Przykłady

Poniższy przykład kodu jest przeznaczony do użycia z formularzami Systemu Windows i wymaga PaintEventArgse, obiektu zdarzenia OnPaint. Kod tworzy ścieżkę, dodaje wiersz do ścieżki, a następnie pobiera ostatni punkt w ścieżce.

private:
   void GetLastPointExample( PaintEventArgs^ /*e*/ )
   {
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->AddLine( 20, 20, 100, 20 );
      PointF lastPoint = myPath->GetLastPoint();
      if ( lastPoint.IsEmpty == false )
      {
         String^ lastPointXString = lastPoint.X.ToString();
         String^ lastPointYString = lastPoint.Y.ToString();
         MessageBox::Show( String::Concat( lastPointXString, ", ", lastPointYString ) );
      }
      else
            MessageBox::Show( "lastPoint is empty" );
   }

private void GetLastPointExample(PaintEventArgs e)
{
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddLine(20, 20, 100, 20);
    PointF lastPoint = myPath.GetLastPoint();
    if(lastPoint.IsEmpty == false)
    {
        string lastPointXString = lastPoint.X.ToString();
        string lastPointYString = lastPoint.Y.ToString();
        MessageBox.Show(lastPointXString + ", " + lastPointYString);
    }
    else
    {
        MessageBox.Show("lastPoint is empty");
    }
}

Public Sub GetLastPointExample(ByVal e As PaintEventArgs)
    Dim myPath As New GraphicsPath
    myPath.AddLine(20, 20, 100, 20)
    Dim lastPoint As PointF = myPath.GetLastPoint()
    If lastPoint.IsEmpty = False Then
        Dim lastPointXString As String = lastPoint.X.ToString()
        Dim lastPointYString As String = lastPoint.Y.ToString()
        MessageBox.Show((lastPointXString + ", " + lastPointYString))
    Else
        MessageBox.Show("lastPoint is empty")
    End If
End Sub
