  • 基于CefSharp开发浏览器(八)浏览器收藏夹栏

    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
