Here is my code, but I only see the grey scrollview that cant be scrolled and I dont see my buttons. Any help?

Header files: “cocos-ext.h” “CocosGUI”

Size scollFrameSize = Size(visibleSize.width, visibleSize.height/4);
auto scrollView = cocos2d::ui::ScrollView::create();
scrollView->setContentSize(scollFrameSize);
scrollView->setBackGroundColorType(cocos2d::ui::Layout::BackGroundColorType::SOLID);
scrollView->setBackGroundColor(Color3B(200, 200, 200));
scrollView->setPosition(Point(0, visibleSize.height/1.5));
scrollView->setDirection(cocos2d::ui::ScrollView::Direction::HORIZONTAL);
scrollView->setBounceEnabled(true);
scrollView->setTouchEnabled(true);
auto containerSize = Size(scollFrameSize.width*2, scollFrameSize.height*2);
scrollView->setInnerContainerSize(containerSize);

this->addChild(scrollView);


auto button1 = cocos2d::ui::Button::create();
button1->setColor(Color3B(250, 200, 50));
button1->setTouchEnabled(true);
button1->setContentSize(Size(100, 100));
button1->setPosition(Point(containerSize.width / 4, containerSize.height / 2));
scrollView->addChild(button1);

auto button2 = cocos2d::ui::Button::create();
button2->setColor(Color3B(250, 200, 50));
button1->setContentSize(Size(100, 100));
button2->setTouchEnabled(true);
button2->setPosition(Point(containerSize.width / 8, containerSize.height / 2));
scrollView->addChild(button2);

I figured it out for anyone who is interested. Add a button like this:

auto button1 = ui::Button::create();
button1->setTouchEnabled(true);
button1->ignoreContentAdaptWithSize(false);
button1->setContentSize(Size(100, 100));
button1->loadTextures("pic1.png", "pic2.png");
button1->setPosition(Point(containerSize.width / 8, containerSize.height / 2));
scrollView->addChild(button1);
