Menu at runtime (dynamic menu)
-
Hi, I have a class (CVidCap) that I developed to grab frames from a Webcam and I want to make this a "dialog independent" class. When this class is created it populate a CMenu (MFC) object with all Webcam available in the system and i design a function that append this CMenu object in an application MenuBar. The problem is that when the CMenu object is attached, it is alweys GRAYED, and I can't handle any mouse button press in my class. I'm trying to handle the application events in my independent class without insert any code in the application MESSAGE_MAP. I was clearly?
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd) //{{AFX_MSG_MAP(CMainFrame) ON_COMMAND(ID_TESTE_B, OnTesteB) //}}AFX_MSG_MAP END_MESSAGE_MAP()I try to add a message map in my class but didn't work. :( If anybody could help, I'll appreciate! Thanks, and sory my english! :) Marcos Vinícius Engenheiro Eletricista -

Yes, I try this, but the menu that I append is still grayed!!!
CMenu *Menu = Wnd->GetMenu(); hr = Menu->InsertMenu(Position, MF_BYPOSITION | MF_STRING | MF_POPUP | MF_ENABLED, (UINT)DevicesMenu->m_hMenu, TEXT("Devices")); Menu->Detach(); Wnd->DrawMenuBar();The only way that they work properly is to add in the AppClass file MESSAGE_MAP the code:// file "MyApp.cpp" BEGIN_MESSAGE_MAP(CTe13App, CWinApp) //{{AFX_MSG_MAP(CTe13App) ON_COMMAND(ID_APP_ABOUT, OnAppAbout) ON_COMMAND(ID_PAUSE, OnPause) //}}AFX_MSG_MAP // My message map ON_COMMAND_RANGE(ID_MENU_DIALOG0, ID_MENU_DIALOG9, OnDialog) END_MESSAGE_MAP()but I don't want to do this. I need to be App independent; to be an independent class!! Is there a way that adding a message map in my class, the app message map understand? Like this: // file "MyClass.cpp" BEGIN_MESSAGE_MAP(CVidCap, CWnd) ON_COMMAND_RANGE(ID_MENU_DIALOG0, ID_MENU_DIALOG9, OnDialog) END_MESSAGE_MAP() Thanks Marcos Vinícius Engenheiro Eletricista -

For instance, you can catch your menu item handler in your View. You can have it in your CDialog , CView or CFrameWnd. Just make sure your menu ID constant to be included in the source.

It means that I always have to put some extra-code in my CDialog, CView or CFrameWnd? I can't just make an object that handle the menu messages without put any extra-code?
// MyApp.h ... private: CMyClass *MyObject; ... // MyApp.cpp ... BOOL MyApp::InitInstance() { // All I need? - All I want! MyObject = new CMyClass(); ... }Thanks Anthony Marcos Vinícius -
