It usually displays an + * icon or an animated icon there. The icon represents + * the application, similar to a taskbar button, but consumes less + * screen space. + * + * When the user clicks with the left mouse button on the icon, the + * main application window is shown/raised and activated. With the + * right mouse button, she gets a popupmenu with application specific + * commands, including "Minimize/Restore" and "Quit". + * + * Docking happens magically when calling show(). The window undocks + * with either hide() or when it is destroyed. + * + * KSystemTray inherits methods such as setPixmap() and setMovie() to + * specify an icon or movie (animated icon) respectively. It is + * designed to be usable "as is", without the need to subclass it. In + * case you need to provide something special (such as an additional + * popupmenu on a click with the left mouse button), you can subclass + * anyway, of course. + * + * Having an icon on the system tray is a useful technique for + * daemon-like applications that may run for some time without user + * interaction but have to be there immediately when the user needs + * them. Examples are kppp, kisdn, kscd, kmix or knotes. With kppp and + * kisdn, the docked icon even provides real-time information about + * the network status. + * + * @author Matthias Ettrich <[email protected]> + **/ +class KDEUI_EXPORT KSystemTray : public TQLabel +{ + Q_OBJECT +public: + + /** + * Construct a KSystemTray widget just like any other widget. + * + * The parent widget @p parent has a special meaning: + * Besides owning the tray window, the parent widget will + * dissappear from taskbars when it is iconified while the tray + * window is visible.
