Ctrl + Space does not work to support content on eclipse

Question

My problem is that the content support window will not appear after pressing Ctrl + Space . I checked my shortcuts and the content support is tied to Ctrl + Space . Sometimes a window automatically pops up, making a suggestion after entering a point, for example, but this will not happen when using a key combination.

Eclipse Version:

Eclipse Java EE IDE for web developers.

Version: Kepler Service Release 1 Build id: 20130919-0819

My OS is Ubuntu 12.04, if that matters.

Answer 1

I managed to fix it. The problem was that ibus was redefining the shortcut, so I removed this shortcut configuration.

Enter ibus in dash:

Then select Keyboard Input Methods . From there, click on the first three dots next to the Enable or Disable text box. The following windows should appear:

If there is anything related to Ctrl + Space , just delete it.

Answer 2

In my case; Window> Settings> Java> Editor> Content Assist> Advanced

Make sure the offer> Template Suggestions, SWT Template Suggestions, Java Suggestions, Content Support Console> Template Suggestions, SWT Template Suggestions, Java Suggestions is selected.

Answer 3

Go to Windows> Preferences> Java> Editor> Content Assistant> Advanced> select only Java. If you select all, then multiple instances of the same instance will be shown in the list of offers. which can be annoying several times.

Answer 6

This happened to me. What I did was change the workspace folder to another folder and the problem is solved!

Answer 7

This problem happened to me, and none of the stack solutions decided to solve it. I finally realized that some other Windows tasks stole my hotkey. If nothing works, I recommend that you download the free Windows Hotkey Explorer software that reports registered hotkeys.

In my specific situation, I found that ctrl + space was captured by the blackboard cooperate command (an unattractive Java webcast application used by some of my courses).

I closed Eclipse, killed all java processes (including the board). A launched eclipse and my autocomplete are back!

(Note: Hotkey Explorer was an incredible mistake and crashed every time I used it. I was able to get the information I needed before it crashed, although it was useful. Another (shareware) application that I did not use, but noticed Online: Hotkey Commander .

Answer 8

Although I configured the eclipse suggestion options, it did not work for me. In my case, the Ctrl + space bar combination was hacked by another background running process (I ran the AllwaysOnTop utility for Windows). it worked after exiting this process. :)

Answer 9

Ctrl + space did not work in my eclipse. Somehow he disconnected.

I tried many options and no options worked.

Finally it was working

Go to "Settings"> "Java"> "Editor"> "Content Assistant"> field "Automatic activation triggers for Java:". Insert "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz." (note the point after z). This is the best solution and you don’t even need to press Ctrl + Space.
