C++ (Cpp) YGResolveFlexDirection Examples

Example #1

File: YGNode.cpp Project: dreamevil/litho

void YGNode::setPosition(
    const YGDirection direction,
    const float mainSize,
    const float crossSize,
    const float parentWidth) {
  /* Root nodes should be always layouted as LTR, so we don't return negative
   * values. */
  const YGDirection directionRespectingRoot =
      parent_ != nullptr ? direction : YGDirectionLTR;
  const YGFlexDirection mainAxis =
      YGResolveFlexDirection(style_.flexDirection, directionRespectingRoot);
  const YGFlexDirection crossAxis =
      YGFlexDirectionCross(mainAxis, directionRespectingRoot);

  const float relativePositionMain = relativePosition(mainAxis, mainSize);
  const float relativePositionCross = relativePosition(crossAxis, crossSize);

  setLayoutPosition(
      getLeadingMargin(mainAxis, parentWidth) + relativePositionMain,
      leading[mainAxis]);
  setLayoutPosition(
      getTrailingMargin(mainAxis, parentWidth) + relativePositionMain,
      trailing[mainAxis]);
  setLayoutPosition(
      getLeadingMargin(crossAxis, parentWidth) + relativePositionCross,
      leading[crossAxis]);
  setLayoutPosition(
      getTrailingMargin(crossAxis, parentWidth) + relativePositionCross,
      trailing[crossAxis]);
}
