I'm using Eclipse Kepler (4.3) (with pydev, in case that matters). If I collapse my code (using Ctrl-9 or the Source menu) and then selectively uncollapse only the part I'm working on, it works fine for a while. But at some point in the session, I'll notice that Eclipse has randomly (?) decided to uncollapse all the code. Am I doing something wrong, or is this a known "feature" of Eclipse? And is there any way to prevent it?
And in case there's no way to prevent this, I have a follow-up question: Is there any way to collapse just the code I have selected? I.e., can I select a set of functions and collapse them all at once rather than going through and collapsing them one at a time?

I am an eclipse-only programmer.
Now the time has come that I want to try out intellij IDEA to see if it may even suit me better than eclipse does now.
I have some essential shortcuts which I need to work exactly the same as I am used to. And as far as I see, that's not possible. But maybe you guys know it better.
1) Moving lines up and down
In Eclipse I use ALT + UP and ALT + DOWN:
the alt up/down could be done by IDEAs "move down/up" commands in "other":
but they behave differently. Unfortunately "too smart" I'd say... as they keep track of blank lines and skip these, and even carry comments with it. I simply want to move only the selected line, up or down, simple as that.
Example:
results in
and when moving it up or down in Eclipse. In Intellij IDEA this happens:
2) Duplicate Lines up and down
In Eclipse I got these shortcuts, on copying up and the other copying down:
In Intellij IDEA I'd use the "Duplicate Entire Lines" under "Editor Actions", and this suits me very well. BUT: I only can use one direction, up or down, as this command only exists once. I need both... :(
Thanks for any help!
IntelliJ IDEA has Move Line Up/Down and Move Statement Up/Down actions. The latter is smart, the former is dumb. Assign shortcuts and use whatever you prefer.
Vote for this request or use this third-party plug-in.
Plugin for IntelliJ IDEA to allow copy lines and block of code like in
Eclipse IDE (Ctrl+Alt+UP and Ctrl+Alt+Down).
I'm using IntelliJ 13 and the Scala plugin. In one project if I make an obvious type error I get a visual indication, like this:
But I just started a new project and a similar thing is not highlighted, even after I compile.
I'm giving a presentation on some Scala code and I'd like it if the type errors highlighted like in the first one, but I have no idea where the setting is.
One reason could be that the level of highlighting is set to a lower setting. Check your lower right corner for a button which adjusts this setting with a slider. It looks like (at least to me) a policeman face :)
Another thing is that you might not have declared what additional languages you're using besides the primary one. You can configure this in the project settings.
Also if you are using a tool to build a project (like Maven for example) try rebuilding or reimporting your project.
edit: One last thing. Make sure IDEA isn'currently reindexing or running some background tasks, this really messes up code correction.
I never had this issue with Eclipse before (Eclipse Classic 4.2.2, Indigo) but it started happening on my new iMac recently, that it stops highlighting similar occurrences or variable names, etc. Then it automatically starts working just fine.
Needless to say its a pain when it doesn't show the multiple occurrences of variable names and I have to find them using Find.
I was wondering if there is a sequence of keys which I press by mistake which causes it? I haven't find an answer to this anywhere else yet.
Attached is the screenshot from the Preferences. As I edit this question, again the Mark Occurrences is greyed out and I'll have to check it again to make it work.
A work around for this is to click on e.g. the Outline view, and then click back on the editor. The mark occurrences should start working again. I don't know of a long term fix.
I often end up with lots of empty panes in Eclipse that can only be minimized but not destroyed. How do I close these?
Update:
In this screenshot you can see two minimized on the upper left and several on the right hand side. In the center are four more. They only seem to be restorable in the Debug mode.

this happened to me, too. What worked for me (based on FilmJ and douncon's comments) was to open a class file, then drag that tab over the top of the empty pane.
Select Window -> Reset Perspective. That should reset the current perspective (what you call "mode") to its' initial state, (hopefully) closing all irrelevant views.
Something seems terribly wrong with your Eclipse. Maybe you should reinstall it. It is possible that you installed a buggy plugin.
First of all, what do you mean by pane? Eclipse has:
Windows (Eclipse itself, e.g. instance)
Documents (tabs)
Views (properties, tasks, explorer, etc)
If by 'pane' you mean document editors, you have problems either with your Eclipse version or most likely one of the installed plugins.
Each View also can be closed (except maybe some project types (perspectives) of which I'm not aware). For CDT (C/C++) you can close practically everything.
I'll recommend you download latest Eclipse version with no plugins, extract it to different folder, and check if that happens again. If yes, please explain more in details (like Eclipse version, perspective you are using, any side plugins, etc).
Also a good places are Eclipse community forum, mailing list and bugz :-)
I had the same problem. For me it helped to go into the right perspective and activate the functionality that caused the window in the first place. Once I reactivated the functionality, in my case "QNX Memory Analysis perspective", I was able to close all the windows one by one.
The conclusion is you have to refill the empty windows with content and then you will be able to close them properly.
So, it's really very easy for this to happen, if you open an editor that's incompatible with the existing editor, you can often end up having to place it outside of the tab list in one of your editor panes, then you might clear or copy that, typically while trying to add that view to a tab list.
In any case, what it's done is create a new editor, and all you need to do is drag some file to that empty editor window giving it some form of context, then close it.
I had the same issue. I followed #zvikico, but instead of just resetting, I first reset and then closed all the perspectives. Please follow the following to fix the problem. It worked for me:
Window -> Perspective -> Reset perspective..
After resetting follow below:
Window -> Perspective -> Close All Perspectives
Sometimes when I jump into source code, e.g. from search or when looking up the declaration of something, the Eclipse text editor tries to display nearby long lines by horizontal scrolling. This happens even if the item I jumped to is well within the display without scrolling. I find this rather annoying, so:
Is there a way to disable this? I have searched in vain through all the editor settings.
Specifically, this is about Eclipse CDT, but I suppose the behaviour is the same in JDT.
This seems to happen in other eclipse editors too (like PDT for PHP)
It could have been related with the ScrolledFormText, but the Plugin Spy tells us a WorkbenchWindow class is concerned, as well as an AbstractDecoratedTextEditor, that is in essence an org.eclipse.ui.texteditor.AbstractTextEditor.
The source of that AbstractTextEditor indicates having:
a ScrollLinesAction for vertical scrolling
a TextNavigationAction for settings the cursor and potentially triggering horizontal scrolling
I am not sure how to change that behavior, except by contributing somehow to the active editor identifier (for instance, for java, "org.eclipse.jdt.ui.ClassFileEditor"), and modifying that Action.
I was having the same issue and found these open bugs for it on the Eclipse Bugs:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=314208
https://bugs.eclipse.org/bugs/show_bug.cgi?id=321189
You can prevent it from happening when you switch the Code Folding off and reload the file.

right click on your eclipse shortcut and choose properties. in compatibility tab choose "windows xp(servicepack 3). http://www.vistax64.com/vista-general/133849-disable-dynamic-horizontal-scrolling-vista.html
