c# – 带有棱镜区域适配器的AvalonDock

概述我已经看到了一些关于SO的问题,但它们似乎都不适用于我.我希望能够使用带有Prism 4的伟大的 Avalondock 2.0.但是,所有的样本区域适配器都是针对Avalondock 1.x系列,我无法让它工作. 有没有人有关于如何为AvalonDock的LayoutDocumentPane和LayoutAnchorablePane创建Region Adapter的示例代码？ 不幸的是,据我所知, 我已经看到了一些关于SO的问题,但它们似乎都不适用于我.我希望能够使用带有Prism 4的伟大的 Avalondock 2.0.但是,所有的样本区域适配器都是针对Avalondock 1.x系列,我无法让它工作.

有没有人有关于如何为AvalonDock的LayoutdocumentPane和LayoutAnchorablePane创建Region Adapter的示例代码？

解决方法 不幸的是,据我所知,“LayoutdocumentPane”和“LayoutAnchorablePane”都不允许包含/创建regionadapters,但是“DockingManager”会这样做.一种解决方案是为DockingManager创建regionadapter,然后管理可视树中“Layoutdocuments”的实例化.

xaml看起来如下：

<ad:DockingManager Background="AliceBlue" x:name="WorkspaceRegion" prism:RegionManager.Regionname="WorkspaceRegion">                        <ad:LayoutRoot>                            <ad:LayoutPanel>                                <ad:LayoutdocumentPaneGroup>                                    <ad:LayoutdocumentPane>                                    </ad:LayoutdocumentPane>                                </ad:LayoutdocumentPaneGroup>                            </ad:LayoutPanel>                        </ad:LayoutRoot>                    </ad:DockingManager>

请注意,该区域在DockingManager标记中定义,并且LayoutPanel下存在一个LayoutdocumentPaneGroup. LayoutdocumentPaneGroup下的LayoutdocumentPane将托管与要添加到“WorkspaceRegion”的视图关联的Layoutdocuments.

至于regionadapter本身,请参考下面的代码,我提供了解释性注释

不要忘记在bootstrapper中添加以下代码,以便Prism知道regionadapter的存在

protected overrIDe regionadapterMapPings ConfigureregionadapterMapPings()        {            // Call base method            var mapPings = base.ConfigureregionadapterMapPings();            if (mapPings == null) return null;            // Add custom mapPings            mapPings.RegisterMapPing(typeof(DockingManager),ServiceLocator.Current.GetInstance<AvalonDockregionadapter>());            // Set return value            return mapPings;        }

瞧.我知道这不是最干净的解决方案,但应该有效.同样的方法可以很容易地应用于“LayoutAnchorablePane”.

健康长寿·繁荣昌盛！
