示例

下面的代码示例演示如何 VisualStyleRenderer 使用属性返回的来创建 VisualStyleElement DownPressed 。The following code example demonstrates how to create a VisualStyleRenderer with the VisualStyleElement returned by the DownPressed property. 若要运行此示例，请将其粘贴到 Windows 窗体中。To run this example, paste it into a Windows Form. 处理窗体的 Paint 事件，并 DrawVisualStyleElementScrollBarArrowButton7 从 Paint 事件处理方法调用方法，并将 e 作为传递 PaintEventArgs 。Handle the form's Paint event and call the DrawVisualStyleElementScrollBarArrowButton7 method from the Paint event-handling method, passing e as PaintEventArgs.

public void DrawVisualStyleElementScrollBarArrowButton7(PaintEventArgs e)
{
    if (VisualStyleRenderer.IsElementDefined(
        VisualStyleElement.ScrollBar.ArrowButton.DownPressed))
    {
        VisualStyleRenderer renderer =
             new VisualStyleRenderer(VisualStyleElement.ScrollBar.ArrowButton.DownPressed);
        Rectangle rectangle1 = new Rectangle(10, 50, 50, 50);
        renderer.DrawBackground(e.Graphics, rectangle1);
        e.Graphics.DrawString("VisualStyleElement.ScrollBar.ArrowButton.DownPressed",
             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 DrawVisualStyleElementScrollBarArrowButton7(ByVal e As PaintEventArgs)
    If (VisualStyleRenderer.IsElementDefined( _
     VisualStyleElement.ScrollBar.ArrowButton.DownPressed)) Then
        Dim renderer As New VisualStyleRenderer _
          (VisualStyleElement.ScrollBar.ArrowButton.DownPressed)
        Dim rectangle1 As New Rectangle(10, 50, 50, 50)
        renderer.DrawBackground(e.Graphics, rectangle1)
        e.Graphics.DrawString("VisualStyleElement.ScrollBar.ArrowButton.DownPressed", _
          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
