BOOL TrackPopupMenu(
   UINT nFlags,
   int x,
   int y,
   CWnd* pWnd,
   LPCRECT lpRect = 0



Specifies screen-position and mouse-position flags. See TrackPopupMenu for a list of available flags.


Specifies the horizontal position in screen coordinates of the pop-up menu. Depending on the value of the nFlags parameter, the menu can be left-aligned, right-aligned, or centered relative to this position.


Specifies the vertical position in screen coordinates of the top of the menu on the screen.


Identifies the window that owns the pop-up menu. This parameter cannot be NULL, even if the TPM_NONOTIFY flag is specified. This window receives all WM_COMMAND messages from the menu. In Windows versions 3.1 and later, the window does not receive WM_COMMAND messages until TrackPopupMenu returns. In Windows 3.0, the window receives WM_COMMAND messages before TrackPopupMenu returns.



This method returns the result of calling TrackPopupMenu in the Platform SDK.

A floating pop-up menu can appear anywhere on the screen.
