I am trying to use it in Windows Forms by encapsulating the above wpf usercontrol in WinForms userControl.... with this code....
public partial class wfUserControl2 : UserControl
{
ElementHost elhost;
WpfControls.UserControl2 wpfUserControl2;
public wfUserControl2()
{
InitializeComponent();
elhost = new ElementHost();
elhost.Size = new Size(new Point(this.Size));
elhost.Dock = DockStyle.Fill;
wpfUserControl2 = new WpfControls.UserControl2();
elhost.Child = wpfUserControl2;
this.Controls.Add(elhost);
}
}It works great. The question is I am unable to set the Region for the Winforms UserControl to contour the shape of the wpf userControl even after exposing the wpfUserControl shape outline as a path...
I want to be able to draw overlapping controls. Without the region set correctly, I can not represent the flow of the process from Point A to Point B. If you see the attached picture, it would make more sense...
The code I have to set the region is...
private void Clip()
{
//get a flattend version of the WPF-Path
PathGeometry pathFlattend = wpf_Clarifier.OuterPath.Data.GetFlattenedPathGeometry();
//get all PathPoints
List<PointF> pts = new List<PointF>();
System.Windows.Point ptStart = (wpf_Clarifier.OuterPath.Data as PathGeometry).Figures[0].StartPoint;
pts.Add(new PointF((float)ptStart.X, (float)ptStart.Y));
foreach (PathFigure f in pathFlattend.Figures)
{
for (int l = 0; l < f.Segments.Count; l++)
{
if (f.Segments[l] is PolyLineSegment)
{
PolyLineSegment b = (PolyLineSegment)f.Segments[l];
for (int i = 0; i < b.Points.Count; i++)
{
pts.Add(new PointF((float)b.Points[i].X, (float)b.Points[i].Y));
}
}
}
}
//and pathTypes
List<byte> types = new List<byte>();
types.Add(0);
for (int i = 1; i < pts.Count - 1; i++)
types.Add(1);
types.Add(129);
//create a new gdi+ GraphicsPath
using (GraphicsPath gP = new GraphicsPath(pts.ToArray(), types.ToArray()))
{
////transform to the actual Location of the wpf-UserControl in the WinForms-UserControl
//gP.Transform(new System.Drawing.Drawing2D.Matrix(1, 0, 0, 1,
// elhost.Bounds.X,
// elhost.Bounds.Y));
//and assign the region
this.Region = new Region(gP);
}
}
In the WPF UserContro2.cs file I have the following property to expose myPath as OuterPath...
public Path OuterPath
{
get
{
return (Path)myPath;
}
}I need to know where I should call the Clip() in winforms userControl code so that when I draw it on WinForm it would consume space to its shape....
Any idea?
Thanks
