Now I tried with

Code: Select all  Expand view  RUN

 for n := 1 to 10
      @ nRow, nCol BTNBMP aBtn[ n ]  RESOURCE OMB_LIBERO  ;
         SIZE 84,64 PIXEL OF oDlg FLAT TOP COLOR CLR_WHITE,CLR_GREEN NOBORDER

WITH OBJECT aBtn[ n ]
         :Cargo      := n
         :bRClicked    := { | nRow, nCol, oBtn | EseguiButton(nrow, ncol, n, oBtn) }
 END
 next n

FUNCTION EseguiButton( nrow, ncol, n, oControl )
RETURN { |n| Menu_popup( nrow, ncol, n, oControl )  }

FUNCTION Menu_Popup( nrow, ncol, n, oControl )
Local oMenuPop
  MENU oMenuPop POPUP 2015
   MENUITEM "Apri "
    MENUITEM "Apri "

 ACTIVATE POPUP oMenuPop OF oControl AT nrow, ncol
 oControl:Refresh()
 RETURN NIL

but not make error and not show the menu popup

Please, search for "detached locals technicque", in forum
It is very possible that this is the problem

???????

First please implement a small fix in btnbmp.prg.
Locate the following lines in the method ShowPopUp()

Code: Select all  Expand view  RUN

     if GetClassName( GetParent( Self:hWnd ) ) != "TBAR"
         oWnd = oWndFromhWnd( GetParent( Self:hWnd ) )
      endif
 

Comment out all the 3 lines above.

Next, please try this program:

Code: Select all  Expand view  RUN

#include "fivewin.ch"

function Main()

   local oDlg, oFont, aBtn[ 5 ]
   local aBmp := { "attach.bmp", "browse.bmp", "calc.bmp", "cascade.bmp", "copy.bmp" }
   local n, nRow, nCol

   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-14
   DEFINE DIALOG oDlg SIZE 700,400 PIXEL TRUEPIXEL FONT oFont

   nRow  :=  40
   nCol  :=  40

   for n := 1 to 5
      @ nRow, nCol BTNBMP aBtn[ n ] FILE "c:\fwh\bitmaps\32x32\" + aBmp[ n ] ;
         PROMPT NtoCMonth( n ) ;
         SIZE 100,100 PIXEL OF oDlg TOP FLAT COLOR CLR_WHITE,CLR_GREEN NOBORDER ACTION ::ShowPopup()

      aBtn[ n ]:Cargo   := n
      aBtn[ n ]:oPopUp  := { |oBtn| BtnPopMenu( oBtn ) }

      nCol  += 120
   next

   ACTIVATE DIALOG oDlg CENTERED
   RELEASE FONT oFont

return nil

function BtnPopMenu( oBtn )

   local oPop
   local n

   MENU oPop POPUP 2007
   for n := oBtn:Cargo + 1 to 12
      MENUITEM NToCMonth( n )
   next
   ENDMENU

return oPop

Thank
can we erase or not show the part where is the black Arrow ?

[nageswaragunupudi]

Please make this modification

Code: Select all  Expand view  RUN

  for n := 1 to 5
      @ nRow, nCol BTNBMP aBtn[ n ] FILE "c:\fwh\bitmaps\32x32\" + aBmp[ n ] ;
         PROMPT NtoCMonth( n ) ;
         SIZE 100,100 PIXEL OF oDlg TOP FLAT COLOR CLR_WHITE,CLR_GREEN NOBORDER ; // ACTION ::ShowPopup()
         ACTION ( ::oPopup := { |oBtn| BtnPopMenu( oBtn ) }, ;
                  ::ShowPopUp(), ;
                  ::oPopup := nil )

      aBtn[ n ]:Cargo   := n
//      aBtn[ n ]:oPopUp  := { |oBtn| BtnPopMenu( oBtn ) }

      nCol  += 120
   next

then when It show the menu it create the part with black arrow
on oldest release of my prg it not is showed
when I click on btnbmp it open a popupmenu near the btnbmp and I not see the part with black arrow
for my advice the black arrow can be usefull ony on a tbar control

for now I resolved with rem on METHOD PaintPopupSection()
on future we can apologize a logic variable to show or not the popupsection when the btnbmp is not on tbar





We suggest

if ::oPopup != nil .and. GetClassName( GetParent( Self:hWnd ) ) = "TBAR"
