类型定义说明

◆ YGBaselineFunc

typedef float(* YGBaselineFunc) (YGNodeConstRef node, float width, float height)

◆ YGMeasureFunc

typedef YGSize(* YGMeasureFunc) (YGNodeConstRef node, float width, YGMeasureMode widthMode, float height, YGMeasureMode heightMode)

Returns the computed dimensions of the node, following the constraints of widthMode and heightMode:

YGMeasureModeUndefined: The parent has not imposed any constraint on the child. It can be whatever size it wants.

YGMeasureModeAtMost: The child can be as large as it wants up to the specified size.

YGMeasureModeExactly: The parent has determined an exact size for the child. The child is going to be given those bounds regardless of how big it wants to be.

返回: the size of the leaf node, measured under the given constraints.

◆ YGNodeConstRef

typedef const struct YGNode* YGNodeConstRef

Handle to an immutable Yoga Node.
