The parser parsed the compilation unit, but can't identify any GUI toolkit.
Possible reasons:
You open a compilation unit without any GUI, such as an empty class, data bean, etc.
Classpath of project is not valid, does not include all required toolkit libraries.
You attempt to open UI for toolkit, support for which is not installed in WindowBuilder.
Use button Show UI Toolkits to install new toolkit.
