How to minimize a JFrame window from Java?

In my Java app, I have a JFrame window, how can I 开发者_Go百科minimize it from my Java program ?

---

minimize with frame.setState(Frame.ICONIFIED)

restore with frame.setState(Frame.NORMAL)

---

Minimize:

frame.setState(Frame.ICONIFIED);

Another way to minimize:

frame.setExtendedState(JFrame.ICONIFIED);

Normal size:

frame.setState(Frame.NORMAL);

Another way to normal size:

frame.setExtendedState(JFrame.NORMAL);

Maximize:

frame.setState(Frame.MAXIMIZED_BOTH);

Another way to maximize:

frame.setExtendedState(JFrame.MAXIMIZED_BOTH);

Full Screen maximize:

GraphicsDevice device = GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices()[0];
try { device.setFullScreenWindow((Window) frame); } finally { device.setFullScreenWindow(null); }

Refer to the JFrame documentation for more information.

You can do this in two ways:

JFrame frame = new JFrame("Test");

frame.setExtendedState(JFrame.ICONIFIED); // One way
frame.setState(JFrame.ICONIFIED); // Another way

---

Another approach

frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_ICONIFIED));

---

You can use following code:

this.setState(YourJFrame.ICONIFIED);

And you can use this code to maximize it:

this.setExtendedState(MAXIMIZED_BOTH);

---

If you are trying to code for a event of a component then try code below. And make sure the class which this code is included is extended by Frame class

private void closeMouseClicked(java.awt.event.MouseEvent evt){                        
    this.setState(1);
}

Or create an instance of a Frame class and call setState(1);
