如何移動和調整沒有邊框的表單？

Question

有沒有人知道我沒有邊框時如何調整WinForm的大小。我不想Windows的默認邊框，所以我將屬性「FormBorderStyle」更改爲「無」。這刪除了邊框，但現在它不能調整大小。我已經想出瞭如何移動窗體，我只需要知道如何調整窗體大小。

Answer 1

即允許移動和縮放表格一些示例代碼：

public partial class Form1 : Form { 
    public Form1() { 
     InitializeComponent(); 
     this.FormBorderStyle = FormBorderStyle.None; 
     this.DoubleBuffered = true; 
     this.SetStyle(ControlStyles.ResizeRedraw, true); 
    } 
    private const int cGrip = 16;  // Grip size 
    private const int cCaption = 32; // Caption bar height; 

    protected override void OnPaint(PaintEventArgs e) { 
     Rectangle rc = new Rectangle(this.ClientSize.Width - cGrip, this.ClientSize.Height - cGrip, cGrip, cGrip); 
     ControlPaint.DrawSizeGrip(e.Graphics, this.BackColor, rc); 
     rc = new Rectangle(0, 0, this.ClientSize.Width, cCaption); 
     e.Graphics.FillRectangle(Brushes.DarkBlue, rc); 
    } 

    protected override void WndProc(ref Message m) { 
     if (m.Msg == 0x84) { // Trap WM_NCHITTEST 
     Point pos = new Point(m.LParam.ToInt32()); 
     pos = this.PointToClient(pos); 
     if (pos.Y < cCaption) { 
      m.Result = (IntPtr)2; // HTCAPTION 
      return; 
     } 
     if (pos.X >= this.ClientSize.Width - cGrip && pos.Y >= this.ClientSize.Height - cGrip) { 
      m.Result = (IntPtr)17; // HTBOTTOMRIGHT 
      return; 
     } 
     } 
     base.WndProc(ref m); 
    } 
    } 

Answer 2

如果您刪除了邊框，您還要刪除內置功能來調整框架的大小。有辦法避開它，但你必須建立自己的功能來拖拽和調整邊框的大小。

//第一U最添加這個類

      Right = _Right && (right_left_Area); if (Right) return "r";

進而形成CS

     }

     private const int cCaption = 32; // Caption bar height; 

     protected override void OnPaint(PaintEventArgs e)

      //this if you want to draw (if) 

      Color theColor = Color.FromArgb(10, 20, 20, 20);

下面是與調整的全部8個點的自定義格式的完整的例子：

public partial class Form1 : Form { 
public Form1() { 
    InitializeComponent(); 
    this.FormBorderStyle = FormBorderStyle.None; // no borders 
    this.DoubleBuffered = true; 
    this.SetStyle(ControlStyles.ResizeRedraw, true); // this is to avoid visual artifacts 
} 

protected override void OnPaint(PaintEventArgs e) // you can safely omit this method if you want 
{ 
    e.Graphics.FillRectangle(Brushes.Green, Top); 
    e.Graphics.FillRectangle(Brushes.Green, Left); 
    e.Graphics.FillRectangle(Brushes.Green, Right); 
    e.Graphics.FillRectangle(Brushes.Green, Bottom); 
} 

private const int 
    HTLEFT = 10, 
    HTRIGHT = 11, 
    HTTOP = 12, 
    HTTOPLEFT = 13, 
    HTTOPRIGHT = 14, 
    HTBOTTOM = 15, 
    HTBOTTOMLEFT = 16, 
    HTBOTTOMRIGHT = 17; 

const int _ = 10; // you can rename this variable if you like 

Rectangle Top { get { return new Rectangle(0, 0, this.ClientSize.Width, _); } } 
Rectangle Left { get { return new Rectangle(0, 0, _, this.ClientSize.Height); } } 
Rectangle Bottom { get { return new Rectangle(0, this.ClientSize.Height - _, this.ClientSize.Width, _); } } 
Rectangle Right { get { return new Rectangle(this.ClientSize.Width - _, 0, _, this.ClientSize.Height); } } 

Rectangle TopLeft { get { return new Rectangle(0, 0, _, _); } } 
Rectangle TopRight { get { return new Rectangle(this.ClientSize.Width - _, 0, _, _); } } 
Rectangle BottomLeft { get { return new Rectangle(0, this.ClientSize.Height - _, _, _); } } 
Rectangle BottomRight { get { return new Rectangle(this.ClientSize.Width - _, this.ClientSize.Height - _, _, _); } } 


protected override void WndProc(ref Message message) 
{ 
    base.WndProc(ref message); 

    if (message.Msg == 0x84) // WM_NCHITTEST 
    { 
     var cursor = this.PointToClient(Cursor.Position); 

     if (TopLeft.Contains(cursor)) message.Result = (IntPtr)HTTOPLEFT; 
    else if (TopRight.Contains(cursor)) message.Result = (IntPtr)HTTOPRIGHT; 
    else if (BottomLeft.Contains(cursor)) message.Result = (IntPtr)HTBOTTOMLEFT; 
    else if (BottomRight.Contains(cursor)) message.Result = (IntPtr)HTBOTTOMRIGHT; 

    else if (Top.Contains(cursor)) message.Result = (IntPtr)HTTOP; 
    else if (Left.Contains(cursor)) message.Result = (IntPtr)HTLEFT; 
    else if (Right.Contains(cursor)) message.Result = (IntPtr)HTRIGHT; 
    else if (Bottom.Contains(cursor)) message.Result = (IntPtr)HTBOTTOM; 
    } 
}}
