Antonio,

Do you tested try scroll window clicking vertical scroll bar?

When I try scroll window, scroll button bar too.

Eroni,

> When I try scroll window, scroll button bar too.

Yes, but thats a normal behavior as the button bar is a child of the main window

You may use a MDI main window where the buttonbar is and then implement the scroll window on a MDICHILD window

Here you have you sample modified:
Code: Select all  Expand view
#include "FiveWin.ch"

#define D_WIDTH 4
#define D_HEIGHT 13

static oWndMain

function Main()

   local oBar

   DEFINE WINDOW oWndMain TITLE "MDI sample" ;
      MENU BuildMenu() MDI

   DEFINE BUTTONBAR oBar 3D BUTTONSIZE 48, 48 OF oWndMain // here button bar
   
   ACTIVATE WINDOW oWndMain MAXIMIZED
   
return nil   

FUNCTION Child()

LOCAL oWnd,oScrWnd
define window oWnd from 0, 0 TO 25, 70 ;
title "Scroll Window" ;
vscroll hscroll MDICHILD OF oWndMain

TScrWnd():New( oWnd, 1, 40, 1, 70 )

RETURN( NIL )

function BuildMenu()
LOCAL oMenu

MENU oMenu
MENUITEM "&Child Window"
MENU
MENUITEM "&Open" ACTION Child()
MENUITEM "&Close"
MENUITEM "&Save"
MENUITEM "&End"
ENDMENU
ENDMENU

return oMenu
