示例1: addRegion
void TextTrack::addRegion(PassRefPtr<VTTRegion> prpRegion)
{
if (!prpRegion)
return;
RefPtr<VTTRegion> region = prpRegion;
VTTRegionList* regionList = ensureVTTRegionList();
// 1. If the given region is in a text track list of regions, then remove
// region from that text track list of regions.
TextTrack* regionTrack = region->track();
if (regionTrack && regionTrack != this)
regionTrack->removeRegion(region.get(), ASSERT_NO_EXCEPTION);
// 2. If the method's TextTrack object's text track list of regions contains
// a region with the same identifier as region replace the values of that
// region's width, height, anchor point, viewport anchor point and scroll
// attributes with those of region.
VTTRegion* existingRegion = regionList->getRegionById(region->id());
if (existingRegion) {
existingRegion->updateParametersFromRegion(region.get());
return;
}
// Otherwise: add region to the method's TextTrack object's text track
// list of regions.
region->setTrack(this);
regionList->add(region);
