Shell_NotifyIconGetRect is . Windows knows exactly where it drew your icon; this API simply returns that truth.
RECT rcIcon; HRESULT hr = Shell_NotifyIconGetRect(&nii, &rcIcon); For classic NIM_ADD via NOTIFYICONDATA , set guidItem = Guid
The guidItem field is optional. For icons added with NOTIFYICONIDENTIFIER_FLAGS.NIIF_USER or similar, you may need it. For classic NIM_ADD via NOTIFYICONDATA , set guidItem = Guid.Empty .
Since Shell_NotifyIconGetRect is a specific Windows API function used to find the screen coordinates of a notification area (system tray) icon, a "helpful feature" would be a utility that allows developers to visually verify that they are retrieving the correct coordinates.
// Helper function to draw a rectangle on the screen (overlay) void VisualizeRect(RECT rc, COLORREF color, int durationMs) DCX_LOCKWINDOWUPDATE);
The function is a specialized Windows Shell API that retrieves the screen coordinates (bounding rectangle) of a specific notification area icon. Introduced with Windows 7 , this function is essential for developers who need to anchor custom UI elements, such as flyout windows or "rich" status popups, directly to their system tray icon.
