Esempio

L'esempio di codice seguente è progettato per l'uso con Windows Forms e richiede PaintEventArgs e, un OnPaint oggetto evento. Il codice esegue le azioni seguenti:

• Crea un percorso.

• Aggiunge diverse figure aperte al percorso.

• Chiude tutte le figure nel percorso.

• Disegna il percorso dello schermo.
