The following code example demonstrates how to create a VisualStyleRenderer with the VisualStyleElement returned by the Normal property. To run this example, paste it into a Windows Form. Handle the form’s Paint event and call the DrawVisualStyleElementTrackBarThumbVertical1 method from the Paint event-handling method, passing e as PaintEventArgs.
public void DrawVisualStyleElementTrackBarThumbVertical1(PaintEventArgs e) { if (VisualStyleRenderer.IsElementDefined( VisualStyleElement.TrackBar.ThumbVertical.Normal)) { VisualStyleRenderer renderer = new VisualStyleRenderer(VisualStyleElement.TrackBar.ThumbVertical.Normal); Rectangle rectangle1 = new Rectangle(10, 50, 50, 50); renderer.DrawBackground(e.Graphics, rectangle1); e.Graphics.DrawString("VisualStyleElement.TrackBar.ThumbVertical.Normal", 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)); }
