4月7日 滑动解锁

滑动解锁用到了3个鼠标事件，MouseDown按下鼠标时发生，MouseUp松开鼠标时发生，MouseMove按下又松开时发生

1、滑动解锁                                    2、解锁之后的页面                           3、页面滑动切换

           

1、定义两个成员变量

//判断是否按下鼠标
      private bool mousedown;

      //记录按下时X坐标
      private int CurX;

2、滑动解锁代码

//当按下鼠标时 
     private void button1_MouseDown(object sender, MouseEventArgs e) 
       { 
           //当鼠标按下时 mousedown 设置为 true 
            mousedown=true; 
         //记录一下当前X坐标 
           CurX = Cursor.Position.X; 
       } 
       //鼠标松开时 
       private void button1_MouseUp(object sender, MouseEventArgs e) 
       { 
           //当鼠标移动超过50时，解锁成功 
           if (Cursor.Position.X - CurX > 50) 
           { 
               panel3.Visible = false; 
           } 
           else 
           { 
               //没有超过50则返回原位置 
               button1.Location = new Point(30,180); 
           } 
           //松开鼠标时，mousedown设为false 
           mousedown = false; 
       } 
       //鼠标按下又松开时 
       private void button1_MouseMove(object sender, MouseEventArgs e) 
       { 
           //记录一下当前鼠标滑动到什么位置 
           int curnowx = Cursor.Position.X; 
           if (mousedown) 
           { 
               button1.Location = new Point(30+curnowx-CurX,180); 
           } 
       } 

3、切换页面代码

//鼠标按下时 
    private void panel1_MouseDown(object sender, MouseEventArgs e) 
    { 
        //当鼠标按下时 mousedown 设置为 true 
        mousedown = true; 
        CurX =Cursor.Position.X; 
    } 
    //鼠标松开时 
    private void panel1_MouseUp(object sender, MouseEventArgs e) 
    { 
        //当鼠标移动超过30时 
        if (Cursor.Position.X - CurX < -30) 
        { 
            panel1.Location = new Point(-280, 0); 
            panel2.Location = new Point(0, 0); 
        } 
        else 
        { 
            panel1.Location = new Point(0,0); 
            panel2.Location = new Point(280,0); 
        } 
        mousedown = false; 
    } 
    //鼠标按下再松开时 
    private void panel1_MouseMove(object sender, MouseEventArgs e) 
    { 
        int curnowx=Cursor.Position.X; 
        if (mousedown) 
        { 
            panel1.Location = new Point(0+curnowx-CurX,0); 
            panel2.Location = new Point(280+curnowx-CurX,0); 
        } 
    } 
   private void panel2_MouseDown(object sender, MouseEventArgs e) 
    { 
        mousedown = true; 
        CurX = Cursor.Position.X; 
    } 
    private void panel2_MouseUp(object sender, MouseEventArgs e) 
    { 
         if (Cursor.Position.X - CurX > 30) 
        { 
            panel1.Location = new Point(0, 0); 
            panel2.Location = new Point(280, 0); 
        } 
        else 
        { 
            panel1.Location = new Point(-280, 0); 
            panel2.Location = new Point(0, 0); 
        } 
        mousedown = false; 
    } 
    private void panel2_MouseMove(object sender, MouseEventArgs e) 
    { 
        int curnowx=Cursor.Position.X; 
        if (mousedown) 
        { 
            panel1.Location = new Point(-280+curnowx-CurX,0); 
            panel2.Location = new Point(curnowx -CurX, 0); 
        } 
    }
