可锚固设备的装载和保存布局.可见性的装订
可锚固设备的装载和保存布局.可见性的装订
提问于 2016-08-16 11:56:49
我面临的问题是，在加载我的旧布局之后，我无法打开X类型的可播性。只有当我在保存布局之前关闭X类型的可选性时，才会发生这种情况。
有人对AvalonDock也有类似的问题吗？这是AvalonDock的错误吗？经过多年的调试，我担心在更改<Setter Property="IsActive" Value="{Binding Model.IsActive, Mode=TwoWay}"/>中的IsActive时，绑定ViewModel无法在视图中得到正确的更新。AvalonDock应该负责这个任务。但也许问题是布局的加载和保存？

视图
我在视图中的Loaded事件中加载可锚定的DockingManager的保存的布局(= tool窗口)，如下所示(简化)：
string savedLayout = Properties.Settings.Default.Layout;
XmlDocument doc = new XmlDocument();
doc.LoadXml(savedLayout);
// very simplified code. load saved xml layout and add anchorables to the dockmanager
doc.SelectNodes("//LayoutAnchorable").OfType<XmlNode>().ToList().ForEach(anchorable =>
{
this.DockManager.AnchorablesSource.Add(anchorable);
});我在视图中的Closing事件中保存可锚定项的当前布局，如下所示(简化)：
XmlDocument doc = new XmlDocument();
XmlLayoutSerializer xmlLayoutSerializer = new XmlLayoutSerializer(this.DockManager);
using (MemoryStream stream = new MemoryStream())
{
xmlLayoutSerializer.Serialize(stream);
stream.Seek(0, SeekOrigin.Begin);
doc.Load(stream);
}
// here happens some magic. i think this code is not responsible for my problem
Properties.Settings.Default.Layout = doc.OuterXml;ViewModel与XAML中的ViewModel绑定如下(简化)：
<xcad:DockingManager x:Name="DockManager" AnchorablesSource="{Binding Tools}" Loaded="DockManager_Loaded">
<xcad:DockingManager.LayoutItemContainerStyle>
<Style TargetType="{x:Type dockctrl:LayoutItem}">
<Setter Property="Title" Value="{Binding Model.ContentId}" />
<Setter Property="IsSelected" Value="{Binding Model.IsSelected, Mode=TwoWay}" />
<Setter Property="CanClose" Value="{Binding Model.CanClose, Mode=TwoWay}" />
<Setter Property="Visibility" Value="{Binding Model.IsVisible, Mode=TwoWay, Converter={StaticResource Bool2vis}, ConverterParameter={x:Static Visibility.Hidden}}"/>
<Setter Property="CloseCommand" Value="{Binding Model.CloseCommand}" />
<Setter Property="IconSource" Value="{Binding Model.IconSource}" />
<Setter Property="IsActive" Value="{Binding Model.IsActive, Mode=TwoWay}"/>
<Setter Property="ContentId" Value="{Binding Model.ContentId}" />
</Style>
</xcad:DockingManager.LayoutItemContainerStyle>
[...]ViewModel
在ViewModel of MainWindow中打开了“可播性”。以下是消息的示例代码：
public ObservableCollection<ToolBoxViewModelBase> Tools { get; } = new ObservableCollection<ToolBoxViewModelBase>();
public MainWindowViewModel()
{
// [...]
this.MessagesWindow = new MessagesWindowViewModel();
SimpleIoc.Default.Register<MessagesWindowViewModel>(() => this.MessagesWindow);
this.ShowMessagesWindowCommand = new RelayCommand(() => this.OpenToolBox(this.MessagesWindow));
// [...]
}
public void OpenToolBox<T>(T viewModel) where T : ToolBoxViewModelBase
{
// [...]
viewModel.IsVisible = true;
viewModel.IsActive = true;
// [...]
}只要让我知道，如果你需要更多的信息，或我是否错过了添加一些代码！

也许我误解了你的问题但是..。IsActive属性不用于打开保存到布局中的工具。该属性用于将工具设置为活动(聚焦)。为了打开保存到布局中的工具，您应该处理附加如下内容的layoutSerializer_LayoutSerializationCallback：
var layoutSerializer = new XmlLayoutSerializer(this.DockManager);
layoutSerializer.LayoutSerializationCallback += layoutSerializer_LayoutSerializationCallback;
protected virtual void layoutSerializer_LayoutSerializationCallback(object sender, LayoutSerializationCallbackEventArgs e)
{
try
{
var model = this.Docs.Union(this.Tools).FirstOrDefault(vm => vm.ContentId == e.Model.ContentId);
if (model != null)
{
e.Content = model;
}
else
{
// Log load layout error info
}
}
catch (Exception ex)
{
// Log load layout error info
}
