示例

下面的代码示例演示如何使用 VisualStyleElement 属性返回的 Pressed 创建 VisualStyleRenderer 。 若要运行此示例，请将其粘贴到 Windows 窗体中。 处理窗体的事件Paint，并从Paint事件处理方法调用 DrawVisualStyleElementWindowVerticalScroll3 方法，作为 ePaintEventArgs传递。

public void DrawVisualStyleElementWindowVerticalScroll3(PaintEventArgs e)
{
    if (VisualStyleRenderer.IsElementDefined(
        VisualStyleElement.Window.VerticalScroll.Pressed))
    {
        VisualStyleRenderer renderer =
             new VisualStyleRenderer(VisualStyleElement.Window.VerticalScroll.Pressed);
        Rectangle rectangle1 = new Rectangle(10, 50, 50, 50);
        renderer.DrawBackground(e.Graphics, rectangle1);
        e.Graphics.DrawString("VisualStyleElement.Window.VerticalScroll.Pressed",
             this.Font, Brushes.Black, new Point(10, 10));
    }
    else
        e.Graphics.DrawString("This element is not defined in the current visual style.",
             this.Font, Brushes.Black, new Point(10, 10));
}

Public Sub DrawVisualStyleElementWindowVerticalScroll3(ByVal e As PaintEventArgs)
    If (VisualStyleRenderer.IsElementDefined( _
     VisualStyleElement.Window.VerticalScroll.Pressed)) Then
        Dim renderer As New VisualStyleRenderer _
          (VisualStyleElement.Window.VerticalScroll.Pressed)
        Dim rectangle1 As New Rectangle(10, 50, 50, 50)
        renderer.DrawBackground(e.Graphics, rectangle1)
        e.Graphics.DrawString("VisualStyleElement.Window.VerticalScroll.Pressed", _
          Me.Font, Brushes.Black, New Point(10, 10))
    Else
        e.Graphics.DrawString("This element is not defined in the current visual style.", _
          Me.Font, Brushes.Black, New Point(10, 10))
    End If
End Sub
