更改WinForm边框的样式？

Question

是否可以更改WinForm边框的样式？我知道如果删除了边框，它将失去调整程序大小的功能。因此有没有办法改变它的风格，但保持它的可调整大小？

Answer 1

您寻求的并不简单，因为边框是由操作系统绘制的。不过，CodePlex上有一个库可以做到这一点。

Drawing Custom Borders in Windows Forms

Answer 2

我不认为有一个直接的方式来做到这一点。

但是，您可以将窗体边框样式设置为无。 并在您的表单中实施调整大小（我认为它不是很难）

string position = String.Empty; 
Point mouseDownPosition = new Point(); 

private void myForm_MouseDown(object sender, MouseEventArgs e) 
{ 
    position = (e.X == 0) ? "Left" : ((e.X == myForm.Width) ? "Right" : String.Empty; 
    position += (e.Y == 0) ? "Top" : ((e.Y == myForm.Height) ? "Bottom" : String.Empty; 
    if(position != String.Empty) 
    { 
     mouseDownPosition = e.Location; 
    } 
} 

private void myForm_MouseMove(object sender, MouseEventArgs e) 
{ 
    if(position != String.Empty) 
    {   
     Point movementOffset = new Point(e.Location.X - mouseDownPosition.X, e.Location.Y - mouseDownPosition.Y); 
     Switch(position) 
     { 
      Case "LeftTop": 
       myForm.Location.X += movementOffset.X; 
       myForm.Location.Y += movementOffset.Y; 
       myForm.Width -= movementOffset.X; 
       myForm.Height -= movementOffset.Y; 
      Case "Left": 
       myForm.Location.X += movementOffset.X; 
       myForm.Width -= movementOffset.X; 
      // Complete the remaining please :) 
     } 
    } 
} 

private void myForm_MouseUp(object sender, MouseEventArgs e) 
{ 
    position = String.Empty; 
} 

PS：还没有测试它

希望你已经设置FormBorderStyle为None

先写这在InitializeComponent（）：

public const int WM_NCLBUTTONDOWN = 0xA1; 
public const int HT_RIGHT = 0xB; 

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; 

[DllImport("user32.dll")] 
public static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam); 
[DllImport("user32.dll")] 
public static extern bool ReleaseCapture(); 

this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.Resize_Form); 

然后，使用类似于此的方法。在这种情况下，我的方式是从右侧只可调整大小的，但应该很容易让来自任何方面的调整：因为游标不再对大小光标变化，当你移动

private void Resize_Form(object sender, MouseEventArgs e) 
    { 
     if ((e.Button == MouseButtons.Left) && (MousePosition.X >= this.Location.X + formWidth - 10)) 
     { 
      System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.SizeWE; 
      ReleaseCapture(); 
      SendMessage(Handle, WM_NCLBUTTONDOWN, HT_RIGHT, 0); 
      formWidth = this.Width; 
     } 
    }
