JFrame卡住了，我无法跨过屏幕

Question

I made a frame with some labels and a button on it, created an executable ear and now when i start it i can't move the application on my screen. Sometimes it works, sometimes it doesn't. I just can't drag the thing..

  JFrame frame = new JFrame("Name"); frame.setPreferredSize(new Dimension(260, 160)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JButton exitButton = new JButton("Exit"); exitButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { System.exit(0); } }); frame.add(exitButton, BorderLayout.SOUTH); frame.add(vertBox, BorderLayout.CENTER); frame.setVisible(true); frame.pack(); frame.setLocationRelativeTo(null); 

Any ideas what's wrong? It's really annoying that i can't move it. PS There is a code part that i skipped, where i made the labels and added them

Answer 1

Perhaps (in the code you didn't show) you were disabling your frame through

frame.setEnabled(false);
