As I've almost finished term for my 6 week Christmas holiday (life's so
hard) then I would have been happy to give this a go. There is one major
problem which will stop it from working however. You can't create table
widgets that don't have scroll bars and so you can't create a single
standalone cell, which could look like a CW_Field. Try this code to see what
I mean:
base = Widget_Base()
table = Widget_Table(base, XSIZE=1, YSIZE=1, VALUE=[0], ROW_LABELS=[' '],
COLUMN_LABELS=[' '], SCROLL=0)
Widget_Control, base, /REALIZE
See what I mean - it just looks messy. Well it does on windows, at least,
I'm not sure about UNIX. So I', afraid this idea's a bit of a non starter (I
think).
Cheers,
