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 : PaintEventArgs
14 {
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 MouseOver
33 {
34 get { return _mouseOver; }
35 }
36
37 public bool MousePress
38 {
39 get { return _mousePress; }
40 }
41
42 public bool MouseInUpButton
43 {
44 get { return _mouseInUpButton; }
45 }
46 }
47 }

TabControl组件的代码
1 #region 为TabControl添加关闭按钮
2 const int CLOSE_SIZE = 15;
3 //关闭按钮功能
4 private void MainTabControl_MouseDown(object sender, MouseEventArgs e)
5 {
6 if (tabContent.SelectedTab.Name != "tabPageWelcome")
7 {
8 if (e.Button == MouseButtons.Left)
9 {
10 int x = e.X, y = e.Y;
11 //计算关闭区域
12 Rectangle myTabRect = this.tabContent.GetTabRect(this.tabContent.SelectedIndex);
13
14 myTabRect.Offset(myTabRect.Width - (CLOSE_SIZE + 3), 2);
15 myTabRect.Width = CLOSE_SIZE;
16 myTabRect.Height = CLOSE_SIZE;
17
18 //如果鼠标在区域内就关闭选项卡
19 bool isClose = x > myTabRect.X && x < myTabRect.Right && y > myTabRect.Y && y < myTabRect.Bottom;
20 if (isClose == true)
21 {
22 this.tabContent.TabPages.Remove(this.tabContent.SelectedTab);
23 }
24 }
25 }
26 }
27 #endregion
