【java SWT界面的托盘显示】
//点击关闭或者最小化时程序不会退出而是显示到托盘中 当然也可以是显示在任务栏中的
public class TrayApp {
public static void main(String[] args) {
Display display = new Display();
final Shell shell = new Shell(display);
shell.setText("最小化到系統托盤");
//取消系統中預設的圖標,預設圖標在托盤不能顯示
shell.setImage(display.getSystemImage(SWT.ICON_INFORMATION));
//構建系統托盤
final Tray tray = display.getSystemTray();
final TrayItem trayItem = new TrayItem(tray, SWT.NONE);
//設置在托盤中顯示的程序圖標
trayItem.setImage(display.getSystemImage(SWT.ICON_INFORMATION));
//程序啟動時,窗口是顯示的,所以托盤圖標隱藏
trayItem.setVisible(false);
trayItem.setToolTipText(shell.getText());
trayItem.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
toggleDisplay(shell, tray);
}
});
final Menu trayMenu = new Menu(shell, SWT.POP_UP);

//在托盤圖標點擊鼠標右鍵時的事件,彈出系統菜單
trayItem.addMenuDetectListener(new MenuDetectListener() {

}
});
//注冊窗口監聽
