判断鼠标双键按下（附键盘组合键）-JSP教程,Jsp/Servlet

帮你查了一下api,其中有段话可能你没注意看：

the button mask returned by inputevent.getmodifiers() reflects only the button that changed state, not the current state of all buttons. (note: due to overlap in the values of alt_mask/button2_mask and meta_mask/button3_mask, this is not always true for mouse events involving modifier keys). to get the state of all buttons and modifier keys, use inputevent.getmodifiersex().

inputevent.getmodifiers()只能反射单个键的更改状态，如果想获得组合键的状态，必须用inputevent.getmodifiersex().

下面的代码我测试过，可以判断：

gtext.addmouselistener(new mouseadapter()

{

public void mousepressed(mouseevent e)

{

if(e.getbutton()==e.button1 )

glabel.settext("button1"); //判断左键

if( e.getbutton()==e.button3)

glabel.settext("button3");//判断右键

if(e.getmodifiersex()==(e.button3_down_mask + e.button1_down_mask))

glabel.settext("bt1+bt3!"); //判断左右键同时按下

if(e.getmodifiersex()==(e.shift_down_mask + e.button1_down_mask))

glabel.settext("shift+bt1");// shift+左键

//……………其他雷同，修改常量值就可以

}

}

);
