Protected Constructors

Layout()

Intitializes a new Xamarin.Forms.Layout instance.

Public Fields

static readonly	IsClippedToBoundsProperty	BindableProperty. Identifies the Layout.IsClippedToBounds bindable property.
static readonly	PaddingProperty	BindableProperty. Identifies the Padding bindable property.

Public Properties

	IsClippedToBounds	bool. Gets or sets a value which determines if the Layout should clip its children to its bounds.
	Padding	Thickness. Gets or sets the inner padding of the Layout.

Public Methods

	ForceLayout() Forces a layout cycle on the element and all of its descendants.
override	GetSizeRequest(double, double) : SizeRequest Returns the Xamarin.Forms.SizeRequest of the Layout. Calling this method begins the measure pass of a layout cycle.
static	LayoutChildIntoBoundingRegion(VisualElement, Rectangle) Positions a child element into a bounding region while respecting the child elements VisualElement.HorizontalOptions and VisualElement.VerticalOptions.
	LowerChild(View) Sends a child to the back of the visual stack.
	RaiseChild(View) Sends a child to the front of the visual stack.

Protected Methods

	InvalidateLayout() Invalidates the current layout.
abstract	LayoutChildren(double, double, double, double) Positions and sizes the children of a Layout.
	OnChildMeasureInvalidated() Invoked whenever a child of the layout has emitted VisualElement.MeaureInvalidated. Implement this method to add class handling for this event.
	OnChildMeasureInvalidated(object, EventArgs) Invoked whenever a child of the layout has emitted VisualElement.MeaureInvalidated. Implement this method to add class handling for this event.
override	OnSizeAllocated(double, double) This method is called when the size of the element is set during a layout cycle. This method is called directly before the VisualElement.SizeChanged event is emitted. Implement this method to add class handling for this event.
	ShouldInvalidateOnChildAdded(View) : bool When implemented, should return `true` if child should call VisualElement.InvalidateMeasure, and to return `false` if it should not.
	ShouldInvalidateOnChildRemoved(View) : bool When implemented, should return `true` if child should call VisualElement.InvalidateMeasure when it is removed, and to return `false` if it should not.
	UpdateChildrenLayout() Instructs the layout to relayout all of its children.

Public Events

LayoutChanged

Occurs at the end of a layout cycle if any of the child element's VisualElement.Bounds have changed.
