OnLayout(bool, LayoutLength, LayoutLength, LayoutLength, LayoutLength)

Called from Layout() when this layout should assign a size and position to each of its children.
Derived classes with children should override this method and call Layout() on each of their children.

Declaration

Parameters

Type	Name	Description
bool	changed	This is a new size or position for this layout.
LayoutLength	left	Left position, relative to parent.

Overrides

LayoutGroup.OnLayout(bool, LayoutLength, LayoutLength, LayoutLength, LayoutLength)

OnMeasure(MeasureSpecification, MeasureSpecification)

Measure the layout and its content to determine the measured width and the measured height.
