C# Winform 让整个窗口都可以拖动
作者：
Windows 的 API 果然强大啊.以前要实现全窗口拖动, 要写鼠标按下和抬起事件, 很是麻烦, 偶尔还会出现 BUG
今天在网上查一些资料的时候, 无意中发现另一种办法, 非常方便, 调用系统的 API 来实现的, 效果也很好. 赶紧收藏了~
[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 void frmMain_MouseDown(object sender, MouseEventArgs e)
{
ReleaseCapture();
SendMessage(this.Handle, 0x0112, 0xF012, 0);
}
复制代码 代码如下:
[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 void frmMain_MouseDown(object sender, MouseEventArgs e)
{
ReleaseCapture();
SendMessage(this.Handle, 0x0112, 0xF012, 0);
}
