在窗体中定义两个变量
Point mouseOff;//鼠标移动位置变量 bool leftFlag;//标签是否为左键窗体的三个鼠标事件
this.MouseMove += new MouseEventHandler(MainWindow_MouseMove); this.MouseDown += new MouseEventHandler(MainWindow_MouseDown); this.MouseUp += new MouseEventHandler(LoginForm_MouseUp);事件代码:
private void MainWindow_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { mouseOff = new Point(-e.X, -e.Y); //得到变量的值 leftFlag = true; //点击左键按下时标注为true; } } private void MainWindow_MouseMove(object sender, MouseEventArgs e) { if (leftFlag) { Point mouseSet = Control.MousePosition; mouseSet.Offset(mouseOff.X, mouseOff.Y); //设置移动后的位置 Location = mouseSet; } } private void LoginForm_MouseUp(object sender, MouseEventArgs e) { if (leftFlag) { leftFlag = false;//释放鼠标后标注为false; } }有了这三个事件就能支持无边框窗体移动了
