C++ (Cpp) RenderBlockFlow::logicalHeight示例

static void updateLineConstrains(const RenderBlockFlow& flow, LineState& line, bool isFirstLine)
{
    bool shouldApplyTextIndent = !flow.isAnonymous() || flow.parent()->firstChild() == &flow;
    LayoutUnit height = flow.logicalHeight();

    float logicalRightOffset = flow.logicalRightOffsetForLine(height, false, logicalHeight);
    line.setLogicalLeftOffset(flow.logicalLeftOffsetForLine(height, false, logicalHeight) + (shouldApplyTextIndent && isFirstLine ? flow.textIndentOffset() : LayoutUnit(0)));
    line.setAvailableWidth(std::max<float>(0, logicalRightOffset - line.logicalLeftOffset()));
