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);
