I don't know if anyone has noticed that Eclipse has this annoying feature where it needs to show a useless tool-tip when hovering just about anything.
I was wondering if anyone knows of a way to completely kill all tool-tip behavior in Eclipse / Aptana?
Thanks
I found mine in Window > Preferences > Pydev > Editor > Hovers
It looks like it's a module-level feature (Java, Pydev, C++), not platform-level (Eclipse itself).
Window > Preferences > Java > Editors > Hovers
Disable Combined Hover.
I agree, hints can be really annoying, but there are times when they can be a really useful quick reference - like finding var values during debugging, or required parameter types for a method etc.
So instead of disabling them altogether, or continually enbaling/disabling through the Preferences, I go to Window > Preferences > Java > Editor > Hovers > Combined Hover, and add Alt to the Pressed key modifier while hovering field below.
This way if you want to quickly see hints just hold the Alt key down.
I was completely annoyed with Aptana's tip tool text over my code. I figured out how to disable it:
Window > Preferences > Aptana Studio > Content Assist > Show information on hover > Off
I'm using Aptana 3.
Another thing which really annoys me on Eclipse are the light bulbs in the left part which hide breakpoints, and which are really useless.
To suppress these, go to windows>preference>java>editor and then uncheck "Light bulb for quick assists".
If you dont have this on your eclipse version, try a help search with "light bulb".
This is the answer. Change the Windows regedit.
HKEY_CURRENT_USER ->Control Panel -> Mouse -> mouse -> MouseHoverTime
Change its value to be 400 (4 seconds delay)

Look for TweakUI settings, under Mouse > Hover. Minimize the sensitivity and increase the time and you will, in most cases, be fine.
Note that this is under windows. In any case, search for "hover" and you should be able to find the correct location. Good luck!

