判断鼠标双击

步调代码:import java.applet.*;import java.awt.*;import java.awt.event.*;public class dbclick extends applet implements mouselistener { boolean isdoubleclick = false; // 能否双击标记 public void init() { addmouselistener(this); // 举行鼠标事变监听 } public void paint(graphics g) { g.drawstring("请单击或双击鼠标", 10,10); if(isdoubleclick) g.drawstring("您双击了鼠标",10,30); else g.drawstring(" ",10,30); // 废除表露双击消息 } 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; // 贯串扭打度数为2,则证明是双击了鼠标 repaint(); }}证明:所谓双击,本来即是确定了贯串扭打鼠标键的度数,您不妨把度数改成3,4,5...试试看:),再有,在往日的jdk中,简直本子不领会,是没有getclickcount()因变量的,不妨用两次点击鼠标键的功夫间隙来确定能否在指定的范畴内.本来道理即是如许.
