cocos2dx3.10 带滚动条的ScrollView和TableView

scroview有2个虚方法：

virtual void scrollViewDidScroll(ScrollView* view)：这是当scrollView在被拖动时会响应该函数；

virtual void scrollViewDidZoom(ScrollView* view)：这是当scrollView在进行缩放时会响应该函数;

self._ScrollView = self:getWidget("ScrollView_1")   -- self._ScrollView:setInertiaScrollEnabled(false)   self._slider = self:getWidget("Slider_1")    local function percentChangedEvent(sender,eventType)        print(eventType)        if eventType == ccui.SliderEventType.percentChanged then            local slider = sender            local percent = slider:getPercent()            self._ScrollView:jumpToPercentVertical(percent)        elseif eventType == ccui.SliderEventType.slideBallUp then            -- self._displayValueLabel:setString("Slide Ball Up")        elseif eventType == ccui.SliderEventType.slideBallDown then            -- self._displayValueLabel:setString("Slide Ball Down")        elseif eventType == ccui.SliderEventType.slideBallCancel then            -- self._displayValueLabel:setString("Slide Ball Cancel")        end    end--[[    typedef enum{    --typedef:  0--8    SCROLLVIEW_EVENT_SCROLL_TO_TOP,         SCROLLVIEW_EVENT_SCROLL_TO_BOTTOM,    SCROLLVIEW_EVENT_SCROLL_TO_LEFT,    SCROLLVIEW_EVENT_SCROLL_TO_RIGHT,    SCROLLVIEW_EVENT_SCROLLING,    SCROLLVIEW_EVENT_BOUNCE_TOP,    SCROLLVIEW_EVENT_BOUNCE_BOTTOM,    SCROLLVIEW_EVENT_BOUNCE_LEFT,    SCROLLVIEW_EVENT_BOUNCE_RIGHT}ScrollviewEventType;]]      local function scrollViewDidScroll(view)        local pos = view:getInnerContainerPosition()        local posy = math.abs(pos.y)        local InnerSize = view:getInnerContainerSize()        local ScrollViewSize = view:getContentSize()        local scroTotalHeight = InnerSize.height - ScrollViewSize.height        local percent = (posy/scroTotalHeight)*100        self._slider:setPercent(100-percent)    end    --[[    local function ScrollCallback(sender,eventType)        if eventType == SCROLLVIEW_EVENT_SCROLLING then            -- print("---scrolling-----")            local pos = self._ScrollView:getInnerContainerPosition()            -- print("---pos-----", pos.x, pos.y)            local posy = math.abs(pos.y)            local InnerSize = self._ScrollView:getInnerContainerSize()            local ScrollViewSize = self._ScrollView:getContentSize()            local scroTotalHeight = InnerSize.height - ScrollViewSize.height            -- print("---InnerSize--ScrollViewSize-",InnerSize.width, InnerSize.height, ScrollViewSize.width, ScrollViewSize.height)            local percent = (posy/scroTotalHeight)*100            self._slider:setPercent(100-percent)        elseif eventType == SCROLLVIEW_EVENT_SCROLL_TO_TOP then            -- print("---scroll to top-----")        elseif eventType == SCROLLVIEW_EVENT_SCROLL_TO_BOTTOM then            -- print("---scroll to bottom-----")        end    end    --]]    self._slider:addEventListener(percentChangedEvent)    self._ScrollView:addEventListener(scrollViewDidScroll)

TableView：
