I can't find any method for making a tab invisible or otherwise hidden in an SWT/JFace application --- I want a second tab to be available (or not) based on some other preferences set by the user.
在SWT/JFace应用程序中，我找不到任何使选项卡隐形或以其他方式隐藏的方法——我希望第二个选项卡基于用户设置的其他一些首选项可用(或不可用)。
It shouldn't be so hard to figure this out!
要弄明白这一点应该不难!

The only way that I know of is to dispose the CTabItem for the tab you want to hide and then create a new CTabItem when you want to show it. Sort of,
我所知道的惟一方法是为要隐藏的选项卡配置CTabItem，然后在想要显示它时创建一个新的CTabItem。的,
CTabFolder folder = new CTabFolder(parent, SWT.NONE);
Label label = new Label(folder, SWT.NONE);
label.setText("Hello");
CTabItem item = new CTabItem(folder);
item.setControl(label);
// Hide it
item.dipose();
// show it again
CTabItem item = new CTabItem(folder);
item.setControl(label);
If you want to hide a tab in the middle you'll need to recreate all the tabs after the one you disposed.. It's probably easiest if you create a class that holds the control and a field that can be used to toggle the visibility. Then you can just dipose all the CTabItems and recreate iff the visibility field is true.
如果你想在中间隐藏一个标签，你需要重新创建所有的标签后，你处置。如果您创建了一个包含控件的类和一个可以用来切换可见性的字段，这可能是最简单的。然后您可以分解所有CTabItems并重新创建iff可见性字段为true。
