我有这段代码运行没有任何错误,但它没有按我计划的方式运行。我试图弄清楚为什么当我单击标有“重要!!”的按钮时没有显示我的“继续”按钮。
唯一显示的是一个空白弹出窗口,它是代码 JDialog 的一部分,它设置为模态且可见。我就是想不通。如果有人可以帮助我,我将不胜感激。
JPanel hehePanel = new JPanel(new FlowLayout(FlowLayout.RIGHT,10,20));
JDialog dialog = new JDialog((JFrame)null);
dialog.getContentPane().add(hehePanel,BorderLayout.CENTER);
JButton hButton = new JButton("important!!");
JButton fButton = new JButton(" on construction !!");
JButton exitButton = new JButton("EXIT CAW ");
hehePanel.add(hButton);
hButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
final JPanel hehePanel = new JPanel();
final JDialog dialog = new JDialog();
dialog.getContentPane().add(hehePanel,BorderLayout.PAGE_END);
dialog.toFront();
dialog.setModal(true);
dialog.pack();
dialog.setLocationRelativeTo(null);
dialog.setVisible(true);
JButton closebutton = new JButton("Continue");
closebutton.setActionCommand("continue");
closebutton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
if (evt.getActionCommand().equals("continue")) {
dialog.dispose();
}
}
});
hehePanel.add(closebutton);
}
});
hehePanel.add(fButton);
hehePanel.add(exitButton);
