示例1: hitTestLines
bool RenderFlow::hitTestLines(NodeInfo& i, int x, int y, int tx, int ty, HitTestAction hitTestAction)
{
(void) hitTestAction;
/*
if (hitTestAction != HitTestForeground) // ### port hitTest
return false;
*/
if (!firstLineBox())
return false;
// We can check the first box and last box and avoid hit testing if we don't
// contain the point. This is a quick short-circuit that we can take to avoid walking any lines.
// FIXME: This check is flawed in two extremely obscure ways.
// (1) If some line in the middle has a huge overflow, it might actually extend below the last line.
// (2) The overflow from an inline block on a line is not reported to the line.
if ((y >= ty + lastLineBox()->root()->bottomOverflow()) || (y < ty + firstLineBox()->root()->topOverflow()))
return false;
// See if our root lines contain the point. If so, then we hit test
// them further. Note that boxes can easily overlap, so we can't make any assumptions
// based off positions of our first line box or our last line box.
for (InlineFlowBox* curr = lastLineBox(); curr; curr = curr->prevFlowBox()) {
if (y >= ty + curr->root()->topOverflow() && y < ty + curr->root()->bottomOverflow()) {
bool inside = curr->nodeAtPoint(i, x, y, tx, ty);
if (inside) {

return true;