I am Using Eclipse for android, I have installed SDK ADT bundle. While coding, some times I need to know description of Classes, Methods etc. When I hover my mouse over class, method definitions, it does not show the tooltip, after some time it begins to show it. This goes on and off. Can anyone help me solve this problem? Thanks!!
Go to Window > Preferences > Java > Editors > Hovers
select Combined Hover.
You can restart Eclipse for good measure.
How do you disable content assist in Eclipse?
I do not mind allowing it to come up when I press ctrl & space, but I do not like how it automatically comes up as I am typing. It just messes me up. For instance it, I would end up scrolling through the options when I just want to go up a line. It is getting tedious having to press escape whenever it decides to pop up.
I have found the page in the preferences for it, but I cannot seem to find out how to disable the auto-pop-up.
EDIT: I am using the application for android development. I have already disabled "auto-activation" for both Java and XML, but it does not seem to have an effect. The window will still pop up automatically.
EDIT2: I tried restarting the program after making the changes, but it still had no effect. I made sure that the option changes were still in effect, and they were still in effect.
This Eclipse3.6 Help page on Content assist can help (it is for C++, but the same idea applies for Java on the Java > Editor > Content Assist preference page.):
The idea is to disable what triggers the content assist.
Go to Window → Preferences.
In the filter text search bar, type "typing".
Go to Editor → Typing.
Uncheck all that you don't want.
Don't know if you did get it to disable but I was having the same trouble as you.
I did the following:
Window > Prefrences > Content Assist
Uncheck all and hit apply
Java > Editor > Content assist > Advanced
Uncheck all and hit apply.
Hope this works if you still haven't found an answer.
It's not readily obvious and there doesn't appear to be a global option to turn it off all over the place. This may sound obvious, but it's important to make sure to turn off Auto-Activation on all of the different structured editor types that you do not want it active on.
In Eclipse Mars.1 :-
go to Window then->preferences -> Java -> Editor -> Content Assist ->Advanced -> Restore Default ->Apply and then OK.
Go to Window -> Preferences -> PHP -> Editor -> Content Assist -> Auto Activation
Untick the box "Enable auto activation"
I am using Eclipse to program Android apps and I love how the little helper box thing comes up when you start to type and suggests things to you.
However, this only happens sporadically and I was wondering if there was a way to keep it visible for longer or, even better, a key combo I could press to bring it up. If I start to type something, it either helps me by suggesting things or doesn't appear.
Try Ctrl+Space. The feature is known as "content assist," "code completion," "auto-complete." In the Visual Studio world, I think it's called "Intellisense."
If you want the suggestions to appear immediately (I prefer this) you can change the delay by going to Window → Preferences → Java → Editor → Content Assist and change the Auto activation delay to 0. In my version of Eclipse (Helios for Java EE), that field is third from the bottom.
An easier way of finding this preference screen is to use the search box in the upper-left-hand corner of the prefs (as before, Window → Preferences), and typing completion. From there you can see all of the different content assist preferences that Eclipse offers. Mine has Java, JavaScript, CSS, HTML, JSP, and XML - most of those because I'm using a fancier version of Eclipse.
By default, when writing Java code, the . (period) key triggers auto-activation of content assist. You can change this setting in the same screen as the auto-activation delay.
I think its Control+Space for Code completion. Try that
Also go easy with the code completion popup delay. Dont set it to 0, i remember a strange behaviour in Eclipse where there was no popup at all.
Ctrl+Space is the shortcut for Content Assist.
Ctrl+1 is the shortcut for Quick Fix.
Ctrl+2 is the shortcut for a menu of Quick Assists. (Ctrl+2, F is the shortcut for Quick Assist - Assign to var/field, and in place of F you can also type L or R for other options.)
To see and/or modify available shortcuts you can go to Window > Preferences > General > Keys.
Somehow I've turned on hidden characters in Eclipse. It's not the "whitespace" characters in the general editor preferences. When turned on, it adds another layer of hidden characters over the existing ones.
Then I have things like
\r\n
Does anyone know what these are and how to remove them?
It is under Preferences > General > Editors > Text Editors. There is a checkbox labeled "Show whitespace characters". If you uncheck this the editor switches back to normal.
If you click on the link (whitespace characters) (<= v3.6) or (configure visibility) (>= v3.7) in this line you will get a popup window, in which you can define which characters eclipse is supposed to consider as whitespace characters.
In this popup window you also get the option to define the transparency in which each whitespace character is displayed in the editor, which you can use to (indirectly) change their foreground colour. I'm just mentioning it here, because it took me about half an hour to find this setting! ;-)
There is a toggle button 'Show Whitespace Chars' on the Eclipse toolbar
A great tip about using 'quick access' from eclipse forum:
CTRL+3 swc
Allows to turn them on and off
The right shortcut is Ctrl + N
UPDATE From Eclipse 3.7 version, something is changed... Now you have to go to:
Window > Preferences > General > Editors > Text Editors
CTRL + . does the job.
For Aptana Users
To toggle hidden characters in Aptana on and off, use the following keyboard shortcut:
Ctrl+Alt+W
I am using Eclipse Oxygen and can see this option to toggle whitespace characters:
It is actually in two places...
Sandkastenliga points out the obvious one, but you can also show white space with a shortcut key combination. The key combination is separate from the text editor preferences and will superimpose additional characters when active (it uses \r and \n for carriage return an line feed respectively instead of the symbols used by the text editor preference.)
Go to preferences > general > keys and look for the binding for the 'Show Whitespace' command.
I have the text editor preference turned on, so I removed the binding for this command altogether (it was set to Ctrl+. in my profile) to prevent accidental activation as it doesn't affect the other preference.
Go to Window > Preferences > General > Editors > Text Editors
Uncheck the "Show whitespace characters" option on the right side of the page, then click "Apply" at the bottom of the page.
Since this is not a standard setting, it could be the result of one of your extra plugin.
Did you try starting your eclipse with the -clean parameter?
Do you reproduce the issue with a fresh Eclipse installation?
Go to Preferences > General > Editors > Text Editors and restore defaults.
I have done this several times by accidentally hitting some keystrokes.
If you go to Windows/Preferences/General/Keys you will see all the keyboard shortcuts you have.
Mine is set to Control + .
I had to place my cursor inside the document and do it a couple of times to make it work because there is also a keyboard shortcut for Control +
Hope that helps.
You can add "Show Whitespace Characters" button in toolbar by customizing your perspective.
It also contains buttons to toggle word wrap, and toggle selection mode.
Go to Window > Perspective > Customize Perspective > Action Set Availability, then select "Editor Presentation" action set:
This works in Eclipse Neon.
You can also add a key binding for this action.
Go to Preferences > General > Keys > "Show Whitespace Characters"
Sorry this is a bit vague but it's a while since i used Eclipse and i do not have it installed. I think this is it ..... in one of the menus you will find the Eclipse settings, there are two set's of settings, current project and overall Eclipse, you mat need to check them both. In there are various menus in tree form that allow you control the actions and look and feel. But some of them are nested so there is an overall control but some packages have their own options in a sub menu set. The menu's will expand when you click them and i'm afraid you need to walk through them all.

A fellow developer dislikes the Eclipse hovering Javadoc and would like to disable it (one option), or, better yet, only selectively enable it (other option). He's using Eclipse 3.3. Is this possible?
Not sure what you mean by "selectively" enabling it. Based on what?
Directions below are for 3.5, I don't have 3.3 lying around to check but I'm pretty sure same settings were available.
Go to Window - Preferences; select Java -> Editor -> Hovers on left hand side. You'll have to uncheck the Combined Hover option on the right; you can then either uncheck Javadoc option or check it but specify a modifier key for it (in the edit box below). In the latter case javadoc hover would only appear if you hold that key.
I've got to say, though, that the inconvenience of not having Combined Handler makes this really not worth it in my opinion.
You could go to
Preferences / Java / Editor / Hover
and untick the "Combined Hover" option: no more popup.
Then you would have:
Shift+F2: open the external javadoc if javadoc archive or directory has been associated with your project (and if some javadoc has been generated)
Alt+Shift+Q, followed by J: open the javadoc view, with the same content than the popup previously seen on mouse hovering.
In Eclipse 3.6 you can now specify a modifier key to be pressed down for the Combined Hover to be activated. This way, you can have the old behavior without the automatic popups. The automatic popups were driving me crazy, often obscuring something I was trying to read.
