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
