Winform窗体缺少左上角效果:
public void SetWindowRegion()
{
System.Drawing.Drawing2D.GraphicsPath FormPath;
FormPath = new System.Drawing.Drawing2D.GraphicsPath();
Rectangle rect = new Rectangle(, , this.Width, this.Height);
int diameter = ;
FormPath .AddRectangle(new Rectangle(rect.Location.X + diameter, rect.Location.Y, rect.Width - diameter, rect.Height));
FormPath .AddRectangle(new Rectangle(rect.Location.X, rect.Location.Y + diameter, diameter, rect.Height - diameter));
path.CloseFigure(); this.Region = new Region(FormPath); } protected override void OnResize(System.EventArgs e)
{ this.Region = null; SetWindowRegion(); }
参考:Winform窗体四圆角效果:
public void SetWindowRegion() { System.Drawing.Drawing2D.GraphicsPath FormPath; FormPath = new System.Drawing.Drawing2D.GraphicsPath(); Rectangle rect = new Rectangle(, , this.Width, this.Height - );//this.Left-10,this.Top-10,this.Width-10,this.Height-10); FormPath = GetRoundedRectPath(rect, ); this.Region = new Region(FormPath); } private GraphicsPath GetRoundedRectPath(Rectangle rect, int radius) { int diameter = radius; Rectangle arcRect = new Rectangle(rect.Location, new Size(diameter, diameter)); GraphicsPath path = new GraphicsPath(); // 左上角 path.AddArc(arcRect, , ); // 右上角 arcRect.X = rect.Right - diameter; path.AddArc(arcRect, , ); // 右下角 arcRect.Y = rect.Bottom - diameter; path.AddArc(arcRect, , ); // 左下角 arcRect.X = rect.Left; path.AddArc(arcRect, , ); path.CloseFigure(); return path; } protected override void OnResize(System.EventArgs e) { this.Region = null; SetWindowRegion(); }
