Java - displaying a minimal JFrame window

Question

If the JFrame window is minimized, is there a way to bring it back into focus?

I am trying to get him to click on a specific point, and then restore it.

while (isRunning) { start = System.currentTimeMillis(); frame.setState(Frame.ICONIFIED); robot.mouseMove(clickX, clickY); robot.mousePress(InputEvent.BUTTON1_MASK); frame.setState(Frame.NORMAL); Thread.sleep(clickMs - (System.currentTimeMillis() - start)); } 

Answer 1

If you want to return it from iconified , you can simply set its state to normal :

 JFrame frame = new JFrame(...); // Show the frame frame.setVisible(true); // Sleep for 5 seconds, then minimize Thread.sleep(5000); frame.setState(java.awt.Frame.ICONIFIED); // Sleep for 5 seconds, then restore Thread.sleep(5000); frame.setState(java.awt.Frame.NORMAL); 

An example from here .

There are also WindowEvent s that fire every time the state changes, and the WindowListener that handles these triggers. In this case you can use:

 public class YourClass implements WindowListener { ... public void windowDeiconified(WindowEvent e) { // Do something when the window is restored } } 

If you want to check for another change in the state of the program, there is no “pure Java” solution, but just an ID window.

You can set the state to normal:

 frame.setState(NORMAL); 

Full example:

 public class FrameTest extends JFrame { public FrameTest() { final JFrame miniFrame = new JFrame(); final JButton miniButton = new JButton( new AbstractAction("Minimize me") { public void actionPerformed(ActionEvent e) { miniFrame.setState(ICONIFIED); } }); miniFrame.add(miniButton); miniFrame.pack(); miniFrame.setVisible(true); add(new JButton(new AbstractAction("Open") { public void actionPerformed(ActionEvent e) { miniFrame.setState(NORMAL); miniFrame.toFront(); miniButton.requestFocusInWindow(); } })); pack(); setDefaultCloseOperation(EXIT_ON_CLOSE); setVisible(true); } public static void main(String[] args) { new FrameTest(); } }
