A wrapper means that it is not written in Java. It is javascript code, with just a calling Java wrapper around it so that it can be used from GWT. By not being written in Java you don't get the advantages the GWT compiler offers. Some of those I listed. First was code elimination. GWT compiler can tell what code is never referenced (in the Java written code, not javascript) and eliminate the code so you don't ever download code that is not being used. And download time is a big problem in web apps. You don't want an app that takes a long time to show display. Another thing the GWT compiler does is compile different versions of the code for different browsers using the javascript that is tailored to that browser (it will also do this for different (human) languages you want to display your app in). The another big advantage of the GWT compiler is code splitting. You can tell the compiler where to break up the code so that code that is not needed initially can be downloaded when needed and doesn't take up bandwidth when it first loads.
I hope that helps :) On Jan 12, 6:56 am, Stine Søndergaard <stinespl...@gmail.com> wrote: > Hello again :) It would be fantastic if you could maybe attach a few more > words to this: > > "SmartGWT is a javascript wrapper - which > means you don't get the advantages of the compiler, browser specific > code compiles, code elimination, and runAsync (code splitting)." > > ...
