DW expression without explicitely naming the control

Question

Hello, all
I have a theoretical question regarding DW.
Some of my DW's are denced charts with numerous controls. These controls do not have enough space to show all the needed data, so they have tooltips. Each control has the following expression (or something similar) in the tooltip : describe("controlname.text")
My question is: is it possible not to name the control explicitely in the expression, but use some other relative expression, which returns the current control (the tooltip text is always dependent on the data in it's own control).
I hope my quesiton was not too confusing. I know how to make it work in the code, I just go over the controls and set the tooltip accordingly on each one. But is it possible to set the same exact extression in the painter itself?
Thank you
Arcady

Hi,
You can try this :
Create a custom event ue_mouseover dor the DatWindow control mapped to pbm_dwnmousemove.
in this event add this code :
string  ls_obj,  ls_value, ls_datatype
ls_obj = string (dwo.name)
ls_value =  describe (ls_obj + ".Text")
if ls_value = "!"Then
if row <=0 then
  return
else
  ls_datatype = describe (ls_obj + ".Coltype")
  choose case lower (left (ls_datatype, 3))
  case "cha"
   ls_value = GetItemString (row, ls_obj)
  case "ulo", "lon", "dec", "int"
   ls_value = string (GetItemNumber(row,ls_obj))
  case else
   ls_value = "!!!???"
  end choose
end if
end if
modify (ls_obj + ".Tooltip.tip='" + ls_value + "'")
It works for a 'normal' datawindow but did not test it with crosstabs, graph datawindows.
HTH.
