Esempio

L'esempio seguente è progettato per l'uso con Windows Form e richiede PaintEventArgse, un oggetto evento Paint. Il codice esegue le azioni seguenti:

• Crea un limite di riga personalizzato utilizzando l'oggetto GraphicsPath.

• Crea un oggetto CustomLineCap, firstCap, usando l'oggetto GraphicsPath appena creato.

• Crea un clone di firstCap utilizzando il metodo Clone.

• Imposta le proprietà CustomStartCap e CustomEndCap dell'oggetto Pen e usa tale penna per disegnare una linea e i estremità personalizzati sullo schermo.

Public Sub CloneExample(e As PaintEventArgs)
 Dim points As Point() = New Point(- 5, - 5) New Point(0, 0) _
 New Point(5, - 5)
 Dim capPath As New GraphicsPath()
 ' Create a Path and add two lines to it,
 ' forming a custom line cap.
 capPath.AddLines(points)
 ' Create a CustomLineCap object.
 Dim firstCap As New CustomLineCap(Nothing, capPath)
 ' Create a copy of firstCap.
 Dim secondCap As CustomLineCap = CType(firstCap.Clone(), _
 CustomLineCap)
 ' Create a Pen object.
 Dim pen As New Pen(Color.Black, 3F)
 'Set up the line.
 Dim point1 As New Point(20, 20)
 Dim point2 As New Point(100, 100)
 ' Set up the caps.
 pen.CustomStartCap = firstCap
 pen.CustomEndCap = secondCap
 ' Draw the line and caps to the screen.
 e.Graphics.DrawLine(pen, point1, point2)
 End Sub
