Change the transparency of the window

[Natter]

I need to change the transparency of the window.I try this way, but nothing changes. How can this problem be solved ?

Code: Select all  Expand view  RUN

#include "fivewin.ch"

function Main
private oDlg

  DEFINE DIALOG oDlg FROM 0,0 TO 300,300  PIXEL ;
           STYLE nOR(WS_POPUP, WS_THICKFRAME) ;
           COLOR CLR_BLACK, RGB(152, 251, 152) RESIZABLE

    ACTIVATE DIALOG oDlg  ON INIT   oDlg:nOpacity:=100 NOWAIT
    oDlg:bLDblClick:={||Chg_Tsp()}
return NIL

procedure Chg_Tsp
  oDlg:nOpacity:=iif(valtype(oDlg:nOpacity)="N", NIL, 100)
  oDlg:Refresh()
return

     TRANSPARENT

   oDlg:bLDblClick:={ || Chg_Tsp() } // Double Click()

   // error:
   // ACTIVATE DIALOG oDlg  ON INIT   oFrg:nOpacity:=100 NOWAIT

   ACTIVATE DIALOG oDlg ON INIT( oDlg:nOpacity := 100 ) // NOWAIT test

RETURN NIL

FUNCTION Chg_Tsp()

   ? "yes?"

  // oDlg:nOpacity:=iif(valtype(oDlg:nOpacity)="N", NIL, 100)

  oDlg:nOpacity := 180

  // oDlg:Update()
  // oDlg:Refresh()

RETURN NIL

//FIN / END
