我终于开始实现这个功能,我使用了 AvalonDock 2.0,它对 MVVM 很友好。我需要做的就是TabControl
用 a替换DockingManager
并修改几个Style
s。
设置(DockingManager
我只有文件,没有工具等):
<avalonDock:DockingManager x:Name="tabDesigner" DocumentsSource="{Binding Items}">
<avalonDock:DockingManager.LayoutItemContainerStyle>
<Style TargetType="{x:Type avalonDockControls:LayoutItem}" BasedOn="{StaticResource DocumentItem}"/>
</avalonDock:DockingManager.LayoutItemContainerStyle>
<avalonDock:DockingManager.DocumentPaneControlStyle>
<Style TargetType="{x:Type avalonDockControls:LayoutDocumentPaneControl}" BasedOn="{StaticResource DocumentPane}"/>
</avalonDock:DockingManager.DocumentPaneControlStyle>
<avalonDockLayout:LayoutRoot>
<avalonDockLayout:LayoutPanel Orientation="Horizontal">
<avalonDockLayout:LayoutDocumentPane/>
</avalonDockLayout:LayoutPanel>
</avalonDockLayout:LayoutRoot>
</avalonDock:DockingManager>
我不需要使用 AvalonDock 的模板选择器,我可以使用DataTemplate
已经为之前的TabControl
.
我修改了LayoutItem
,LayoutDocumentPaneControl
和LayoutDocumentTabItem
Style
s 以对视图模型和其他布局差异进行额外绑定(花了一些时间才弄清楚如何绑定到 AvalonDock 模型中的视图模型):
<Style x:Key="DocumentItem" TargetType="{x:Type avalonDockControls:LayoutItem}">
<Setter Property="Title" Value="{Binding Model.TabTitle}"/>
<Setter Property="CloseCommand" Value="{Binding Model.CloseConfirmCommand}"/>
<Setter Property="IsSelected" Value="{Binding Model.IsSelected, Mode=TwoWay}"/>
</Style>
<Style x:Key="DocumentPane" TargetType="{x:Type avalonDockControls:LayoutDocumentPaneControl}">
...
<Setter Property="Template">

这是最终结果的示例:
