I have just installed the 2020-12 version of Eclipse IDE, and I simply cannot get the Ctrl+Space suggestions to work. Every time I try to use them I get an empty suggestion box.
I've already searched for this of course, and I've found many who suggest how to fix it.

Eclipse - CTRL+Space autocompletion does not work any more for Java
https://mkyong.com/java/content-assist-ctrl-space-is-not-working-eclipse/
No Default Proposals in Eclipse Juno
Eclipse/Java code completion not working
Most of these say I need the Other Java Proposals in the settings, but if you look at the image you see that that option doesn't even exist! In the image the default settings are applied but I've also tried to check every single one of those boxes and still get an empty suggestion box when I press Ctrl+Space at the end of Combi (also in the image).

I have downloaded the Mars MIPS Simulator .jar file, and I have downloaded the java jdk file from oracle. Whenever I open the jar file, the IDE is there, but everything is greyed-out. I can't even edit the text in the window. When you select "Execute", three cut off windows appear in the box below, one titled "Text Segment", one "Data Segment", and one "Labels". I am thinking it is a failed installation, but I have no idea what else to do. Thank you for any help!
Here is a screenshot:

Hey I had the same problem! Just use the toolbar on the top and click paste and the edit window should work. And after you hit assemble, go to settings->Show labels window. Hope it helps!
I can tell you this:
I don't think it's an installation issue. As you said, you installed the JDK and then run the program succesfully. An installation issue would be an unexpected error because of a missing dependency, or something similar.
As this is not a programming question, I don't think StackOverflow is the correct site. You may search in the StackExchange site for an adequate community.
However, try putting the cursor at the bottom of the cut off windows to see if you can modify the size of the container panel.
UPDATE
Seems like the problem is that you are not editing a file, that's why the majority of the buttons are disabled. Try creating a new file: click the first button in the toolbar, the white one. Also, the menu item "file" should give you an option to do it.
I'm getting strange results in my Eclipse WindowBuilder whenever I try to run my GUI, the top left area has glitchy text (I don't really know what else to call this problem). I've tried searching everywhere but apparently no one else is getting this problem.
Problems with the image: Display is being displayed as Displa, 'Search' is scrambled.
Problem image:
I've tried creating a new project, tried reinstalling eclipse, deleting all my eclipse metafiles, redownloading WindowBuilder, I even uninstalled Java JDK and Java from my computer and reinstalled it.
I'm running
Windows 7 Ultimate Service pack 1 64bit.
Java 8 Update 25 (64-bit).
Java SE Development Kit Update 25 (64-bit).
Eclipse IDE for Java Developers
Version: Luna Service Release 1 (4.4.1)
Build id: 20140925-1800
Here is my using WindowBuilder process to give you guys an insight, as I maybe doing something wrong:
Create a new project, creating new application window under WindowBuilder. Go to design, add JTabbedPane in the center, and then add JPanel(s), apply GridBagLayout under all of my tabs and then add regardless of what element I put, the first element is always affected by this glitch and so are the tabs themselves affected.
I've tried supplied all the information I can please ask me if you want to know more to try to help me figure out what is wrong.
My layout of GridBagLayout:
Other notes:
I've also noticed that even after clean and fresh installs sometimes or often whenever I add a new element to my GUI after reopening or anything I get a big error and have to spam "Reparse" button a few times before I can go back to editing.
UPDATE:
I also noticed if I type anything in the text fields it will glitch out and I won't be able to see what I'm typing.
Same problem, got it after I downloaded and installed JavaJDK.
Not sure how to fix it other then just try to resize the window a few times, and you might be able to see what it says. Also I by browser doesn't detect my java install.
EDIT:
I found this:
Swing rendering appears broken in JDK 1.8, correct in JDK 1.7
I did what the best answer said and it worked :) And yes, indeed I have NVIDIA GeForce driver and java 8 installed (that is why).
I am from norway so the text is as well... Just try to click on what I have clicked on :)

I never got to updating this question with an answer, the solution was running Eclipse using the Nvidia Graphics card rather than Integrated.
The autocomplete of eclipse is not working now and I searched for hours but I couldn't find an answer to solve it. I haven't used it for long time then the first thing after opening it was to install SWT and windows builder even though I had swing installed. What I mean is, it is may possibly be because of some conflict caused by swt and swing(I read something about a conflict but I don't if this is possible).
Strange thing is it doesn't show anything when I press ctrl+space but when I go Edit-> Content Assist -> Default(it says Ctrl+Space nearby it), it shows things needed to be shown/works as desired.
public class Dsada {
String sssss;
public Dsada(){
sss //pressing ctrl+space is not working,Edit->ContentAssist->Default works fine
}
}
The solution is not to tick/untick some stuff under Windows->Preferences->...->Content Assist-> Advanced. I checked if "ctrl+space" is hijacked by some other thing which is not and checked keyboard language which is English(Those are suggested in mkyong).
I read something about a bug but I couldn't understand. I tried to delete eclipse and re-install again but I guess some settings just stayed in the machine so that it didn't work.
This is recurring for me. I'm using Eclipse 2019-03 in Windows 10.
The steps below work for my case, and does not require a restart.
Window->Preferences->Java->Editor->Content Assist->Advanced
The following options are de-selected, and when I set them the autocomplete worked as before. No restart needed.
1. Java Non-Type Proposals
2. Java Proposals
3. Java Type Proposals
4. Java Proposals (Task-focused)
I don't know what's triggering this but it only happens after I've created a new project. Usually doesn't. It simply doesn't happen often enough for me to notice a pattern to follow up on more.
Clearly this problem occurs with a variety of causes, so review the other answers to see if they match your case.
The hot key combination ctrl+space might be conflict with other settings in system if you are using windows.
Try modify this combination like alt+/, i always use this one since the first time i knew eclipse. It works well.
Hope it works for you.
Window->Preferences->Java->Editor->Content Assist->Advanced
The following options have to be selected, then the autocomplete worked . No restart is required.
Java Proposals (must be selected, not sure the follows)
Java Non-Type Proposals
Java Type Proposals
Java Proposals (Task-focused)
I was facing the same issue. If you use OS X Eclipse Ctrl+Space shortcut can be interfering with OS X system's "Selecting previous input source" using Ctrl+Space shortcut as default.
It is necessary to
edit System Preferencies/Keyboard/Shortcuts/Input Source and uncheck the "Selecting previous input source" or change the shortcut on something else. Eclipse should work after that even without restart.
I faced hot key problem with use Ctrl+Space. I tried to fix the issue first by Windows->Preferences->...->Content Assist-> Advanced and selected
Select the proposal kinds contained in the 'default' content assist list:
Other Java Proposals,
List item
SWT Template Proposals
Template Proposals
Type Proposals
but didn't help.
Therefore, I tried another solution. There would be multiple languages on your computer which could be eating up your Ctrl command. To solve this Go to Control Panel -> Region and Language -> Keyboards and Languages (tab) and then Change Keyboards.
You’ll see a list of languages installed – remove any that you don’t want (click the language and then click the Remove button) until you only have the ones you want left. That fixed it for me, but you can also check the Advanced Key Settings tab to make sure that none of the keyboard short-cuts that are set include Ctrl-Space.
Once you’ve done that, Ctrl-Space should work nicely!!!!
I had the same Problem on Ubuntu 14.04. The problem for me was that ibus used Ctrl+Space as a shortcut. I solved it by starting the program ibus-setup and chaning the shortcut to something else than Ctrl+Space.
Go to Windows >> Preferences » Java » Editor » Content Assist. Then Check the Auto activation triggers for java, Add this in the text box .abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
Recently, I also faced this issue. When I install neon version eclipse.
By (1) deleting respective class, (2) restoring defaults appearance and (3) restarting eclipse, solved the problem for me.
Hope it will help someone.
Go to Preferences » Java » Editor » Content Assist » Advanced. Make sure Other Java Proposals is ticked/checked.
I checked windows has no conflict of ctrl+space (of eclipse autosuggestion) with windows.
This is mere configuration issue of eclipse. reinstallation would fix it.
Thanks.
I select all the parameters in Preferences -> Java -> Editor -> Content Assist -> Advanced.
It help me and resolve the my problem.
Cltr+space work using this step.
Saving my work and restarting Eclipse solved this for me. I hadn't shut down Eclipse in a while, maybe weeks.
I had the same problem (MacOS Monterey, Eclipse 06-2022). Turned out it works with pressed fn button.
For Mac user, you can try : Preferences -> Java > Editor > Content Assist and then :
tick the field "Enable auto activation"
in the field Auto activation trigger for Java, you can input the text alphabet ".abcdefghijklmnopqrstuvwxyz"
I just installed 64-bit Eclipse 3.5.1 on SnowLeopard. I am experiencing a rather strange problem, and I'm posting a question here to see if anyone can explain or confirm it before I go get tangled up with the Eclipse bugzilla.
I open up a Java class with some errors in it. I double-click on a reference to a field. I click right and select 'open declaration'.
The windows then shows me ONLY the declaration. I smell a feature here, but I can't figure out how to get Eclipse to go back to displaying the entire class except by closing and reopening the class.
Go into the Eclipse Preferences and under Java > Editor you will see a checkbox for "Only show the selected Java element"... what you describe sounds like the behavior when that is checked. Try unchecking it.
Good luck.
