Thank you very much for your responses:

Well, maybe both of you are right, I don't really know. DRAW288_Id does
work with all WSETs that occur in the code. But it contains the 'IDL window
number' (says the manual):
PRO MainProg, GROUP=Group
[...]
DRAW288 = WIDGET_DRAW( BASE290, $
BUTTON_EVENTS=1, $
MOTION_EVENTS=1, $
RETAIN=2, $
UVALUE='MainViewDraw', $
XSIZE=741, $
YSIZE=574)
[...]
WIDGET_CONTROL, DRAW288, GET_VALUE=DRAW288_Id
[...]
END
This window number (more or less) obviously is something different
from a 'window id', which in this case is stored in DRAW288. And
CW_DEFROI only accepts window ids, not window numbers. So, for
the time being, I added DRAW288 to my DRAW_Comm block, and it now
sort of works. Thanks a lot.
Still though, the STRING persists, but it seems not to do any harm
(here and at this point...). Just to close this thread, here's the
code snippet:
[...]
'DISPLAY.Display Mode.ROI': BEGIN
MESSAGE, 'Event for DISPLAY.Display Mode.ROI', /INFORMATIONAL
JUNK = WIDGET_INFO(DRAW288_Id, /NAME)
PRINT, 'HELP, JUNK :' & HELP, JUNK
WSET, DRAW288_Id
WIDGET_CONTROL, DRAW288_Id, GET_VALUE=win
PRINT, 'HELP, WIN :' & HELP, win
PRINT, 'HELP, DRAW288_Id :' & HELP, DRAW288_Id
PRINT, 'HELP, DRAW288 :' & HELP, DRAW288
ROI=CW_DEFROI(DRAW288,/RESTORE)
PRINT, 'HELP, ROI :' & HELP, ROI
END
[...]
now produces:
% PDMENU298_EVENT: Event for DISPLAY.Display Mode.ROI
HELP, JUNK :
JUNK STRING = 'BUTTON'
HELP, WIN :
WIN STRING = 'Display Mode'
HELP, DRAW288_Id :
DRAW288_ID (DRAW_COMM)
LONG = 32
HELP, DRAW288 :
DRAW288 (DRAW_COMM)
LONG = 52
% Compiled module: CW_DEFROI.
% Compiled module: CW_BGROUP.
HELP, ROI :
ROI LONG = Array(57730)
I'm afraid, I'll have to leave that to those with further insight.
Ask me if I can be of any help, if there's still interest in this.
Now, after another lenghty posting, thank you all again, I will now
go on and try to produce some other image from this ROI array...
Best regards,
Peter.
