SWT SYSTEM TRAY can only handle three events: Left click, left click, right click, right-click this is what I see SWT 3.0.1 Win32 source code, this DEMO has the following functions: 1. Left button When you click, hide, display the main window 2. Right-click, pop-up menu Note: 1. Left button Double-click and right click to double-click an event, no distinguish 2. Left button will produce the following event: Left click, left Key Double click, left click on 3. About the pop-up menu, Menu must have a Parent, if there is no shell in the program, you can build an invisible shell as a Menu's Parent.
