Wow, you guys are getting a bit philosophical here. This is my first
posting and OK you definitely have my respect, but could you possibly
lower yourself to helping with questions like 'Why I don't get multiple
element output from my list widget?' please?
Here is my widget_definition:
Widget_list(tlb,sensitive=1,/multiple,ysize=26,event_pro='an ypro')
So I get my array of filenames into my list widget and then try to
select four files by left click + shift left click below (or just
dragging the cursor) so it highlights the desired four file names and
the event.index only gives the index of the last filename.
Is there something obvious I'm doing/not doing or some secret IDL kung
fu I could perform to get it to work?
Thanks very much,
Stu.

Dear Stuart,
we are using a compound widget to select from a list.
You can do a selection by typing something in the text field.
Example:
PRO test_event,ev
WIDGET_CONTROL,ev.id,get_uval=cmd
WIDGET_CONTROL,ev.top,get_uvalue=b
CASE cmd OF
'done':BEGIN
WIDGET_CONTROL,b,get_value=v
IF v.list_selected[0] NE -1 THEN PRINT,v.list[v.list_selected]
WIDGET_CONTROL,ev.top,/dest
END
'FF':BEGIN
WIDGET_CONTROL,ev.id,get_value=v
IF v.button_pressed EQ 1 THEN BEGIN
replace_tag,v,'list_selected','list_selected',INDGEN(2)
WIDGET_CONTROL,ev.id,set_value=v
ENDIF
END
ELSE:
ENDCASE
END
PRO test
a=WIDGET_BASE(row=2,/frame)
value={label:'[0,1]',list:STRTRIM(SINDGEN(40),2),text:'',but ton:'PRESELECTION',$
list_selected:-1,button_pressed:0,description:'TEST'}
b=cw_list(a,value=value,uvalue='FF',frame=2, XOFFSET=9,$
YOFFSET=15 ,SCR_XSIZE=140 ,SCR_YSIZE=200,$
/text_all_events, text_xsize=19,/text_editable, $
/list_multiple,list_ysize=10,list_xsize=20,$
label_xsize=100,$
button_ysize=20 )
d=WIDGET_BUTTON(a,val='done',uval='done')
WIDGET_CONTROL,/realize,a,set_uvalue=b
XMANAGER,'test',a
END
