Summary
In this chapter, we learned how to export the content of a GridPanel to PDF, Excel, and also a page that is printer-friendly.
We have also learned how to create different types of charts, use only one component and change its active item, and export a chart to an image or PDF using Ext JS native features.
In the next chapter, we will learn how to test the application, how to enable touch support (so that we can execute the application from a tablet or smartphone), and also how to enable routing.
