GWT to GXT migration
These days, I am discovering GWT, and more accurately ExtGWT, aka GXT.
Case
I have to write a “Hello World” application based on GXT.
Steps
- Firstly, follow Lars Vogel’s tutorial to have a “Hello World” in GWT.
- In Eclipse, add a dependancy from your project to
extjs-gxt-lib-2.1.1.jar(version compatible with your GWT version: 1.7 or 2.0), available at this link. - In your
*.gwt.xmlfile, remove:
[xml]<inherits name=’com.google.gwt.user.theme.standard.Standard’/>[/xml]and add:
[xml]<inherits name=’com.extjs.gxt.ui.GXT’/>[/xml]
- Get the gxt-all.css file, copy it into
war/css/folder - In your
*.htmlfile, add the lines:
[xml]<link rel="stylesheet" type="text/css" href="css/gxt-all.css" />[/xml] - Now, adapt your Java entry point source class, replacing GWT widgets with GXT ones.
- Restart your server and refresh the page in your browser. You have your “Hello World” in GXT!
