  最近因项目需要 所以就到网上找了一个美化过的TabControl控件   只不过这个控件没有实现TabPage的关闭功能 所以就自己添加了一个关闭功能

好了废话不多说 

直接贴代码

UpDownButtonPaintEventArgs 类的代码

 1 using System; 2 using System.Collections.Generic; 3 using System.Text; 4 using System.Windows.Forms; 5 using System.Drawing; 6  7 namespace StyleWinForm.TabControls 8 { 9     public delegate void UpDownButtonPaintEventHandler(10         object sender,11         UpDownButtonPaintEventArgs e);12 13     public class UpDownButtonPaintEventArgs : PaintEventArgs14     {15         private bool _mouseOver;16         private bool _mousePress;17         private bool _mouseInUpButton;18 19         public UpDownButtonPaintEventArgs(20             Graphics graphics,21             Rectangle clipRect,22             bool mouseOver,23             bool mousePress,24             bool mouseInUpButton)25             : base(graphics, clipRect)26         {27             _mouseOver = mouseOver;28             _mousePress = mousePress;29             _mouseInUpButton = mouseInUpButton;30         }31 32         public bool MouseOver33         {34             get { return _mouseOver; }35         }36 37         public bool MousePress38         {39             get { return _mousePress; }40         }41 42         public bool MouseInUpButton43         {44             get { return _mouseInUpButton; }45         }46     }47 }

NativeMethods 类的代码
