基于WPF系统框架设计(4)-Ribbon整合Avalondock 2.0实现多文档界面设计(一)

前些时间研究了WPF的一些框架，感觉基于Prism框架的MVVM模式对系统的UI与逻辑分离很好，所以就按照之前Winform的框架设计，用WPF做了一套，感觉比Winform要强很多。

MVVM模式和MVC模式一样，主要目的是分离视图（View）和模型（Model），有几大优点

1. 低耦合。视图（View）可以独立于Model变化和修改，一个ViewModel可以绑定到不同的"View"上，当View变化的时候Model可以不变，当Model变化的时候View也可以不变。

2. 可重用性。你可以把一些视图逻辑放在一个ViewModel里面，让很多view重用这段视图逻辑。

3. 独立开发。开发人员可以专注于业务逻辑和数据的开发（ViewModel），设计人员可以专注于页面设计，使用Expression Blend可以很容易设计界面并生成xaml代码。

4. 可测试。界面素来是比较难于测试的，而现在测试可以针对ViewModel来写。

现在我做了个实例，整合模仿Office 2010的Ribbon效果：

(2)Silver

(3)Black

我把框架的View设计和框架设计简单介绍一下。

        public event PropertyChangedEventHandler PropertyChanged;

}

更换主题：提供统一的接口就可以实现整合框架和控件主题更换。

/// <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);//更换主题接口
            this.DataContext = new WorkspaceViewModel();
            this.Loaded += new RoutedEventHandler(MainWindow_Loaded);
            this.Unloaded += new RoutedEventHandler(MainWindow_Unloaded); 
        }
