I have developed ARCGIS QT Widget application with some basic functionality...Can I integrate it with existing UI application?
How to do that?
To use the Runtime SDK in an existing app, all you should need to do is include the provided PRI file as specified here - Qt SDK best practices—ArcGIS Runtime SDK for Qt | ArcGIS for Developers. Once you run qmake again, you should now have access to all of the ArcGIS headers and everything you need to start coding in your app.
ok thanks
