Özel durumlar

Örnekler

Aşağıdaki kod örneği Windows Forms ile kullanılmak üzere tasarlanmıştır ve Paint olay işleyicisinin bir parametresi olan PaintEventArgsegerektirir. Kod aşağıdaki eylemleri gerçekleştirir:

  • Siyah kalem oluşturur.

  • Çokgen köşeleri için yedi noktadan oluşan bir dizi oluşturur.

  • Çokgeni ekrana çizer.
