基於CefSharp開發瀏覽器（八）瀏覽器收藏夾欄

鹹魚翻身？發表於2021-03-02

瀏覽器

一、前言

上一篇文章基於CefSharp開發（七）瀏覽器收藏夾選單簡單實現了部分收藏夾功能如（新增資料夾、新增收藏、刪除、右鍵選單部分功能）

後續程式碼中對MTreeViewItem進行了擴充套件,增加了TextBox用於編輯Item及相應的依賴屬性，實現了重新命名操作。

瀏覽器除了有收藏夾選單，還需要有收藏夾欄用於快捷訪問，本章將開發簡易的收藏夾欄。

二、收藏夾欄分析

如下面兩幅圖所示，前者為收藏夾選單樣式，後者為收藏夾欄樣式，兩者資料結構相同，只是展示形式略有差異。故可採用同一資料結構

觀其展示形式與MMenu接近，故此處將採用Menu進行樣式擴充套件開發。

收藏夾欄支援右鍵功能，故需要新增ContextMenu支援。

收藏夾欄與收藏夾選單展示的同一資料，屬於同一功能，故需增加聯動。

下面將逐步完成以上內容的開發，由於樣式及結構均與收藏夾選單接近，故本章不對樣式進行敘述，直擼程式碼

三、建立自定義控制元件並新增至WebTabControlUc

1、新增定義控制元件MFavorites、MFavoritesItem

樣式可複製MMenu、MMenuItem
