Usando WindowBuilder

Assuntos Gerais
#1

Bom, utilizava o JAVA com Visual Editor a alguns meses atras, agora voltei ao java e li que mudou para o WIndowBuilder, já instalei tudo e quando tento abrir minha classe java (que tem janelas) da o erro abaixo :

Unknown GUI toolkit
The parser parsed the compilation unit, but can't identify any GUI toolkit, so WindowBuilder can't display any GUI to edit. This can be caused by one of the following reasons: 

This class is not an editable UI class and contains no UI components. 
WindowBuilder does not recognize the GUI toolkit or library used in this class. 
WindowBuilder does not understand this GUI type/pattern in a supported GUI toolkit. 
Problems exist with the classpath. For example, the compilation unit uses SWT classes, but the SWT/JFace libraries are not included into the classpath.

#2

Olha a mensagem de erro ta dando diversas dicas do que pode ser o erro:

This class is not an editable UI class and contains no UI components.
A classe não é uma classe de Interface com Usuário (UI) editável e não contém componentes de UI

WindowBuilder does not recognize the GUI toolkit or library used in this class.
O WB não reconhece o toolkit GUI ou biblioteca usada na classe

WindowBuilder does not understand this GUI type/pattern in a supported GUI toolkit.
WindowBuilder não entende essa GUI pois o tipo/padrão da GUI toolkit não é suportado

Problems exist with the classpath. For example, the compilation unit uses SWT classes, but the SWT/JFace libraries are not included into the classpath.
Existem problemas com o classpath. Por exemplo, a unidade de compilação usa classes SWT, mas as bibliotecas SWT / JFace não estão incluídos no classpath.

#3

Mais veja, mesmo se eu tentar criar uma classe SWT User Interface da este erro :

Cannot complete the install because of a conflicting dependency. Software being installed: SWT Designer 1.1.0.r37x201107161502 (org.eclipse.wb.rcp.feature.feature.group 1.1.0.r37x201107161502) Software currently installed: WindowBuilder Core UI 1.0.0.r37x201106081733 (org.eclipse.wb.core.ui.feature.feature.group 1.0.0.r37x201106081733) Only one of the following can be installed at once: WindowBuilder Discovery Core 1.1.0.r37x201107161227 (org.eclipse.wb.discovery.core 1.1.0.r37x201107161227) org.eclipse.wb.discovery.core 1.0.0.r37x201106081733 Cannot satisfy dependency: From: WindowBuilder Core UI 1.0.0.r37x201106081733 (org.eclipse.wb.core.ui.feature.feature.group 1.0.0.r37x201106081733) To: org.eclipse.wb.discovery.core [1.0.0.r37x201106081733] Cannot satisfy dependency: From: WindowBuilder Core UI 1.1.0.r37x201107161227 (org.eclipse.wb.core.ui.feature.feature.group 1.1.0.r37x201107161227) To: org.eclipse.wb.discovery.core [1.1.0.r37x201107161227] Cannot satisfy dependency: From: SWT Designer 1.1.0.r37x201107161502 (org.eclipse.wb.rcp.feature.feature.group 1.1.0.r37x201107161502) To: org.eclipse.wb.core.ui.feature.feature.group 1.1.0.r37x201107161227

Parace-me que tem algo errado no meu WindowBuilder ! (Estou voltando agora para o java, por isso nunca manipulei o WindowBuilder) apenas o Visual Editor
