Windows 8.1 x64上Eclipse windowbuilder pugin的java设计视图提示“未知GUI工具包”

Question

我使用的是EclipseKeplerRelease1x64，在Windows4Pro x64上使用Java7x64，我对EclipseWindowBuilder插件没有任何问题。但自从我升级到Windows 8.1 pro x64后，WindowBuilder就停止工作了

首先，下面的按钮被冻结，不响应用户的点击。

如果在ProjectExplorer中，我转到我已经用Windows7x64中的WindowBuilder插件创建的某个java文件，右键单击它并选择：openwith>；WindowBuilder编辑器，源代码可以很好地打开，但是当我切换到设计视图时，我得到了Unknown GUI toolkit。

那么，有人能告诉我如何在Windows8.1Pro x64上让WindowBuilder在Eclipse上工作吗

Answer 1

1. 转到EclipseIDE
2. 单击“项目”菜单
3. 项目属性
4. 转到java构建路径
5. 选择模块路径和添加库，然后选择1.7版本

Answer 2

您不需要重新安装整个WindowBuilder。您的工具包可能是SWT，而您的eclipse下载中可能没有SWT设计器。您只需从“安装新软件”菜单向WindowBuilder添加SWT designer功能，选择默认Luna安装站点，搜索“SWT designer”

Answer 3

我面临着同样的问题，所以我删除了整个工作区文件夹，因为我在学习的初始阶段，所以工作区中没有很多文件。然后我卸载了WindowBuilder插件，重新安装并创建了 新项目-->；包-->；WindowBuilder-->；JFrame，它对我有用

Answer 4

我通过以下方式解决了问题：

1. 卸载窗口生成器
2. 从here下载新版本窗口生成器的zip包
3. 然后我提取了它，并将其提取的目录放在eclipse的dropins文件夹中
4. 然后重新启动eclipse

WindowBuilder工作得很好

Answer 5

对我有效的是得到jfxswt。jar文件并将其添加到该项目的库中
