Hi all,      I am new to web app development. So, pardon me if I am asking a dump question:). While going through the help contents, I saw that we can build widgets and some procedure is mentioned to do it. But, I couldnt understand when I have to use it. I am from a C++ background and there you need to build before running any app. Here, I can run the app without building it. So, what do this building a widget really do? Any help will be appreciated.   Thanks.
