函数说明

◆ YGNodeCalculateLayout()

void YGNodeCalculateLayout	(	YGNodeRef	node,
		float	availableWidth,
		float	availableHeight,
		YGDirection	ownerDirection )

Calculates the layout of the tree rooted at the given node.

Layout results may be read after calling YGNodeCalculateLayout() using functions like YGNodeLayoutGetLeft(), YGNodeLayoutGetTop(), etc.

YGNodeGetHasNewLayout() may be read to know if the layout of the node or its subtrees may have changed since the last time YGNodeCalculate() was called.
