JFrame un JFrame y quiero esconderme en la taskbar de taskbar (en windows no visibles justo en la parte inferior pero escondidas en los tray menu items la tray menu items ).
¿Alguien puede decirme cómo hacer eso?
¿Debo hacer algunos cambios en la configuración del sistema de windows ?
por ejemplo, es posible que haya visto algunos download managers , team viewer , 4shared desktop , etc. que se ocultan en los elementos del menú de la bandeja de la barra de tareas.
myFrame#getExtendedState y myFrame#setExtendedState
básicamente es mejor multiplicar estos ExtendedStates
frame.setExtendedState(JFrame.ICONIFIED);
frame.setExtendedState(frame.getExtendedState() | JFrame.ICONIFIED);
frame.setExtendedState(JFrame.NORMAL);
frame.setExtendedState(frame.getExtendedState() & (~JFrame.ICONIFIED));
EDITAR 1.
por ejemplo
import java.awt.event.ActionEvent;
import javax.swing.*;
public class WindowGCDemo1 {
private javax.swing.Timer timer = null;
private int count = 0;
private JFrame myFrame = new JFrame();
public WindowGCDemo1() {
myFrame = new JFrame();
myFrame.setLocation(150, 150);
myFrame.setSize(200, 400);
myFrame.setVisible(true);
System.out.println(myFrame.getExtendedState());
start();
}
private void start() {
timer = new javax.swing.Timer(1000, updateCol());
timer.start();
}
public Action updateCol() {
return new AbstractAction("Set Delay") {
private static final long serialVersionUID = 1L;
@Override
public void actionPerformed(ActionEvent e) {
timer.stop();
myFrame.setExtendedState(JFrame.ICONIFIED);
System.out.println(myFrame.getExtendedState());
count++;
startAgain();
}
};
}
private void startAgain() {
timer = new javax.swing.Timer(1000, updateColAgain());
timer.start();
}
public Action updateColAgain() {
return new AbstractAction("Set Delay") {
private static final long serialVersionUID = 1L;
@Override
public void actionPerformed(ActionEvent e) {
timer.stop();
myFrame.setExtendedState(JFrame.NORMAL);
System.out.println(myFrame.getExtendedState());
count++;
if (count > 5) {
timer.stop();
stop();
}
start();
}
};
}
private void stop() {
System.out.println("--------------------------------------------");
System.out.println("System Exit");
System.exit(0);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
WindowGCDemo1 windowGCDemo = new WindowGCDemo1();
}
});
}
}
EDITAR 2.
para SystemTry , debe establecer su JFrame#setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE); y en los JMenuItem (s) correctos de JPopupMenu , solo JFrame#setVisible(true);
