list里面还没有内容，是不是list的背景色也看不见?

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);

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
