WinForm无边框窗体移动方法
C#WinForm无边框窗体移动方法、模仿鼠标单击标题栏移动窗体位置
这里介绍俩种办法
方法一:直接通过修改窗体位置从而达到移动窗体的效果
方法二:直接伪装发送单击任务栏消息,让应用程序误以为单击任务栏从而移动窗体
新建窗体用于测试
方法一
1.定义一个位置信息Point用于存储鼠标位置
1 private Point mPoint;
2.给窗体等控件增加MouseDown和MouseMove事件
/// <summary> /// 鼠标按下 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void panel1_MouseDown(object sender, MouseEventArgs e) { mPoint = new Point(e.X, e.Y); } /// <summary> /// 鼠标移动 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void panel1_MouseMove(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { this.Location = new Point(this.Location.X + e.X - mPoint.X, this.Location.Y + e.Y - mPoint.Y); } }
方法二:
1.引入下面代码 前提需要引入命名空间using System.Runtime.InteropServices
[DllImport("user32.dll")] public static extern bool ReleaseCapture(); [DllImport("user32.dll")] public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam); private const int VM_NCLBUTTONDOWN = 0XA1;//定义鼠标左键按下 private const int HTCAPTION = 2;
2.增加鼠标按下事件发送消息,让系统误以为按下是标题栏
/// <summary> /// 鼠标按下 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void panel1_MouseDown(object sender, MouseEventArgs e) { //为当前应用程序释放鼠标捕获 ReleaseCapture(); //发送消息 让系统误以为在标题栏上按下鼠标 SendMessage((IntPtr)this.Handle, VM_NCLBUTTONDOWN, HTCAPTION, 0); }
