C++ (Cpp) scrollBehaviorStyle Beispiele

Beispiel #1

void RootFrameViewport::setScrollOffset(const ScrollOffset& offset,
                                        ScrollType scrollType,
                                        ScrollBehavior scrollBehavior) {
  updateScrollAnimator();

  if (scrollBehavior == ScrollBehaviorAuto)
    scrollBehavior = scrollBehaviorStyle();

  if (scrollType == ProgrammaticScroll &&
      !layoutViewport().isProgrammaticallyScrollable())
    return;

  if (scrollType == AnchoringScroll) {
    distributeScrollBetweenViewports(offset, scrollType, scrollBehavior,
                                     LayoutViewport);
    return;
  }

  if (scrollBehavior == ScrollBehaviorSmooth) {
    distributeScrollBetweenViewports(offset, scrollType, scrollBehavior,
                                     VisualViewport);
    return;
  }

  ScrollOffset clampedOffset = clampScrollOffset(offset);
  ScrollableArea::setScrollOffset(clampedOffset, scrollType, scrollBehavior);
}
