  • WPF之换肤

    WPF之换肤

    设计原理

    WPF换肤的设计原理，利用资源字典为每种皮肤资源添加不同的样式，在后台切换皮肤资源文件。

    截图

    上图中，第一张图采用规则样式，第二张图采用不规则样式，截图的时候略有瑕疵。

    资源字典

    规则样式资源Skin.RegularStyle.xaml

    　　仔细观察上面定义的样式，你会发现在定义Window样式的时候指定了Key，其他的Control样式却没有指定Key。大家都知道，如果没有给Style指定Key，那么这个Style会应用到所有目标类型(TargetType)为指定类型的Control。请看下面一段文字：

    因为在换肤的过程中，需要动态加载Window的样式，所以用DynamicResource作绑定Style="{DynamicResource WindowStyle}"。

    App.xaml

    程序运行的时候，默认加载规则样式的皮肤。
