函数说明

YGConfigFree()

void YGConfigFree

(

YGConfigRef

config

)

Frees the associated Yoga configuration.

函数调用图:

YGConfigGetContext()

void * YGConfigGetContext

(

YGConfigConstRef

config

)

Gets the currently set context.

YGConfigGetDefault()

YGConfigConstRef YGConfigGetDefault

(

void

)

Returns the default config values set by Yoga.

这是这个函数的调用关系图:

YGConfigGetErrata()

YGErrata YGConfigGetErrata

(

YGConfigConstRef

config

)

Get the currently set errata.

函数调用图:

这是这个函数的调用关系图:

YGConfigGetPointScaleFactor()

float YGConfigGetPointScaleFactor

(

YGConfigConstRef

config

)

Get the currently set point scale factor.

函数调用图:

这是这个函数的调用关系图:

YGConfigGetUseWebDefaults()

bool YGConfigGetUseWebDefaults

(

YGConfigConstRef

config

)

Whether the configuration is set to use web defaults.

函数调用图:

这是这个函数的调用关系图:

YGConfigIsExperimentalFeatureEnabled()

bool YGConfigIsExperimentalFeatureEnabled	(	YGConfigConstRef	config,
		YGExperimentalFeature	feature )

Whether an experimental feature is set.

函数调用图:

这是这个函数的调用关系图:

YGConfigNew()

YGConfigRef YGConfigNew

(

void

)

Allocates a set of configuration options. The configuration may be applied to multiple nodes (i.e. a single global config), or can be applied more granularly per-node.

函数调用图:

YGConfigSetCloneNodeFunc()

void YGConfigSetCloneNodeFunc	(	YGConfigRef	config,
		YGCloneNodeFunc	callback )

Sets a callback, called during layout, to create a new mutable Yoga node if Yoga must write to it and its owner is not its parent observed during layout.

函数调用图:

这是这个函数的调用关系图:

YGConfigSetContext()

void YGConfigSetContext	(	YGConfigRef	config,
		void *	context )

Sets an arbitrary context pointer on the config which may be read from during callbacks.

函数调用图:

这是这个函数的调用关系图:

YGConfigSetErrata()

void YGConfigSetErrata	(	YGConfigRef	config,
		YGErrata	errata )

Configures how Yoga balances W3C conformance vs compatibility with layouts created against earlier versions of Yoga.

By default Yoga will prioritize W3C conformance. Errata may be set to ask Yoga to produce specific incorrect behaviors. E.g. YGConfigSetErrata(config, YGErrataStretchFlexBasis).

YGErrata is a bitmask, and multiple errata may be set at once. Predefined constants exist for convenience:

1. YGErrataNone: No errata
2. YGErrataClassic: Match layout behaviors of Yoga 1.x
3. YGErrataAll: Match layout behaviors of Yoga 1.x, including UseLegacyStretchBehaviour

函数调用图:

这是这个函数的调用关系图:

YGConfigSetExperimentalFeatureEnabled()

void YGConfigSetExperimentalFeatureEnabled	(	YGConfigRef	config,
		YGExperimentalFeature	feature,
		bool	enabled )

Enable an experimental/unsupported feature in Yoga.

函数调用图:

这是这个函数的调用关系图:

YGConfigSetLogger()

void YGConfigSetLogger	(	YGConfigRef	config,
		YGLogger	logger )

Set a custom log function for to use when logging diagnostics or fatal. errors.

函数调用图:

这是这个函数的调用关系图:

YGConfigSetPointScaleFactor()

void YGConfigSetPointScaleFactor	(	YGConfigRef	config,
		float	pixelsInPoint )

Yoga will by default round final layout positions and dimensions to the nearst point. pointScaleFactor controls the density of the grid used for layout rounding (e.g. to round to the closest display pixel).

May be set to 0.0f to avoid rounding the layout results.

函数调用图:

这是这个函数的调用关系图:

YGConfigSetUseWebDefaults()

void YGConfigSetUseWebDefaults	(	YGConfigRef	config,
		bool	enabled )

Yoga by default creates new nodes with style defaults different from flexbox on web (e.g. YGFlexDirectionColumn and YGPositionRelative). UseWebDefaults instructs Yoga to instead use a default style consistent with the web.
