当来自 Eclipse 的 运行 时，SWT CTabFolder 不显示
SWT CTabFolder doesn't display when running from eclipse
我正在使用 Eclipse 4.4.2 中的 WindowBuilder 创建一个应用程序。我添加了 CTabFolders 和相应的 CTabItems。在 windowbuilder.
中单击预览按钮（无需编译或 运行 快速 test/preview 或 运行 即可正确显示选项卡。

任何人都可以提出解决方案。提前致谢。
最后我找到了代码中的问题。基本布局中的组合按如下方式分配了 StackLayout。
Composite content = new Composite(shell, SWT.BORDER);
content.setLayout(new StackLayout());
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
当我将 StackLayout 更改为 GridLayout 时，我得到了一个可行的解决方案。
Composite content = new Composite(shell, SWT.BORDER);
content.setLayout(new GridLayout(1, false));
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
我正在使用 Eclipse 4.4.2 中的 WindowBuilder 创建一个应用程序。我添加了 CTabFolders 和相应的 CTabItems。在 windowbuilder.
中单击预览按钮（无需编译或 运行 快速 test/preview 或 运行 即可正确显示选项卡。屏幕截图===> http://i.imgur.com/Sx9TQrL.jpg

任何人都可以提出解决方案。提前致谢。
最后我找到了代码中的问题。基本布局中的组合按如下方式分配了 StackLayout。
Composite content = new Composite(shell, SWT.BORDER);
content.setLayout(new StackLayout());
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
当我将 StackLayout 更改为 GridLayout 时，我得到了一个可行的解决方案。
Composite content = new Composite(shell, SWT.BORDER);
content.setLayout(new GridLayout(1, false));
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
