来源： 基于CefSharp开发浏览器（八）浏览器收藏夹栏 – 咸鱼翻身？ – 博客园

一、前言

上一篇文章 基于CefSharp开发（七）浏览器收藏夹菜单 简单实现了部分收藏夹功能 如（添加文件夹、添加收藏、删除、右键菜单部分功能）

后续代码中对MTreeViewItem进行了扩展,增加了TextBox用于编辑Item及相应的依赖属性，实现了重命名操作。

浏览器除了有收藏夹菜单，还需要有收藏夹栏用于快捷访问，本章将开发简易的收藏夹栏。

二、收藏夹栏分析

如下面两幅图所示，前者为收藏夹菜单样式，后者为收藏夹栏样式，两者数据结构相同，只是展示形式略有差异。故可采用同一数据结构

观其展示形式与MMenu接近，故此处将采用Menu进行样式扩展开发。

收藏夹栏支持右键功能，故需要添加ContextMenu支持。

收藏夹栏与收藏夹菜单展示的同一数据，属于同一功能，故需增加联动。

下面将逐步完成以上内容的开发，由于样式及结构均与收藏夹菜单接近，故本章不对样式进行叙述，直撸代码

三、创建自定义控件并添加至WebTabControlUc

1、新增定义控件MFavorites、MFavoritesItem

样式可复制MMenu、MMenuItem

该类中的方法用于初始化MFavorites数据

3、更改WebTabControlUc布局

新增一行用于展示FavoritesBarUc

<webBrowser:FavoritesBarUc Grid.Row="2"/>

四、运行效果

五、源码地址
