public class dbclick extends Applet implements MouseListener  
{
  boolean isDoubleClick = false;  // 是否雙擊標(biāo)志

  public void init()
  {
    addMouseListener(this);   // 進(jìn)行鼠標(biāo)事件監(jiān)聽
  }

  public void paint(Graphics g)
  {
    g.drawString("請(qǐng)單擊或雙擊鼠標(biāo)", 10,10);
    if(isDoubleClick)
      g.drawString("您雙擊了鼠標(biāo)",10,30);
    else
      g.drawString("            ",10,30);  // 清除顯示雙擊信息
  }

  public void mousePressed(MouseEvent e) {}
  public void mouseReleased(MouseEvent e) {}
  public void mouseEntered(MouseEvent e) {}
  public void mouseExited(MouseEvent e) {}
  public void mouseClicked(MouseEvent e)
  {
    isDoubleClick = e.getClickCount() == 2;  // 連續(xù)擊打次數(shù)為2,則說明是雙擊了鼠標(biāo)
    repaint();
  }
}
說明:所謂雙擊,其實(shí)就是判斷了連續(xù)擊打鼠標(biāo)鍵的次數(shù),您可以把次數(shù)改成3,4,5...試試看:),還有,在以前的JDK中,具體版本不知道,是沒有g(shù)etClickCount()函數(shù)的,可以用兩次點(diǎn)擊鼠標(biāo)鍵的時(shí)間間隔來判斷是否在指定的范圍內(nèi).其實(shí)原理就是這樣.
