Exemplos

O exemplo a seguir foi projetado para uso com o Windows Forms e requer PaintEventArgse, um objeto de evento Paint. O código executa as seguintes ações:

• Cria um limite de linha personalizado usando o objeto GraphicsPath.

• Cria um objeto CustomLineCap, firstCap, usando o objeto GraphicsPath que acabou de ser criado.

• Cria um clone de firstCap usando o método Clone.

• Configura as propriedades CustomStartCap e CustomEndCap do objeto Pen e usa essa caneta para desenhar uma linha e as tampas personalizadas na tela.

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

 // Create a copy of firstCap.

 // Create a Pen object.
 Pen pen = new Pen(Color.Black, 3.0f);
 // Set up the line.
 Point point1 = new Point(20, 20);

 // Set up the caps.
