类型定义说明
◆ YGCloneNodeFunc
| typedef YGNodeRef(* YGCloneNodeFunc) (YGNodeConstRef oldNode, YGNodeConstRef owner, size_t childIndex) |
Function pointer type for YGConfigSetCloneNodeFunc.
◆ YGConfigConstRef
| typedef const struct YGConfig* YGConfigConstRef |
Handle to an immutable Yoga configuration.
◆ YGConfigRef
| typedef struct YGConfig* YGConfigRef |
Handle to a mutable Yoga configuration.
◆ YGLogger
| typedef int(* YGLogger) (YGConfigConstRef config, YGNodeConstRef node, YGLogLevel level, const char *format, va_list args) |
Function pointer type for YGConfigSetLogger.
◆ YGNodeConstRef
| typedef const struct YGNode* YGNodeConstRef |
◆ YGNodeRef
函数说明
◆ YGConfigFree()
| YG_EXPORT void YGConfigFree | ( | YGConfigRef | config | ) |
Frees the associated Yoga configuration.
◆ YGConfigGetContext()
| YG_EXPORT void * YGConfigGetContext | ( | YGConfigConstRef | config | ) |
Gets the currently set context.
◆ YGConfigGetDefault()
| YG_EXPORT YGConfigConstRef YGConfigGetDefault | ( | void | ) |
Returns the default config values set by Yoga.
◆ YGConfigGetErrata()
| YG_EXPORT YGErrata YGConfigGetErrata | ( | YGConfigConstRef | config | ) |
Get the currently set errata.
◆ YGConfigGetPointScaleFactor()
| YG_EXPORT float YGConfigGetPointScaleFactor | ( | YGConfigConstRef | config | ) |
Get the currently set point scale factor.
◆ YGConfigGetUseWebDefaults()
| YG_EXPORT bool YGConfigGetUseWebDefaults | ( | YGConfigConstRef | config | ) |
Whether the configuration is set to use web defaults.
◆ YGConfigIsExperimentalFeatureEnabled()
| YG_EXPORT bool YGConfigIsExperimentalFeatureEnabled | ( | YGConfigConstRef | config, |
| YGExperimentalFeature | feature ) |
Whether an experimental feature is set.
◆ YGConfigNew()
| YG_EXPORT 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.
◆ YGConfigSetCloneNodeFunc()
| YG_EXPORT 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.
◆ YGConfigSetContext()
| YG_EXPORT void YGConfigSetContext | ( | YGConfigRef | config, |
| void * | context ) |
Sets an arbitrary context pointer on the config which may be read from during callbacks.
◆ YGConfigSetErrata()
| YG_EXPORT 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:
- YGErrataNone: No errata
- YGErrataClassic: Match layout behaviors of Yoga 1.x
- YGErrataAll: Match layout behaviors of Yoga 1.x, including
UseLegacyStretchBehaviour
◆ YGConfigSetExperimentalFeatureEnabled()
| YG_EXPORT void YGConfigSetExperimentalFeatureEnabled | ( | YGConfigRef | config, |
| YGExperimentalFeature | feature, | ||
| bool | enabled ) |
Enable an experimental/unsupported feature in Yoga.
◆ YGConfigSetLogger()
| YG_EXPORT void YGConfigSetLogger | ( | YGConfigRef | config, |
| YGLogger | logger ) |
Set a custom log function for to use when logging diagnostics or fatal. errors.
◆ YGConfigSetPointScaleFactor()
| YG_EXPORT 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.
◆ YGConfigSetUseWebDefaults()
| YG_EXPORT 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.
