在以前的 Redhawk 版本中，特别是 1.8.2、1.7.5 和 1.7.2，Windows Builder Pro 包含在 Redhawk 安装中。但是，在 Redhawk 1.9.0 中，Window Builder 不是用于编辑控制面板的选项。
Redhawk 1.9.0 基于 Eclipse 3.8.1 (Luna)，所以我尝试按照http://www.eclipse.org/windowbuilder/download.php上的 Eclipse 3.8 说明自行安装 Window Builder Pro 。我能够成功安装 Window Builder，但是当我创建一个新的组件控制面板并尝试使用 Window Builder 对其进行编辑时，我收到以下错误。
WindowBuilder was not able to show the GUI. Please read the description below and look bug tracking system or discussion group for more information. Press "Create Report..." button and create a new issue if you were not able to found the similar one.
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.

Redhawk 是否在 1.9.0 版中放弃了对 Window Builder 的支持？还需要配置什么以允许 Window Builder 识别 Redhawk 控制面板？
