When IntelliJ IDEA detects I'm pasting a piece of copied Java code into a Kotlin file, it offers me to convert the pasted Java to Kotlin. This dialog contains a 'Do not ask again next time checkbox'. I checked this box and selected 'Yes', but now I want to undo my default choice. How do I do this?
I've looked and searched in IntelliJ IDEA's preferences, but haven't found the respective checkbox. Is it actually in the settings, or can I somehow reset default checkbox selections?
Preferences -> Editor -> General -> Smart Keys and somewhere down below you should find your checkbox (took me a while to find this, phew)
I am working on an xml file inside of Netbeans and something changed in my settings where when I open up a bracket, it turns the bracket red and displays the Javadoc in addition to the code-completion tool.
I like the code-completion but not the javadoc. Does someone know how to turn it off the Javadoc?
I found out the answer:
In Netbeans, go Tools -> Options -> Code Completion -> uncheck "Auto Popup Documentation Window"
I'm still not sure what keyboard shortcut I hit to enable it in the first place, but this turned it off.
I got to InteliJ from Eclipse. So, I am programming in Java (for Android) in InteliJ now.
I have problems with FOLDING (collapse/expand) style in IntelliJ.
This is a sample of code folding in Eclipse (and I love it) :
and This is code folding in Intellij (or Android Studio) and I hate it :
Is it possible to convert code folding style in InteliJ to Eclipse? (Eclipse folding is my target)
I want to hide #Override or any annotations from all methods in IntelliJ
I want to hide folded symbol {...} or move it in method name line in IntelliJ
Like this :
(in following picture, I removed #Override manually. so,I've moved to manually bracket { to the method name line.
)
Update 1 :
I tried to solve my problem in (Intellij) File -> Settings... -> Editor -> Code Folding , but I could not solve.
For Android Studio:
File --> Settings --> Editor --> General --> Code Folding
From that section you can select the way you want to fold your methods and inner classes etc.
Hope this helps.
You can change it by changing code formatter style.
For Mac :
Eclipse -> Preference -> Java -> Code Style -> Formatter -> Edit
For Window :
Window -> Preference -> Java -> Code Style -> Formatter -> Edit
Please check below links for more details.
http://www.wikihow.com/Change-the-Default-Format-Settings-in-Eclipse
Open Eclipse.
Click on the top tool bar and then click on Preferences.
On the left side of the box, expand Java option, expand Code Style, and click Formatter.
The active profile must be set to Eclipse[built-in], you cannot edit this setting, so make a new one by clicking the New... button.
Enter your new profile name and click OK.
You will now be presented with the "Profile 'name you set'"box.
There are 8 tabs: Indentation, Braces, White Space, Blank Line, New lines, Control statements, Line wrapping, Comments.
Click on each tab and make the changes. Dont forget to click Apply.
Now to format the current document, click on Source from the menu bar, click Format or press Ctrl+Shift+F.
Job well done. =)
I'm using the Kleper version of Eclipse. Days ago the IDE was working fine but I made some configurations in Window -> Preferences and my Eclipse doesn't show anymore which classes were changed.
When I say "classes were changed" I mean the symbol '>' beside the class name is gone. Example: > Teste.java
What can I do to fix that?
Probably you accidently changed a setting in General->Appearance->Label Decorations? There you can enable/disable annotations ... e.g. CVS anntotations.
It depends of your versioning system, but in general this is set in :
Window -> Preference -> Team -> your_version_system -> Label Decoration
in the Text Decorations tab.
Update
This was fixed in Eclipse 2018-12. This behaviour is still default, but can be configured off - see the accepted answer for how
I'll leave the question as it was for posterity, and for those on earlier versions of Eclipse
In Eclipse, I've enabled intellisense-style suggestions for Java by going to
Window -> Preferences -> Java/Editor/Content Assist
and setting the following
Auto activation delay (ms) -> 0
Auto activation triggers for Java -> .(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
source = Eclipse Intellisense?
This works brilliantly, apart from one annoying problem. When I hit spacebar, the token being typed is autocompleted with whatever is at the top of the suggestions list. Fair enough, except that sometimes I'll type a class/variable name with an exact legal match, but this won't appear as the top suggestion. So when I naturally hit spacebar Eclipse inserts something completely wrong.
