Question

当我尝试通过视口向上或向下滚动滚动条中的内容时，我遇到了问题。

我的MXML鳕鱼是

 <s:BorderContainer width="100%" cornerRadius="3" backgroundColor="#999AAA" 
                       borderAlpha="0" borderColor="#999AAA" backgroundAlpha="0">
        <s:layout>
            <s:VerticalLayout paddingTop="0" horizontalAlign="left" />
        </s:layout>

        <s:Scroller id="id_Scroller" width="100%" height="100%" verticalScrollPolicy="off" horizontalScrollPolicy="off" >
            <s:Group width="100%" height="100%" >
                <s:layout>
                    <s:VerticalLayout paddingTop="2" horizontalAlign="center" gap="1" clipAndEnableScrolling="true"/>
                </s:layout>

                <vitals:VBVitalsGridPanel id="id_VBVitalsGridPanel" width="100%" ExpandedView="true"  allowSlideOut="true"
                                          QSSlideStateChange="slideoutManager.QSAutoSlideChangeHandler(event)"
                                          QSViewStateChange="slideoutManager.QSAutoCollapseHandler(event)"
                                          />
                <cc:VBCCHPIGridPanle width="100%" ExpandedView="false" id="id_hpi" allowSlideOut="true"
                                     QSSlideStateChange="slideoutManager.QSAutoSlideChangeHandler(event)"
                                     QSViewStateChange="slideoutManager.QSAutoCollapseHandler(event)"
                                     />
                <ros:VBROSGridPanel width="100%" ExpandedView="false" id="id_ros" allowSlideOut="true"
                                    QSSlideStateChange="slideoutManager.QSAutoSlideChangeHandler(event)"
                                    QSViewStateChange="slideoutManager.QSAutoCollapseHandler(event)"
                                    />
                <physical:VBPhysicalGridView width="100%" ExpandedView="false" id="id_physical" allowSlideOut="true"
                                             QSSlideStateChange="slideoutManager.QSAutoSlideChangeHandler(event)"
                                             QSViewStateChange="slideoutManager.QSAutoCollapseHandler(event)"
                                             />

                <lab:VBLabViewPanel width="100%" ExpandedView="false" id="id_lab" allowSlideOut="true"
                                    QSSlideStateChange="slideoutManager.QSAutoSlideChangeHandler(event)"
                                    QSViewStateChange="slideoutManager.QSAutoCollapseHandler(event)"
                                    />
            </s:Group>
        </s:Scroller>
    </s:BorderContainer>

我的滚动功能就在这里，

public function ScrollUp():void
        {
            id_Scroller.viewport.verticalScrollPosition +=  15;
            trace(' -->> '+ id_Scroller.viewport.verticalScrollPosition)
        }

        public function ScrollDown():void
        {
            id_Scroller.viewport.verticalScrollPosition -= 15;
        }

当我向上滚动时，我总是15岁。

为什么？

请帮助我THNAKS

Answer 1

尝试移除高度和高度来自小组的宽度

<s:Group width="100%" height="100%" >
//-->
<s:Group>

你还需要

<s:Group clipAndEnableScrolling="true" >

尝试这样做：

scroller.verticalScrollBar.value += 15;

Flex Spark视口滚动问题？
