一个可移动的无Border父窗体类

       在Winform编程中可能我们会觉得windows自己的窗体样式有点丑，想要好看一些的，可是我们将窗体边框隐藏之后又发现窗体没办法移动，这时我们就需要自己做一些操作，让鼠标不管点着窗体什么地方都可以移动窗体。

       我的做法时做一个父窗体，其他需要无边框可移动的窗体都继承它，请看代码

/// <summary> /// 一个可移动窗体无Border父窗体类 /// /// </summary> public partial class FormParent : Form { public FormParent() { InitializeComponent(); } //鼠标拖动变量 protected bool isMouseDown = false; protected Point FormLocation; protected Point mouseOffset; //鼠标按下时记录窗体位置 protected void FormParent_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { isMouseDown = true; FormLocation = this.Location; mouseOffset = Control.MousePosition; } } //鼠标移动时改变窗体位置 protected void FormParent_MouseMove(object sender, MouseEventArgs e) { int x = 0; int y = 0; if (isMouseDown) { Point pt = Control.MousePosition; x = mouseOffset.X - pt.X; y = mouseOffset.Y - pt.Y; this.Location = new Point(FormLocation.X - x, FormLocation.Y - y); } } //鼠标松开后释放窗体跟随 protected void FormParent_MouseUp(object sender, MouseEventArgs e) { isMouseDown = false; } private void pictureBox1_Click(object sender, EventArgs e) { this.Close(); } }
