list里面还没有内容，是不是list的背景色也看不见?

自己顶

我也不会用，帮你顶吧
[解决办法]
IDECORATOR_SetWidget((IDecorator*)pMe->m_pScrollWidget, pMe->m_pListWidget);

这里应该有问题，应该加一句
pMe->m_pListWidget = pMe->m_pScrollWidget;  你看一下装饰工厂

    wp.x = 10;
    wp.y = 10;
    wp.bVisible = TRUE;
    result = IXYCONTAINER_Insert(pMe->m_pXYContainer, pMe->m_pListWidget, WIDGET_ZNORMAL, &wp);

[解决办法]
你有设置listwidget和scrollbar的extent吗？还有，插入到container的时候，应该是插pMe->m_pScrollWidget才对
