Does GWT Designer support GWT-EXT or MyGWT?
GWT Designer has some limited support for gwt-ext. All standard GWT widgets work with GWT Designer as do any widgets that are JavaBean compliant (e.g., they include a public default constructor and expose properties via getter/setter pairs). Widgets that define their own API and don’t conform to the JavaBean spec likely will not work as-is (which is the case with most of the gwt-ext and MyGWT widgets). You can wrapper the gwt-ext or MyGWT widgets in a Composite subclass in order to see them in GWT Designer (see the ImageViewer example in this project which shows a TabPanel within a Composite). We do plan to eventually provide full support for the gwt-ext widgets, but it won’t happen right away. GWT itself has only just come out of beta, and the gwt-ext and MyGWT widgets are still very much in their early stages. Until those widgets have been finalized and their API stablized, any support we added for them would be premature and likely a waste of our engineering resources.
