Örnekler

Aşağıdaki kod örneği Windows Forms ile kullanılmak üzere tasarlanmıştır ve bir PaintEventArgs olay nesnesi olan eOnPaint gerektirir. Kod bir yol oluşturur, yola bir çizgi ekler ve ardından yolun son noktasını alır.

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