问题描述
有谁知道我如何在没有边框的情况下调整 winform 的大小.我不想要 Windows 的默认边框,所以我将属性FormBorderStyle"更改为None".这删除了边框,但现在无法调整它的大小.我已经知道如何移动表单了,我只需要知道如何调整它的大小.
Does anyone know how I can resize a winform when it has no border. I don't want the default border that Windows has, so I changed the property "FormBorderStyle" to "None". This removed the border, although now it can't be resized. I've figured out how to move the form around, I just need to know how to resize it.
推荐答案
一些允许移动和调整表单大小的示例代码:
Some sample code that allow moving and resizing the form:
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);
}
}
