Qt support for QScrollArea Class

See the link I supplied in your other thread (https://community.smartbear.com/t5/TestComplete-Desktop-Testing/Qt-widget-inside-Qscrollarea/m-p/165605).  That documents all the supported components.  If QScrollArea isn't listed, then you don't have full access to all methods and properties directly.  You can work around it by perhaps mapping it to a different component using object mapping.
