示例1: flowThreadTranslationAtOffset
LayoutSize MultiColumnFragmentainerGroup::flowThreadTranslationAtOffset(LayoutUnit offsetInFlowThread) const
{
LayoutMultiColumnFlowThread* flowThread = m_columnSet.multiColumnFlowThread();
unsigned columnIndex = columnIndexAtOffset(offsetInFlowThread);
LayoutRect portionRect(flowThreadPortionRectAt(columnIndex));
flowThread->flipForWritingMode(portionRect);
LayoutRect columnRect(columnRectAt(columnIndex));
m_columnSet.flipForWritingMode(columnRect);
LayoutSize translationRelativeToGroup = columnRect.location() - portionRect.location();
LayoutSize enclosingTranslation;
if (LayoutMultiColumnFlowThread* enclosingFlowThread = flowThread->enclosingFlowThread()) {
// Translation that would map points in the coordinate space of the outermost flow thread to
// visual points in the first column in the first fragmentainer group (row) in our multicol
// container.
LayoutSize enclosingTranslationOrigin = enclosingFlowThread->flowThreadTranslationAtOffset(flowThread->blockOffsetInEnclosingFlowThread());
// Translation that would map points in the coordinate space of the outermost flow thread to
// visual points in the first column in this fragmentainer group.
enclosingTranslation = enclosingFlowThread->flowThreadTranslationAtOffset(blockOffsetInEnclosingFlowThread());
// What we ultimately return from this method is a translation that maps points in the
// coordinate space of our flow thread to a visual point in a certain column in this
// fragmentainer group. We had to go all the way up to the outermost flow thread, since this
// fragmentainer group may be in a different outer column than the first outer column that
// this multicol container lives in. It's the visual distance between the first
// fragmentainer group and this fragmentainer group that we need to add to the translation.
enclosingTranslation -= enclosingTranslationOrigin;
}
return enclosingTranslation + translationRelativeToGroup + offsetFromColumnSet() + m_columnSet.topLeftLocationOffset() - flowThread->topLeftLocationOffset();