E.G. after typing Cookie I'll hit spacebar and get CookieMonster.
This seems like a bug, and happens often enough to be annoying, but even despite this I don't want spacebar to trigger autocomplete in general. I may want to type a variable name which hasn't been declared yet, or something similar. I want to use autocomplete as a helper tool, but my natural typing should always take priority over it.
I'd like to stop spacebar triggering autocomplete, and either fall back to using enter, or better still trigger autocomplete with a custom key not used in ordinary typing. Is any of this possible?
I've played around with all the settings in Content Assist to no avail. Googling the question just returns a bunch of results about disabling the autocomplete feature.
This issue is fixed from Eclipse 2018-12 [4.10] see the accepted answer
It's present in all prior versions, i.e. 2018-09 [4.9], Photon [4.8], Oxygen [4.7], Neon [4.6], etc..
Eclipse 2018-12 was already patched for this!
A patch for Bug 348857 was recently merged to the Eclipse project and was released as part of Eclipse 2018-12. You can download that version here.
You now have a new option to disable all insertion triggers apart from enter, which will prevent spacebar from causing autocompletion.
Simply go to Preferences... -> Java -> Editor -> Content Assist (or Window -> Preferences -> Java -> Editor -> Content Assist on Windows) and select Disable insertion triggers except 'Enter', as shown in the screenshot below:
There is a solution on the issue tracker for this.
Copy the jar in the eclipse/dropins folder. With the next restart space is diabled as autocompletion trigger.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=348857
Eclipse 12-2018 and newer: This is working natively, check Pyves answer.
Use a SDK version of eclipse
1.open Plug-ins View and find org.eclipse.jface.text, right click, choose import as Source Project. After import, you find it in your workspace.
2.In src/org/eclipse/jface/text/contentassist/CompletionProposalPopup.java
char[] triggers = t.getTriggerCharacter();
if(contains(triggers,key))
change to
if(key!='='&&key!=0x20&&contains(triggers,key))
3.Export org.eclipse.jface.text
Right click the project folder of org.eclipse.jface.text, choose export-->Deployable plugins and fragments, next, destination choose archive file, finish. Replace the one in eclipse/plugins with the one you generate.
The spacebar has been a key to select the autocomplete even in Indigo. To my knowledge, this can't be configured.
In fact, that is probably why the delay exists.
I suggest setting the delay to some optimal value that allows you to type things like private void ... comfortably without triggering suggestions for private and void. Then in case you get a suggestion because you waited too long, press Escape to abort Content Assist.
Same configuration as davnicwil, same issue, still on eclipse 4.4.
Solution: Intercept (hook) SHIFT+SPACE (press and hold) on (editor-window) eclipse and replace it with ESC,SPACE (sequence). Now you my decide between
Autocomplete+SPACE: press SPACE when autosuggestion present
just SPACE: press predefined key combination or sequence (e.g. SHIFT+SPACE)
On windows you may use http://www.heise.de/download/activaid.html (you can also use AutoHotkey, java native hook, ...)
HowTo with ActivAid:
Open Ac'tivAid, select "UserHotkeys"
click on "+", set a description
click on "short cut", press e.g. SHIFT+SPACE
Command: "{ESC}{SPACE}" (without quotes)
click "+", select eclipse editor frame, press ENTER
click OK, OK in Ac'tivAid
My config file:activAid/settings/ac'tivAid.ini:[UserHotkeys]
Hotkey11=+Space
Path11=<Send>{ESC}{SPACE}
Description11=Eclipse Shift+Space -> Esc,Space
Category11=
Application11=ahk_class SWT_Window0
You may also remap keys on non-english keyboards with "HotStrings", e.g. ö->{,ä->} etc.
Finally worked it out.
Try download this org.eclipse.jface.text.jar and copy it to your plugin folder(Typically eclipse/plugin). Do not forget to backup your own one.
Works on Eclipse Juno.
If the link doesn't work, comment on this, thanks.
In Eclipse go to Window -> Preferences -> General -> Keys and remove the binding for the command Content Assist.
You could disable Auto activation via the check box in
Window -> Preferences -> Java/Editor/Content Assist
and activate the auto-complete feature on demand. The default hotkey for this is
CTRL+Space
