用Java如何模拟按键动作？

Question

JButton jb=new JButton("Clike_Here");
jb.registerKeyboardAction(new ActionListener() { 
      public void actionPerformed(ActionEvent e) { 
        JOptionPane.showMessageDialog(contentPane,"1234567890"); 
      } 
    },KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,KeyEvent.CTRL_MASK),JComponent.WHEN_IN_FOCUSED_WINDOW);

Answer 1

应该可以，自己fire一个keypress事件。

Answer 2

这是一个响应键盘按键事件的程序
其中KeyEvent.VK_DELETE是delete键，你看怎么样？
this.addKeyListener(new KeyAdapter() {
  public void keyPressed(KeyEvent e) {
    if(e.getKeyCode()==KeyEvent.VK_DELETE)
      removecanvas(e);
  }
});
