Examples

The following code example demonstrates the effects of setting the StartCap and EndCap properties on a Pen.

This example is designed to be used with Windows Forms. Paste the code into a form and call the ShowStartAndEndCaps method when handling the form's Paint event, passing e as PaintEventArgs.

private:
   void ShowStartAndEndCaps( PaintEventArgs^ e )
   {
      // Create a new custom pen.
      Pen^ redPen = gcnew Pen( Brushes::Red,6.0F );

      // Set the StartCap property.
      redPen->StartCap = System::Drawing::Drawing2D::LineCap::RoundAnchor;

      // Set the EndCap property.
      redPen->EndCap = System::Drawing::Drawing2D::LineCap::ArrowAnchor;

      // Draw a line.
      e->Graphics->DrawLine( redPen, 40.0F, 40.0F, 145.0F, 185.0F );

      // Dispose of the custom pen.
      delete redPen;
   }

private void ShowStartAndEndCaps(PaintEventArgs e)
{

    // Create a new custom pen.
    Pen redPen = new Pen(Brushes.Red, 6.0F);

    // Set the StartCap property.
    redPen.StartCap = System.Drawing.Drawing2D.LineCap.RoundAnchor;

    // Set the EndCap property.
    redPen.EndCap = System.Drawing.Drawing2D.LineCap.ArrowAnchor;

    // Draw a line.
    e.Graphics.DrawLine(redPen, 40.0F, 40.0F, 145.0F, 185.0F);

    // Dispose of the custom pen.
    redPen.Dispose();
}

Private Sub ShowStartAndEndCaps(ByVal e As PaintEventArgs)

    ' Create a new custom pen.
    Dim redPen As New Pen(Brushes.Red, 6.0F)

    ' Set the StartCap property.
    redPen.StartCap = Drawing2D.LineCap.RoundAnchor

    ' Set the EndCap property.
    redPen.EndCap = Drawing2D.LineCap.ArrowAnchor

    ' Draw a line.
    e.Graphics.DrawLine(redPen, 40.0F, 40.0F, 145.0F, 185.0F)

    ' Dispose of the custom pen.
    redPen.Dispose()

End Sub
