I have used Eclipse as a IDE (3.4.2) to develop the GWT Application using GWT(2.2.0) and GXT(2.2.4) libraries and installed GWT Designer plug-in in eclipse IDE , the designer plug-in installed successfully( attached screenshot for your reference). I have tried to open GWT Entry point class (onModuleLoad) in the designer view but its closing eclipse IDE instead of opening entry point class in the designer view. I imported GXT LayoutContainer class in GWT Entry point class. As per the product documentation GWT designer supports GXT API's
Could you please let me know if you have any documents which describes how to design pages with GXT widgets using GWT designer.
