How to collapse blocks of code in Eclipse?
提问by Cristian
Some days ago my Eclipse was working fine and a +/- appeared in every block that could be collapsed (functions, classes, etc.)... but now it does appear, and I don't know how to activate that feature again.
几天前，我的 Eclipse 工作正常，并且 +/- 出现在每个可以折叠的块（函数、类等）中……但现在它确实出现了，我不知道如何再次激活该功能.
It's Eclipse Helios, running on a Gentoo Linux box.

Preferences -> C++ -> Editor -> Folding ?
首选项 -> C++ -> 编辑器 -> 折叠 ?
Make a right click in the editor window and go to preferences there, then only the editor-relevant section of the preferences dialog will appear. This works for JDT, CDT etc...
在编辑器窗口中右键单击并转到那里的首选项，然后只会出现首选项对话框中与编辑器相关的部分。这适用于 JDT、CDT 等...

You can do ( Ctrl+ Numpad_Divide) to enable folding.
Also if you Right Clickon the area where the +or -was supposed to be, you can see there is a folding option.
您可以执行 ( Ctrl+ Numpad_Divide) 以启用折叠。
此外，如果您Right Click在+或-应该在的区域，您可以看到有一个折叠选项。

Try this option: Preferences > Java > Editor > Folding > Enable folding
试试这个选项：首选项 > Java > 编辑器 > 折叠 > 启用折叠

For Python it is as follows:
对于 Python，它如下所示：
- collapse all 1 level: Ctrl+9
- expand all 1 level: Ctrl+0
- collapse current: Ctrl+-
- expand current: Ctrl++
- 折叠所有 1 个级别：Ctrl+9
- 展开所有 1 个级别：Ctrl+0
- 崩溃电流：Ctrl+-
- 展开电流：Ctrl++
Hope that helps.
希望有帮助。

In Preferences, you'll find General > Keys. It's for setting your keyboard shortcuts.
在“首选项”中，您会找到“常规”>“键”。它用于设置键盘快捷键。
What I use it for more often, though, is to find stuff in Eclipse. You should see an input box labelled "type filter text." It's as close as Eclipse comes to a search feature for every Eclipse command.
不过，我更经常使用它的目的是在 Eclipse 中查找内容。您应该会看到一个标有“类型过滤器文本”的输入框。它就像 Eclipse 为每个 Eclipse 命令提供搜索功能一样。

I assume you are using Java, but look under the settings for your particular language.
我假设您使用的是 Java，但请查看您的特定语言的设置。
Under the Window menu, select Preferences.
在窗口菜单下，选择首选项。
Under Java->Editor->Folding. Select "Enable Folding".
在 Java->Editor->Folding 下。选择“启用折叠”。

In CFEclipse: Preferences > CFEclipse > Editor > Code Folding > Initially Collapse column, you can uncheck to see all expanded when opening, or check all boxes to close all when opening a file.
在 CFEclipse 中：首选项 > CFEclipse > 编辑器 > 代码折叠 > 初始折叠列，您可以取消选中以在打开时查看所有展开，或选中所有框以在打开文件时全部关闭。

I was using salesforce apex classes with Eclipse Neon 3.3 for Java.
I found an option "define folding region" on right click in the editor, I selected the block of code i wanted to collapse and selected this property for that code. Now I am seeing + and - symbol to expand and collapse that block of code
我在 Eclipse Neon 3.3 for Java 中使用了 salesforce apex 类。
我在编辑器中右键单击找到了一个选项“定义折叠区域”，我选择了我想要折叠的代码块并为该代码选择了这个属性。现在我看到 + 和 - 符号来展开和折叠该代码块
