LayoutAnchorGroup Class

Represents an autohidden group of one or more LayoutAnchorable elements that can be anchored to one of the four sides of the DockingManager.

Syntax

Visual Basic
C#

'Declaration
 
<ContentPropertyAttribute("Children")>
<TypeDescriptionProviderAttribute(MS.Internal.ComponentModel.DependencyObjectProvider)>
<NameScopePropertyAttribute("NameScope", System.Windows.NameScope)>
<SerializableAttribute()>
Public Class LayoutAnchorGroup 
   Inherits Xceed.Wpf.AvalonDock.Layout.LayoutGroup(Of LayoutAnchorable)
   Implements ILayoutContainer, ILayoutElement, ILayoutGroup

'Usage
 
Dim instance As LayoutAnchorGroup

[ContentProperty("Children")]
[TypeDescriptionProvider(MS.Internal.ComponentModel.DependencyObjectProvider)]
[NameScopeProperty("NameScope", System.Windows.NameScope)]
[Serializable()]
public class LayoutAnchorGroup : Xceed.Wpf.AvalonDock.Layout.LayoutGroup<LayoutAnchorable>, ILayoutContainer, ILayoutElement, ILayoutGroup

Remarks

To use LayoutAnchorGroup, add LayoutAnchorable elements to it, and add the resulting LayoutAnchorGroup to an instance of LayoutAnchorSide. The resulting LayoutAnchorSide is then assigned to a "Side" property (e.g., LeftSide, TopSide) of the LayoutRoot object held in the Layout property of DockingManager.

AvalonDock adheres to an MVVM design.

The Model is represented by the classes contained in the Xceed.Wpf.AvalonDock.Layout namespace. The classes in this namespace are the layout elements in a layout model (for example LayoutAnchorable/LayoutDocument, LayoutAnchorablePane/LayoutDocumentPane, LayoutAnchorablePaneGroup/LayoutDocumentPaneGroup, etc.) that are used directly in XAML within a DockingManager to describe how the layout is composed.

The View is represented by the classes contained in the Xceed.Wpf.AvalonDock.Controls namespace; these classes are a set of stylizable controls that show the user controls. The names of the view controls typically end with "Control" (for example, LayoutAnchorableControl is the view control, whereas LayoutAnchorable is the model element).

The DockingManager uses various classes (such as the LayoutItem and its derived classes) to perform the role of the ViewModel, preparing the model to be consumed by the view.

There is one and only one logical tree, which has the DockingManager as its root. Even if a control is placed in a different window (i.e., autohidden windows or floating windows), it always belong to the same logical tree below the DockingManager.

Example

The following shows how to use autohidden windows, as well as various other elements.
