Dear IDL fans,
I have the following issue with widget handling:
I have a main screen to my program, namely screen_100. The top level
base widget for this happens to be "w_bas_main". I have created
another modal screen, screen_200 that has "w_bas_main" to be it's
group leader.
When I first run the program, I simply move the screen_100 to some
arbitrary position on the screen. When I invoked screen_200, I
expected the modal screen_200 to appear directly above screen_100,
possibly overlapping a certain area of screen_100 (as illustrated
below).
Sadly, modal screen_200 always appears at the left top corner of the
screen, no matter where the main screen, screen_100 is positioned.

I have pasted the definitions of both screen_100 and screen_200 below.
Kindly help me fix the aesthetics of my program :).
;---------------------------
; Screen 100
;---------------------------
w_bas_main_100 = Widget_Base( GROUP_LEADER=wGroup, UNAME='w_bas_main'
$
,YOFFSET=5 ,SCR_XSIZE=800 ,SCR_YSIZE=620 $
,NOTIFY_REALIZE='init_screen_100' ,TITLE='TreeVaw � Ver 1.0' $
,SPACE=3 ,XPAD=3 ,YPAD=3 ,MBAR=w_bas_main_MBAR)
;---------------------------
; Screen 200
;---------------------------
wGroup = <widget ID of w_bas_main_100> ; w_bas_main belongs to screen
100
w_bas_main_200 = Widget_Base( GROUP_LEADER=wGroup, $
UNAME='w_bas_main_200' ,XOFFSET=5 ,YOFFSET=5 ,SCR_XSIZE=500 $
,SCR_YSIZE=400 ,TITLE='Image Processing Parameters' ,SPACE=3 $
,XPAD=3 ,YPAD=3 ,/MODAL,TLB_FRAME_ATTR=8, /FLOATING)
;---------------------------
PS: I have tried making the main screen 100 as floating. But the
following code generated by GUI builder keeps me from running the
program.
;---------------------------
; This is the troublesome piece of code
; that prevents me from declaring the
; main screen, screen_100 to be floating,
; as I do not know the group leader for the
; very first screen that I create
;---------------------------
if(N_Elements(wGroup) eq 0)then $
Message,'Group leader must be specified for Modal or Floating'+ $
' top level bases'
Kind regards, Ananth Kini
