Examples

The following code example demonstrates how to create a VisualStyleRenderer with the VisualStyleElement returned by the Disabled property. To run this example, paste it into a Windows Form. Handle the form's Paint event and call the DrawVisualStyleElementTrackBarThumb5 method from the Paint event-handling method, passing e as PaintEventArgs.

public void DrawVisualStyleElementTrackBarThumb5(PaintEventArgs e)
{
    if (VisualStyleRenderer.IsElementDefined(
        VisualStyleElement.TrackBar.Thumb.Disabled))
    {
        VisualStyleRenderer renderer =
             new VisualStyleRenderer(VisualStyleElement.TrackBar.Thumb.Disabled);
        Rectangle rectangle1 = new Rectangle(10, 50, 50, 50);
        renderer.DrawBackground(e.Graphics, rectangle1);
        e.Graphics.DrawString("VisualStyleElement.TrackBar.Thumb.Disabled",
             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 DrawVisualStyleElementTrackBarThumb5(ByVal e As PaintEventArgs)
    If (VisualStyleRenderer.IsElementDefined( _
     VisualStyleElement.TrackBar.Thumb.Disabled)) Then
        Dim renderer As New VisualStyleRenderer _
          (VisualStyleElement.TrackBar.Thumb.Disabled)
        Dim rectangle1 As New Rectangle(10, 50, 50, 50)
        renderer.DrawBackground(e.Graphics, rectangle1)
        e.Graphics.DrawString("VisualStyleElement.TrackBar.Thumb.Disabled", _
          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
