Hello.

 How can I disable the menu that appear on mouse right click when I’m in CExtControlBar. I don’t need this menu and I want him do disapear.

Thank  

We guess you have nothing against the context menu with a list of all toolbars and resizable control bars but you don’t want this menu to appear over the window inserted into the resizable control bar. In this case, just add a message handler for the WM_CONTEXTMENU Windows message to the window inside the resizable control bar. This message handler should do nothing or show your own context menu

That’s works fine if the control bar is docked. But if the control bar is floating and I right click on the title of the control bar, the menu still appear although I have a handler for WM_CONTEXTMENU (which works fine in the rest of the cases). Could you tell me how I get rid of this menu (is good but I do not need it).

Of course you can avoid displaying of built-in Prof-UIS menus. Your frame window receives the CExtControlBar::g_nMsgConstructPopupMenu registered windows message which allows you to construct, modify or cancel any built-in menu. Add the following code to your main frame class and its message map:

afx_msg LRESULT OnConstructPopupMenuCB(
   WPARAM wParam, LPARAM lParam );
ON_REGISTERED_MESSAGE(
    CExtControlBar::g_nMsgConstructPopupMenu,
    OnConstructPopupMenuCB
)
 
LRESULT CMainFrame::OnConstructPopupMenuCB(
    WPARAM wParam, LPARAM lParam )
    {
       wParam;
      lParam;
      return (!0);
    }

This implementation of the CExtControlBar::g_nMsgConstructPopupMenu message handler cancels any built-in menu. For instance, the following implementation cancels context menus over any dockable control bars (menu bar, toolbar, or resizable control bar) and status bar:

LRESULT CMainFrame::OnConstructPopupMenuCB(
   WPARAM wParam, LPARAM lParam )
   {
      ASSERT_VALID( this );
      lParam;
      CExtControlBar::POPUP_MENU_EVENT_DATA * p_pmed =
         CExtControlBar::POPUP_MENU_EVENT_DATA::
            FromWParam( wParam );
      ASSERT( p_pmed != NULL );
      ASSERT_VALID( p_pmed->m_pPopupMenuWnd );
      ASSERT_VALID( p_pmed->m_pWndEventSrc );
      ASSERT(
         p_pmed->m_pWndEventSrc->
            GetSafeHwnd() != NULL
         );
      ASSERT(
         ::IsWindow(
            p_pmed->m_pWndEventSrc->
            GetSafeHwnd())
         );
        if( p_pmed->m_bPostNotification )
            return 0;
        if(    p_pmed->m_nHelperNotificationType ==
                 CExtControlBar::POPUP_MENU_EVENT_DATA::
                    __PMED_CONTROLBAR_CTX
            || p_pmed->m_nHelperNotificationType ==
                 CExtControlBar::POPUP_MENU_EVENT_DATA::
                    __PMED_CONTROLBAR_NC_CTX
            || p_pmed->m_nHelperNotificationType ==
                 CExtControlBar::POPUP_MENU_EVENT_DATA::
                    __PMED_STATUSBAR_CTX
            )
            return (!0);
        return 0;
   }

By playing with __PMED_... constants, you can cancel any context menu. The declarations and descriptions of all these constants you can find in the ExtControlBar.cpp file

Let’s suppose that from CMainFrame we construct more CExtControlBar derived class, each of them displaying individual data. Each of this CExtControlBar derived  should have  an individual context menu that is build at run time. But I have one problem: I am not able to intercept the message g_nMsgConstructPopupMenu in  CExtControlBar derived class. I could use OnContextMenu, but this method is not called when the user right click on the title bar of the CExtControlBar. How can I intercept  g_nMsgConstructPopupMenu in the CExtControlBar derived class?

If you want to customize any context menu over control bar areas displayed by Prof-UIS framework, then you should handle the CExtControlBar::g_nMsgConstructPopupMenu registered windows message as it is done in the ProfStudio application (CMainFrame::OnConstructPopupMenuCB() method):

LRESULT CMainFrame::OnConstructPopupMenuCB(
    WPARAM wParam, LPARAM lParam
    )
{
    ASSERT_VALID( this );
    lParam;
CExtControlBar::POPUP_MENU_EVENT_DATA * p_pmed =
        CExtControlBar::
            POPUP_MENU_EVENT_DATA::
                FromWParam( wParam );
    ASSERT( p_pmed != NULL );
    ASSERT_VALID( p_pmed->m_pPopupMenuWnd );
    ASSERT_VALID( p_pmed->m_pWndEventSrc );
    ASSERT( p_pmed->m_pWndEventSrc->GetSafeHwnd() != NULL );
    ASSERT( ::IsWindow(p_pmed->m_pWndEventSrc->GetSafeHwnd()) );

    if( p_pmed->m_bPostNotification )
    {
        // if you want to construct popup menu completely,
        // then do it and return 0 here
    }
    else
    {
        // modify default menu
        return 0;
    }
}

This message handler allows you to modify or completely reconstruct any built-in Prof-UIS menu. The p_pmed->m_nHelperNotificationType value can be one of the following list:

• __PMED_DOCKBAR_CTX - dockbar context menu
• __PMED_CONTROLBAR_CTX - any control bar context menu (client area)
• __PMED_CONTROLBAR_NC_CTX - any control bar context menu (non-client area)
• __PMED_STATUSBAR_CTX - status bar context menu
• __PMED_AUTOHIDESLIDER_CTX - autohide slider window context menu
• __PMED_MINIFRAME_NC_CTX - miniframe context menu (non-client area)
• __PMED_MDICLIAREA_CTX - MDI client area context menu
• __PMED_MDITABS_CTX - MDI-tabs window
• __PMED_AUTOHIDETABS_CTX - autohide-tabs window
• __PMED_DYNCBCTABS_CTX - dynamic control bar container tabs window
• __PMED_CONTROLBAR_NCBTNMENU_TOP - control bar nc-area-menu-button - top level
• __PMED_CONTROLBAR_NCBTNMENU_BARS - control bar nc-area-menu-button - control bars list
• __PMED_CTXEXPBTN_TOP - content expand button - top level
• __PMED_CTXEXPBTN_APPEND - content expand button - append to buttons list
• __PMED_CTXEXPBTN_BARS - content expand button - control bars list

If you need to add support for context menus over a window inside a resizable control bar, then you should handle the WM_CONTEXTMENU windows message in the window inserted into resizable bar and this will work. The g_nMsgConstructPopupMenu message is sent to window which handle is specified when invoking CExtPopupMenuWnd::CreatePopupMenu() or CExtPopupMenuWnd::LoadMenu() methods
