基於WPF系統框架設計(4)-Ribbon整合Avalondock 2.0實現多文檔界面設計(一)

前些時間研究了WPF的一些框架，感受基於Prism框架的MVVM模式對系統的UI與邏輯分離很好，因此就按照以前Winform的框架設計，用WPF作了一套，感受比Winform要強不少。

MVVM模式和MVC模式同樣，主要目的是分離視圖（View）和模型（Model），有幾大優勢

1. 低耦合。視圖（View）能夠獨立於Model變化和修改，一個ViewModel能夠綁定到不一樣的"View"上，當View變化的時候Model能夠不變，當Model變化的時候View也能夠不變。

2. 可重用性。你能夠把一些視圖邏輯放在一個ViewModel裏面，讓不少view重用這段視圖邏輯。

3. 獨立開發。開發人員能夠專一於業務邏輯和數據的開發（ViewModel），設計人員能夠專一於頁面設計，使用Expression Blend能夠很容易設計界面並生成xaml代碼。

4. 可測試。界面素來是比較難於測試的，而如今測試能夠針對ViewModel來寫。

如今我作了個實例，整合模仿Office 2010的Ribbon效果：

(1)Blue:

(2)Silver

(3)Black

我把框架的View設計和框架設計簡單介紹一下。

更換主題：提供統一的接口就能夠實現整合框架和控件主題更換。

/// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : RibbonWindow
    {
        public static DockingManager DockingManager;

        public MainWindow()
        {
            InitializeComponent();
            DockingManager = dockManager;
            ThemeManager.ChangeTheme(dockManager, ThemeStyle.Black);//更換主題接口
            this.DataContext = new WorkspaceViewModel();
            this.Loaded += new RoutedEventHandler(MainWindow_Loaded);
            this.Unloaded += new RoutedEventHandler(MainWindow_Unloaded); 
        }
