QT is used for the cross-plarform UI purposes. So if you are intereseted only in those part of code which are using Visualize SDK - yes you can investigate OdVisualizeViewer code. But certainly you will not able to build and debug it. Also we have a simplified Windows sample OdVisualizeFirstApp without Qt. It can be used for the first familiarity with Visualize SDK.
