Popup (or Context) Menu

[Comadreja]

Hi, I'm working with Visual C++ 6.0 and Directx 8.0 SDK

I'm making a simple GUI with the Control based in Popup Menus.

I make a Menu Resource, then load it, then launch it on Right Mouse Button Click. The problem is that i'm not getting the captions of the menu shown. Instead, the menu appears as if my captions where one blank space each. Still i get all the WM_COMMAND message well on each caption, and even popup submenus appear correctly (Opcion4). Any idea in what I might be doing wrong?

Thx in advance

/**************** RESOURCE.H ********************/
IDR_MENU MENU DISCARDABLE 
BEGIN
    MENUITEM "Opcion1",                     IDM_OCION1,
    MENUITEM "Opcion2",                     IDM_OPCION2, CHECKED
    MENUITEM "Opcion3",                     IDM_OPCION3
    POPUP "Opcion4"
    BEGIN
        MENUITEM "Sub1",                        IDM_OPCION4_SUB1
        MENUITEM "Sub2",                        IDM_OPCION4_SUB2
    END
END

/************* MAINAPP.cpp *******************/
[...]
// INIT INSTANCE
m_hMenuPopup = LoadMenu(hInstance, MAKEINTRESOURCE(IDR_MENU));

[...]
// MESSAGE LOOP
 case WM_RBUTTONDOWN:
            TrackPopupMenuEx(m_hMenuPopup, TPM_LEFTALIGN, 
                           m_cursor.x, m_cursor.y, hWnd, NULL);
[...]

Note: If I append the Captions directly to the Menu, they appear correctly. But I'd like to make the Menus with the resource editor rather that build them line by line in my code

// THIS WORKS
    m_hMenuPopup = CreatePopupMenu();
    AppendMenu(m_hMenuPopup, MF_STRING, 1, "Opcion1");
    AppendMenu(m_hMenuPopup, MF_STRING, 2, "Opcion2");
    AppendMenu(m_hMenuPopup, MF_STRING, 3, "Opcion3");

When loading a popup menu from a resource, you need to define a top-level, 'dummy' popup menu under which you create the items you want to display. The top level item will never actually show when displaying a popup menu.

Thanks a lot!!!! That worked!

I made the 'dummy' popup menu, then obtained a handle to the submenu and it loaded OK.
I insert the code working in case it helps someone else

/**************** RESOURCE.H ********************/
IDR_MENU MENU DISCARDABLE 
BEGIN
    POPUP "Menu Popup"
    BEGIN
        MENUITEM "Opcion1",                     IDMP_1
        MENUITEM "Opcion2",                     IDMP_2
        MENUITEM "Opcion3",                     IDMP_2
    END
END

/************* MAINAPP.cpp *******************/
[...]
// INIT INSTANCE
m_hMenuPopup = LoadMenu(hInstance, MAKEINTRESOURCE(IDR_MENU));

[...]
// MESSAGE LOOP
 case WM_RBUTTONDOWN:
            TrackPopupMenuEx(GetSubMenu(m_hMenuPopup,0), TPM_LEFTALIGN,
                           m_cursor.x, m_cursor.y, hWnd, NULL);
[...]

What I still don't understand is why the captions didn't appear without the 'dummy menu'. It might be because it is a popup menu?? And if so, why appending the captions directly in the code worked well?


Nevermind, if it works it works!

Now I'm getting into a new question: is there any function to easily change the captions of the menu without affecting its IDs? I'm thinking of multi-language GUI, and a way to load all the new captions from a file when changing the language. I'm investigating the InsertMenuItem function but it don't find a way to just replace the caption without changing anything else. Any idea on this?
