TrackPopupMenu(IntPtr, UInt32, Int32, Int32, Int32, IntPtr, IntPtr)
The TrackPopupMenu function displays a shortcut menu at the specified location and tracks the selection of items on the menu. The shortcut menu can appear anywhere on the screen.
Declaration
public static int TrackPopupMenu(IntPtr hMenu, uint uFlags, int x, int y, int nReserved, IntPtr hWnd, IntPtr prcRect)Parameters
| Type | Name | Description |
|---|---|---|
| System.IntPtr | hMenu | Handle to the shortcut menu to be displayed. The handle can be obtained by calling CreatePopupMenu to create a new shortcut menu, or by calling GetSubMenu to retrieve a handle to a submenu associated with an existing menu item. |
| System.UInt32 | uFlags | Use zero of more of these flags to specify function options.More information can be found on the following link: http://msdn2.microsoft.com/en-us/library/ms648002.aspx |
| System.Int32 | x | Specifies the horizontal location of the shortcut menu, in screen coordinates. |
| System.Int32 | y | Specifies the vertical location of the shortcut menu, in screen coordinates. |
| System.Int32 | nReserved | Reserved; must be zero. |
| System.IntPtr | hWnd | Handle to the window that owns the shortcut menu. This window receives all messages from the menu. The window does not receive a WM_COMMAND message from the menu until the function returns. If you specify TPM_NONOTIFY in the uFlags parameter, the function does not send messages to the window identified by hWnd. However, you must still pass a window handle in hWnd. It can be any window handle from your application. |
| System.IntPtr | prcRect | Ignored value. |
Returns
| Type | Description |
|---|---|
| System.Int32 | If you specify TPM_RETURNCMD in the uFlags parameter, the return value is the menu-item identifier of the item that the user selected. If the user cancels the menu without making a selection, or if an error occurs, then the return value is zero. If you do not specify TPM_RETURNCMD in the uFlags parameter, the return value is nonzero if the function succeeds and zero if it fails. To get extended error information, call GetLastError. |
