- When their position changes, sends a message back to the main window. The main window reposition the taskbar and tray.
- The position is calculated by enumerating all the child windows of the shell bar, taking account of hidden windows.
- Creates a tray icon.
- Only supports horizontal shell bar.
- Sometimes the position is not calculated correctly, where the right side of the tray is covered by the task bar.
