how to minimize a window to system tray , and how to restore it from trayIcon's popup menu....???

[Sanjeev Charla]

in a swing application, we add a sysem tray icon to the application... but, how can we minimize the window to notificaiton area instead of normal window minimize operation... we added a pop up menu to tray icon... by handling mouse events we can quit the application by using exit(0) function... but how can we restore a minimized window... please explain... thank you...

Minimizing to tray is quite easy, when you use a WindowListener:

public void windowIconified(WindowEvent e)
{
    setVisible(false);
}

This will really hide the window right after it has been minimized (called iconified in Java).

Restoring is not that different:

int state = getExtendedState();
state = state & ~Frame.ICONIFIED;
setExtendedState(state);
setVisible(true);

The first line retrieves the current state, which is a bitmask. It then sets the ICONIFIED (minimized) part to false, then sets the same state again. This way, if the program was maximized before it will be maximimized again, etc. Of course a setVisible(true) must follow to show the window again.
