WinApi, ATL creating context menu function handler - winapi

Question

The code below creates a window, implements a CListViewCtrl and tries to make a context menu with 3 options: new, edit & delete.
class CGuiView : public CWindowImpl<CGuiView, CListViewCtrl>
{
HMENU hPopupMenu;
MENUINFO m_ContextMenuInfo;
public:
DECLARE_WND_CLASS(NULL)
BOOL PreTranslateMessage(MSG* pMsg)
{
pMsg;
return FALSE;
}
BEGIN_MSG_MAP(CGuiView)
MESSAGE_HANDLER(WM_PAINT, OnPaint)
// MESSAGE_HANDLER(WM_LBUTTONUP,)
MSG_WM_CONTEXTMENU(OnContextMenu)
COMMAND_ID_HANDLER(ID_CTXMENU_NEW, OnNewTask)
END_MSG_MAP()
LRESULT OnPaint(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
{
CPaintDC dc(m_hWnd);
//TODO: Add your drawing code here
return 0;
}
void OnContextMenu ( HWND hwndCtrl, CPoint ptClick )
{
hPopupMenu = CreatePopupMenu();
InsertMenu(hPopupMenu, 0, MF_BYCOMMAND | MF_STRING, ID_CTXMENU_DELETE, TEXT("Delete"));
InsertMenu(hPopupMenu, ID_CTXMENU_DELETE, MF_BYCOMMAND | MF_STRING, ID_CTXMENU_EDIT, TEXT("Edit"));
InsertMenu(hPopupMenu, ID_CTXMENU_EDIT, MF_BYCOMMAND | MF_STRING | MF_ENABLED, ID_CTXMENU_NEW , TEXT("New"));
TrackPopupMenu(hPopupMenu, TPM_TOPALIGN | TPM_LEFTALIGN, ptClick.x, ptClick.y, 0,GetParent(), NULL);
}
LRESULT OnNewTask(WORD /*wNotifyCode*/, WORD /*wID*/, HWND /*hWndCtl*/, BOOL& /*bHandled*/)
{
CAboutDlg dlg;
dlg.DoModal();
return 0;
}
};
The problem is that the code above does not enter OnNewTask when I click on the New menu item that I create in the OnContextMenu function. What I am doing wrong?

Answer 1

You are providing GetParent() as an argument to the TrackPopupMenu API function. So WM_COMMAND is sent to the list view parent, not list view itself.
Have it sent to the list view, or forward commands from parent to list view. You can also use Spy++ tool to check the messages in the debugged process to see what exactly is sent and where.
