Silverlight 布局面板加控件方法
加入文字的方法：
TextBlock txt = new TextBlock();
txt.Text = tmc;
txt.FontSize = 12;
txt.Foreground = t_brush;
txt.FlowDirection = FlowDirection.LeftToRight;
//
double tt_angle = this.GetAngle(eb, ee);
double t_angle = tt_angle;
t_angle = t_angle * 180.0 / this.PI;
if (t_angle >= 360)
{
t_angle -= 360;
}
t_angle = 360 - t_angle; //修正用于顺时针rotate方向
//RotateTransform //SkewTransform
RotateTransform rt = new RotateTransform();
rt.Angle = t_angle; //顺时针rotate方向
rt.CenterX = 0;
rt.CenterY = 0;
txt.RenderTransform = rt;
txt.RenderTransformOrigin = new Point(t_atP.X, t_atP.Y);
//
txt.SetValue(Canvas.LeftProperty, t_atP.X);
txt.SetValue(Canvas.TopProperty, t_atP.Y);
//
this.cRoot.Children.Add(txt);
//----加入直线的方法：
Brush t_brush=new SolidColorBrush(this.LineColor);
//
double p_sx = this.wfView.MapToScreen_X((double)rt_t.SX);
double p_sy = this.wfView.MapToScreen_Y((double)rt_t.SY);
//
double p_ex = this.wfView.MapToScreen_X((double)rt_t.EX);
double p_ey = this.wfView.MapToScreen_Y((double)rt_t.EY);
//
PointD eb = new PointD();
eb.X = (double)rt_t.SX;
eb.Y = (double)rt_t.SY;
PointD ee = new PointD();
ee.X = (double)rt_t.EX;
ee.Y = (double)rt_t.EY;
//画线(用面对象仅仅加入两个点来完毕)
Polygon t_line = new Polygon();
//
t_line.Points.Add(new Point(p_sx, p_sy));
t_line.Points.Add(new Point(p_ex, p_ey));
//
t_line.Points.Add(new Point(p_sx, p_sy));
//
//t_line.StrokeThickness = 2;
//t_line.Opacity = 0.5;
//t_line.Width = 2;
t_line.Stroke = t_brush;
t_line.Fill = t_brush;
//
this.cRoot.Children.Add(t_line); 加入图片和矩形框的方法：
BitmapImage img = new BitmapImage();
img.CreateOptions = BitmapCreateOptions.None;
string path = "/AppSilverlight;component/WorkFlowNodeImageDir/png/" + t;
Stream s = Application.GetResourceStream(new Uri(path, UriKind.Relative)).Stream;
img.SetSource(s);
//
Image ui_img = new Image();
ui_img.Source = img;
//计算节点左上角坐标
double top_x = (int)p_x;
top_x = top_x - img.PixelWidth / 2;
double top_y = (int)p_y;
top_y = top_y - img.PixelHeight / 2;
//
ui_img.SetValue(Canvas.LeftProperty, top_x);
ui_img.SetValue(Canvas.TopProperty, top_y);
this.cRoot.Children.Add(ui_img);
//
//画节点外边框
{
Rectangle rect = new Rectangle();
rect.Stroke = t_Brush;
rect.Fill = new SolidColorBrush(Colors.Transparent);
rect.SetValue(Canvas.LeftProperty, top_x);
rect.SetValue(Canvas.TopProperty, top_y);
rect.Width = img.PixelWidth;
rect.Height = img.PixelHeight;
this.cRoot.Children.Add(rect);
}
}
//加入节点名称
{ //画节点名称
string actmc = rt_act.ACTMC;
TextBlock txt = new TextBlock();
txt.Text = actmc;
txt.FontSize = 12;
txt.Foreground = t_Brush;
char[] longLine = actmc.ToCharArray();
//修正节点名称显示位置
double t_txtLen = longLine.Length / 2.0;
t_txtLen = t_txtLen * txt.FontSize;
//
double x = p_x - t_txtLen;
