You have to do a
c = CONVERT_COORD(x, y, /DEVICE, /TO_DATA)
if you want the x, y, returned by BOX_CURSOR to be in data coord.
I also use CURSOR in a widget-driven program and it seems to work fine,
even though the IDL manual says one shouldn't use CURSOR for draw widgets.
I would try BOX_CURSOR before working on CW_BOX_CURSOR...
