我目前正忙于开发无边界WinForms表单,而我刚从here获得了一些代码。我根据自己的需要对其进行了修改,但现在遇到了麻烦。我将如何限制其调整大小?
当前,我可以调整窗口大小,使其仅是屏幕上的一个点。如何在最小尺寸上加一个“上限”?
以下是用于调整大小的代码片段(应按原样工作):
//Initializes the form
public Form1()
{
InitializeComponent();
this.DoubleBuffered = true;
this.SetStyle(ControlStyles.ResizeRedraw, true);
}
private const int cGrip = 16; // Grip size
private const int cCaption = 32; // Caption bar height;
//Overides what happens everytime the form is drawn
protected override void OnPaint(PaintEventArgs e)
{
//Draws a border with defined width
int width = 1;
Pen drawPen = new Pen(titleBar.BackColor, width);
e.Graphics.DrawRectangle(drawPen, new Rectangle(width / 2, width / 2, this.Width - width, this.Height - width));
drawPen.Dispose();
//Draws the resizer grip
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.Coral, rc);
}
//Handles windows messages
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);
}
请注意,我不是一个经验丰富的C#程序员。我以前在C#中唯一的经验是在Unity中编程,因此,如果您能给我详细说明您可能拥有的解决方案的话,将不胜感激。

无论表单是否是无边界的,您仍然可以使用MinimumSize
和MaximumSize
属性。
尝试一下:
public Form1()
{
InitializeComponent();
this.DoubleBuffered = true;
this.SetStyle(ControlStyles.ResizeRedraw, true);
this.MinimumSize = new Size(200, 200);
this.MaximumSize = new Size(800, 600);
}
