去掉边框
this.FormBorderStyle = FormBorderStyle.None;
方法一:
Point mouseOff;//鼠标移动位置变量
bool leftFlag;//标签是否为左键 private void Form1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
mouseOff = new Point(-e.X, -e.Y);
leftFlag = true;
}
} private void Form1_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 Form1_MouseUp(object sender, MouseEventArgs e)
{
if (leftFlag)
{
leftFlag = false;//释放鼠标后标注为False
} }
方法二:调用非托管的动态链接库,通过控件的鼠标按下事件(MouseDown)发送一个拖动的消息,可以给控件添加MouseDown事件后,拖动这个控件来移动窗体
[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]
public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
public const int WM_SYSCOMMAND = 0x0112;
public const int SC_MOVE = 0xF010;
public const int HTCAPTION = 0x0002; private void Form1_MouseDown(object sender, MouseEventArgs e)
{
ReleaseCapture();
SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
}
方法三:通过重载消息处理实现。重写窗口过程(WndProc),处理一些非客户区消息(WM_NCxxxx),C#中重写窗口过程不用再调用SetWindowLong API,直接override一个WndProc就可以了,不用声明api函数。
鼠标的拖动只对窗体本身有效,不能在窗口的控件区域电机拖动
protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
if (m.Msg == 0x84)
{
switch (m.Result.ToInt32())
{
case 1:
m.Result = new IntPtr(2);
break;
}
}
}
方法四:直接在控件上写事件,主窗体设置无边框,让一个panel或PictureBox停靠在主窗体
