* LayoutGroup is an abstract class that provides child layout management and basic measuring and layouting.
*
- * Deriving classes should override LayoutBase::DoInitialize for second stage initialization,
+ * Deriving classes should override LayoutItem::DoInitialize for second stage initialization,
* LayoutGroup::DoRegisterChildProperties to register child property types with the owner,
* LayoutGroup::OnChildAdd to apply default child property values to the child.
* Deriving classes may override LayoutGroup::OnChildRemove.
* Deriving classes must also override OnMeasure and OnLayout as follows:
*
* OnMeasure should measure each child using LayoutGroup::MeasureChildWithMargins or LayoutGroup::MeasureChild.
- * We recommend calling LayoutBase::ResolveSizeAndState() to resolve measure specs.
+ * We recommend calling LayoutItem::ResolveSizeAndState() to resolve measure specs.
* If some children don't fit, then they can be measured again with different MeasureSpecs as required.
*
* After measurement, the derived class must also call SetMeasuredDimensions to set it's own requested size.
* OnLayout should use it's own layout parameters and the measured children's size to determine the children's
* position and size; it should then call Layout() on the child layout to layout the child and it's hierarchy.
