B.9. Chapter 14 Exercise

This exercise asked you to create an application that reads the folder or file properties from the selected row of both the FileSystemDataGrid and FileSystemList components. The solution file is shown in Listing B-16. This file has two functions that operate in the same way. Each will cast the selectedItem from either the FileSystemDataGrid or FileSystemList as a File and then write name and size properties to one of the TextArea components. The results of this can be seen in Figure B-12.
