C#的TabControl模拟IE7程序事例,带关闭功能

在csdn下载了一个类似ie7的功能，使用的是默认的TabControl控件 窗体算比较丑 功能是实现了 废话不多说 贴代码

1：先上图

2：贴代码

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

namespace WindowsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

int isclicktwo = 0;

private void tabControl1_MouseUp(object sender, MouseEventArgs e)

{

if (this.tabControl1.SelectedIndex == 0) return;

if (e.Button == MouseButtons.Right)

{

for (int i = 1; i < tabControl1.TabPages.Count; i++)

{

TabPage tp = tabControl1.TabPages[i];

if (tabControl1.GetTabRect(i).Contains(new Point(e.X, e.Y)))

{

tabControl1.SelectedTab = tp;

this.contextMenuStrip1.Show(this.tabControl1, new Point(e.X, e.Y));

break;

}

}

}

if (e.Button == MouseButtons.Left)

{

isclicktwo++;

Rectangle myTabRect = this.tabControl1.GetTabRect(this.tabControl1.SelectedIndex);

int width = myTabRect.Width / 4;

int height=myTabRect .Height ;

Rectangle closeRect = new Rectangle(myTabRect.X, myTabRect.Y, width, height);

if (closeRect.Contains(new Point(e.X, e.Y)))

{

if(isclicktwo >=2)

{

this.tabControl1.TabPages.Remove(this.tabControl1.SelectedTab);

isclicktwo = 0;

}

}

}

}

private void 关闭ToolStripMenuItem_Click(object sender, EventArgs e)

{

this.tabControl1.TabPages.Remove(this.tabControl1.SelectedTab);

}

private void Form1_Load(object sender, EventArgs e)

{

}

private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)

{

for (int i = 1; i < this.tabControl1.TabPages.Count; i++)

{

if(this.tabControl1.TabPages [i].ImageIndex!=-1)

{

this.tabControl1.TabPages[i].ImageIndex = -1;

}

}

if (this.tabControl1.SelectedIndex == 0) return;

this.tabControl1.SelectedTab .ImageIndex =0;

isclicktwo = 0;//转换页清零

}

private void tabControl1_MouseDown(object sender, MouseEventArgs e)

{

if (this.tabControl1.SelectedIndex == 0) return;

if (e.Button == MouseButtons.Left)

{

Rectangle myTabRect = this.tabControl1.GetTabRect(this.tabControl1.SelectedIndex);

int width = myTabRect.Width / 4;

int height = myTabRect.Height;

Rectangle closeRect = new Rectangle(myTabRect.X, myTabRect.Y, width, height);

if (closeRect.Contains(new Point(e.X, e.Y)))

{

this.tabControl1.TabPages[this.tabControl1.SelectedIndex].ImageIndex = 1;

Application.DoEvents();

}

}

}

private void tabControl1_MouseLeave(object sender, EventArgs e)

{

if (this.tabControl1.SelectedIndex == 0) return;

this.tabControl1.TabPages[this.tabControl1.SelectedIndex].ImageIndex = 0;

}

}

}

功能还需完善 思路已出
