Tray Icons and Popup Menus

Environment: VC++ 4.2b, NT 4.0

I'm having difficulty doing a proper popup-menu in response to a click on
my icon in the system tray. The menu is created okay and works perfectly
_if_ I select an item from the menu. However, clicking outside the menu
does *not* dismiss the menu as one would expect.

Relevant code:
--------------
 CPoint pt;
 GetCursorPos( &pt );

 CMenu mnu;
 VERIFY( mnu.LoadMenu( IDR_MAINFRAME ) );

 CMenu* pMenu = mnu.GetSubMenu( 0 );
 ASSERT( NULL != pMenu );

 pMenu->TrackPopupMenu( TPM_RIGHTALIGN|TPM_RIGHTBUTTON, pt.x, pt.y, this,
NULL );


I've also tried the following with the same results:
+ Calling TrackPopupMenu API directly
+ Passing a pointer to an empty rect instead of NULL
+ Passing a pointer to a non-empty rect instead of NULL
+ Using the "OnContextMenu" code generated by Component Gallery instead of
the above
+ Shouting obscenities

Any ideas?

John,
You must first make the owner window the foreground window.  My code looks like:
	::SetForegroundWindow(m_hWnd);  
	pMenu->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON,
					mouse.x,
					mouse.y,
					this,
					NULL);

Check out KB article Q135788.

Found the answer. It _is_ in the KB -- under Win32 SDK. Q135788.

Did you have checked \MSDEV\SAMPLES\SDK\WIN95\TRAYNOT sample from M=
SDEV ? It works OK.

Hi,

I just ran accross this last week, see the kb article Q135788 which is
in the vc4.2 help, just search for the number.  Basically it says:

The second problem is caused by a problem with TrackPopupMenu. It is
necessary to force a task switch to the application that called
TrackPopupMenu at some time in the near future. This can be
accomplished  by posting a benign message to the window or thread.
 
The following code will take care of all of this:
 
   SetForegroundWindow(hDlg);
 
   // Display the menu
   TrackPopupMenu(   hSubMenu,
                     TPM_RIGHTBUTTON,
                     pt.x,
                     pt.y,
                     0,
                     hDlg,
                     NULL);
 
   PostMessage(hDlg, WM_USER, 0, 0);
 


This should make it work as expected.

Hi John,
Add at the top of your relevant code a call to the SetForegroundWindow =
() function.

If you have a default selection in response to a double click on the =
icon of the system tray, I would like to remember you that Microsoft =
suggest to bold it in the popup-menu.
You can do this using the:
::SetMenuDefaultItem (pMenu->GetSafeHmenu (), ID_YOURDEFAULTITEM, =
FALSE);

The information in this article applies to:
  - Microsoft Win32 Application Programming Interface (API) included
with:
     - Microsoft Windows 95 version 4.0

SYMPTOMS
========
 
When you display a context menu for a Notify Icon (see
Shell_NotifyIcon),
clicking anywhere besides the menu or the window that created the menu
(if
it is visible) doesn't cause the menu to disappear. When this behavior
is
corrected, the second time this menu is displayed, it displays and then
immediately disappears.
 
RESOLUTION
==========
 
To correct the first behavior, you need to make the current window the
foreground window before calling TrackPopupMenu or TrackPopupMenuEx.
 
The second problem is caused by a problem with TrackPopupMenu. It is
necessary to force a task switch to the application that called
TrackPopupMenu at some time in the near future. This can be
accomplished by
posting a benign message to the window or thread.
 
The following code will take care of all of this:
 
   SetForegroundWindow(hDlg);
 
   // Display the menu
   TrackPopupMenu(   hSubMenu,
                     TPM_RIGHTBUTTON,
                     pt.x,
                     pt.y,
                     0,
                     hDlg,
                     NULL);
 
   PostMessage(hDlg, WM_USER, 0, 0);
 
STATUS
======
 
This behavior is by design.

I, too, have had the same problem. If you find a solution, please let me

There's a "bug"  (Microsoft calls it a feature) in Windows 95 that requires
calling
SetForegroundWindow before calling your menu. To find out more, search for
Q135788 in MSDN.
This code should work:

  CMenu* pMenu = mnu.GetSubMenu( 0 );
  ASSERT( NULL != pMenu );
  CPoint mouse;
  GetCursorPos(&mouse);
   ::SetForegroundWindow(m_hWnd);  //m_hWnd is the handle to your main
window  
   ::TrackPopupMenu(pMenu->m_hMenu, 0, mouse.x, mouse.y, 0,
       m_hWnd, NULL);
