RoundcornerForm 圓角窗口

HuronControl.RoundcornerForm()

功能：圓角窗口（WinForm，無邊框窗口最佳）。

該控件繼承自System.Windows.Forms

 

代碼：

public RoundcornerForm()  
{  
    this.Paint += new PaintEventHandler(RoundcornerForm_Paint);  
}  
  
private void RoundcornerForm_Paint(object sender, PaintEventArgs e)  
{  
    List<Point> list = new List<Point>();  
    int width = this.Width;  
    int height = this.Height;  
  
    //左上   
    list.Add(new Point(0, 5));  
    list.Add(new Point(1, 5));  
    list.Add(new Point(1, 3));  
    list.Add(new Point(2, 3));  
    list.Add(new Point(2, 2));  
    list.Add(new Point(3, 2));  
    list.Add(new Point(3, 1));  
    list.Add(new Point(5, 1));  
    list.Add(new Point(5, 0));  
  
    //右上   
    list.Add(new Point(width - 5, 0));  
    list.Add(new Point(width - 5, 1));  
    list.Add(new Point(width - 3, 1));  
    list.Add(new Point(width - 3, 2));  
    list.Add(new Point(width - 2, 2));  
    list.Add(new Point(width - 2, 3));  
    list.Add(new Point(width - 1, 3));  
    list.Add(new Point(width - 1, 5));  
    list.Add(new Point(width - 0, 5));  
  
    //右下   
    list.Add(new Point(width - 0, height - 5));  
    list.Add(new Point(width - 1, height - 5));  
    list.Add(new Point(width - 1, height - 3));  
    list.Add(new Point(width - 2, height - 3));  
    list.Add(new Point(width - 2, height - 2));  
    list.Add(new Point(width - 3, height - 2));  
    list.Add(new Point(width - 3, height - 1));  
    list.Add(new Point(width - 5, height - 1));  
    list.Add(new Point(width - 5, height - 0));  
  
    //左下   
    list.Add(new Point(5, height - 0));  
    list.Add(new Point(5, height - 1));  
    list.Add(new Point(3, height - 1));  
    list.Add(new Point(3, height - 2));  
    list.Add(new Point(2, height - 2));  
    list.Add(new Point(2, height - 3));  
    list.Add(new Point(1, height - 3));  
    list.Add(new Point(1, height - 5));  
    list.Add(new Point(0, height - 5));  
  
    Point[] points = list.ToArray();  
  
    GraphicsPath shape = new GraphicsPath();  
    shape.AddPolygon(points);  
  
    this.Region = new System.Drawing.Region(shape);  
}

實例：

 

　

仿Apple半透明Loading控件

窗口構造

// WinForm 實例 frmFlag   
  
private LoadingCircle loadingCircle = new HuronControl.LoadingCircle();  
  
// loadingCircle   
this.loadingCircle.BackColor = System.Drawing.Color.DimGray;  
this.loadingCircle.InnerCircleRadius = 15;  
this.loadingCircle.LineWidth = 3;  
this.loadingCircle.Name = "loadingCircle";  
this.loadingCircle.OutnerCircleRadius = 40;  
this.loadingCircle.Speed = 100;  
this.loadingCircle.SpokesMember = 15;  
this.loadingCircle.ThemeColor = System.Drawing.Color.White;  
  
// frmFlag   
this.BackColor = System.Drawing.Color.DimGray;  
this.Controls.Add(this.loadingCircle);  
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;  
this.MaximizeBox = false;  
this.MinimizeBox = false;  
this.Name = "frmFlag";  
this.Opacity = 0.8D;  
this.ShowIcon = false;  
this.TopMost = true;  

控制方法

int steps = 100; //總步數   
int step = 0; //當前進度   
  
//步進方式   
//步進開始   
loadingCircle.StartStep(steps);  
//步進到...(建議配合線程或Timer使用)   
loadingCircle.PerformStep(step);  
  
//循環方式   
loadingCircle1.StartMarquee();  

注：若使用線程控制loadingCircle步進，需要使用委託，類似如下

this.BeginInvoke(new EventHandler(PerformStep));
