Avalon Dock 自动隐藏面板将不会重新打开

Question

我有一个使用 Xceed Avalon Dock 2.0 的 .NET 6.0 程序。我将“AnchorableSource”设置为 ViewModel 的

BindableCollection

，并且当前集合中只有一个视图模型。我的问题是，当我自动隐藏面板时，它会折叠到底部，但当我单击标题时它不会重新打开。

折叠为：

但是当我单击“工具”时没有任何反应。

我不确定在哪里放置断点，或者是否可以在后面添加一些代码来捕获单击并重新打开。 我有另一个项目使用相同的东西，并且它重新打开得很好。

这是我的代码：

Answer 1

这是因为您的窗口将AllowsTransparency 设置为True。 AvalonDock 不支持此功能。我也在寻找解决方案。
