PRB: Menus for Notification Icons Don't Work CorrectlyLast reviewed: September 20, 1996Article ID: Q135788 |
The information in this article applies to:
SYMPTOMSWhen 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.
RESOLUTIONTo 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_NULL, 0, 0); STATUSThis behavior is by design.
