Summary

At this point, we have made the basics of our application, one which doesn't do much right now but that is ready to be extended further as we continue to add new geospatial functionality. You learned to create a solid toolkit foundation of tools and widgets that we can use to build our GUI in a separate and flexible builder module, some of which will be extended in later chapters. The main missing piece, before we can say we have a functional GIS application, is to visualize data in our map widget. This is what we turn to in the next chapter.
