自定义xp风格工具栏
代码实现如下：
需要注意的地方是从ToolBar继承的自定义控件不能直接override它的OnPaint函数，必须在它的construct函数设置它的外观由用户绘制，定义代码如下：
this.SetStyle(ControlStyles.UserPaint,true);
/// <summary>
/// 实现XP风格的工具栏按钮

private Color borderColorHover = Color.Navy;
private Color fillDownColor = Color.RosyBrown;
private Color borderDownColor = Color.SeaGreen;
public ToolBarXP(System.ComponentModel.IContainer container)
{
///

///

//

//

}
