Methods

ArrangeOverride(SizeF)

Arranges the LayoutElement to its final location. The element must call the Arrange method of each of its children.

Declaration

cs-api-definition
protected override SizeF ArrangeOverride(SizeF finalSize)

Parameters

finalSize

SizeF

The size that is available for element.

Returns

SizeF

The rectangle occupied by the element. Usually finalSize. Should you return different size, the Layout system will restart measuring and rearranging the items. That could lead to infinite recursion.

Overrides LayoutElement.ArrangeOverride(SizeF)

Remarks

In this method call to the Arrange method of each child must be made.
