Events

Name	Type	Summary
ArrangeInvalidated	EventHandler	Occurs when the arrange state (layout) has been invalidated.
MeasureInvalidated	EventHandler	Occurs when the measurement state (layout) has been invalidated.
PropertyChanged	EventHandler<AvaloniaPropertyChangedEventArgs>	Raised when a `AvaloniaProperty` value changes on this object. Inherited from AvaloniaObject

Properties

Name	Value	Summary
InheritanceParent	IAvaloniaObject	Gets or sets the parent object that inherited `AvaloniaProperty` values are inherited from. Inherited from AvaloniaObject
LayoutId	string
this[AvaloniaProperty]	object	Gets or sets the value of a `AvaloniaProperty`. Inherited from AvaloniaObject
this[IndexerDescriptor]	IBinding	Gets or sets a binding for a `AvaloniaProperty`. Inherited from AvaloniaObject

Methods

Name	Value	Summary
Arrange(LayoutContext, Size)	Size	Positions child elements and determines a size for a container UIElement. Container elements that support attached layouts should call this method from their layout override implementations to form a recursive layout update.
BeginBatchUpdate()	void	Inherited from AvaloniaObject
Bind<T>(DirectPropertyBase<T>, IObservable<BindingValue<T>>)	IDisposable	Binds a `AvaloniaProperty` to an observable. Inherited from AvaloniaObject
Bind<T>(StyledPropertyBase<T>, IObservable<BindingValue<T>>, BindingPriority)	IDisposable	Binds a `AvaloniaProperty` to an observable. Inherited from AvaloniaObject
CheckAccess()	bool	Inherited from AvaloniaObject
ClearValue(AvaloniaProperty)	void	Clears a `AvaloniaProperty`'s local value. Inherited from AvaloniaObject
ClearValue<T>(AvaloniaProperty<T>)	void	Clears a `AvaloniaProperty`'s local value. Inherited from AvaloniaObject
ClearValue<T>(DirectPropertyBase<T>)	void	Clears a `AvaloniaProperty`'s local value. Inherited from AvaloniaObject
ClearValue<T>(StyledPropertyBase<T>)	void	Clears a `AvaloniaProperty`'s local value. Inherited from AvaloniaObject
CoerceValue<T>(StyledPropertyBase<T>)	void	Coerces the specified `AvaloniaProperty`. Inherited from AvaloniaObject
EndBatchUpdate()	void	Inherited from AvaloniaObject
Equals(object)	bool	Compares two objects using reference equality. Inherited from AvaloniaObject
GetBaseValue<T>(StyledPropertyBase<T>, BindingPriority)	Optional<T>	Gets an `AvaloniaProperty` base value. Inherited from AvaloniaObject
GetHashCode()	int	Gets the hash code for the object. Inherited from AvaloniaObject
GetValue(AvaloniaProperty)	object	Gets a `AvaloniaProperty` value. Inherited from AvaloniaObject
GetValue<T>(DirectPropertyBase<T>)	T	Gets a `AvaloniaProperty` value. Inherited from AvaloniaObject
GetValue<T>(StyledPropertyBase<T>)	T	Gets a `AvaloniaProperty` value. Inherited from AvaloniaObject
InitializeForContext(LayoutContext)	void	Initializes any per-container state the layout requires when it is attached to an `ILayoutable` container.
InvalidateArrange()	void	Invalidates the arrange state (layout) for all UIElement containers that reference this layout. After the invalidation, the UIElement will have its layout updated, which occurs asynchronously.
InvalidateMeasure()	void	Invalidates the measurement state (layout) for all ILayoutable containers that reference this layout.
IsAnimating(AvaloniaProperty)	bool	Checks whether a `AvaloniaProperty` is animating. Inherited from AvaloniaObject
IsSet(AvaloniaProperty)	bool	Checks whether a `AvaloniaProperty` is set on this object. Inherited from AvaloniaObject
Measure(LayoutContext, Size)	Size	Suggests a DesiredSize for a container element. A container element that supports attached layouts should call this method from their own MeasureOverride implementations to form a recursive layout update. The attached layout is expected to call the Measure for each of the container’s ILayoutable children.
SetValue(AvaloniaProperty, object, BindingPriority)	void	Sets a `AvaloniaProperty` value. Inherited from AvaloniaObject
SetValue<T>(DirectPropertyBase<T>, T)	void	Sets a `AvaloniaProperty` value. Inherited from AvaloniaObject
SetValue<T>(StyledPropertyBase<T>, T, BindingPriority)	IDisposable	Sets a `AvaloniaProperty` value. Inherited from AvaloniaObject
UninitializeForContext(LayoutContext)	void	Removes any state the layout previously stored on the ILayoutable container.
VerifyAccess()	void	Inherited from AvaloniaObject
