I'd like to have auto completion in Eclipse the way I am used to it from VS.
When typing an open bracket the selected entry from the completion list is selected (Eclipse does not auto complete than)
If the first point is not possible and I press enter, I'd like Eclipse not to insert brackets (I disabled inserting closing brackets already).
Any thoughts? Thanks,
Philipp
you mean triggering code completion here:
myMethodCall(<^Space
If so, AFAIK this is currently not possible. Did you consider to report an enhancement request on this at Eclipse JDT?
You may also have a look on http://eclipse.org/recommenders which may be somewhat related to what you are looking for. Maybe you can start a discussion there about how you expect code completion to work in Eclipse in the recommenders forum here: http://eclipse.org/forums/eclipse.recommenders

I have a quick question that might save me a few seconds of annoyance every day. I know that eclipse can do a lot of autocomplete magic, so this might be possible:
As a programmer who learned with python, I constantly forget to surround contitions in control structures (like if or while) with parentheses. How do I make eclipse autocomplete opening and closing parentheses when I finish typing while or if?
I am aware that I can autocomplete whole structures with ctrl-space, but how can I configure eclipse to do this by itself?
Any help is appreciated.
So in stock Eclipse, the usual way to bring up assisted content is to type Ctrl+Space. The problem with this is that it brings up both Help Proposals and Template Proposals, with the Help Proposals displayed first. You end up wasting time scrolling down to find what you actually want from the Template Proposals. And there's just that much more clutter to choose from.
The solution is this:
Go Window->Preferences->General->Keys. In the type filter text search for "Template". This should bring up a "C++ Content Assist (Template Proposal)" line. Click on it. Now map this to whatever shortcut you'd like (I did Shift+Space because that's an easy one to do while typing). Make sure to click on the "Binding" option to do this. Click "Ok" and you're done!
If you ever want to add or change what is brought up by that shortcut, and for which specific strings it works, just go Window->Preferences->C/C++->Editor->Templates and you can edit those to do exactly what you'd like when using that newly assigned shortcut.
Hope this helps.
EDIT: I am unable verify if this works for PyDev, as I'm running Eclipse Oxygen, which doesn't currently offer PyDev or the Eclipse Marketplace Client plugin. However, my guess is this would still work in PyDev. Best of luck!

Setting auto complete shortcuts in Eclipse
How to change the Control+Space autocomplete shortcut keys in Eclipse for Android
Thanks for any help, but the only thing that seems to work are workarounds. My prefered "solution" is to change the Auto activation triggers for Java in Preferences>Java>Editor>Content Assist from . to .iwfs, so that the autocomplete dialog automatically pops up when I start typing if, while, for or switch. Then hitting enter will do exactly what I needed.
I recently had to work on a visual basic project. For this task I used Visual Studio 2010 and noticed I slight difference how method are proposed for code completion. If you hit CRTL+Space and start typing, all methods are suggested that contain the text. Eclipse suggests all method that start with the text.
This behavior is especially helpful if you have to work with unknown code. Can I achieve the same behavior for Eclipse? Thank you!
You can download Eclipse Code Recommenders plugin - http://www.eclipse.org/recommenders/. It has a feature 'Subwords Completion' which does exactly what you are looking for.
The closest you have in Eclipse is support for camel-case... This allows you to type "new NPE" ctrl-space and Eclipse will propose NullPointerException and NoPermissionException (depending on your current target platform).
To see which preferences you have to change the behavior of the quick assist functionality, open the Preferences Dialog and type "assist" in the search field... There are plenty of ways to tweak the behavior :-)
is there any way, to enable a dropdown list of methods or functions, on the Editor Toolbars of NetBeans 7, like VS does? , i mean the toolbar that is inside on the tab of each file when you are editing a code, that has some options like, "last edit, next breakpoint, next bookmark, ..."
In VS is really helpful this feature, to jump of functions o methods more quickly, i know that netbeans has the navigator, but sometimes this help more

There is no way provided by standard NetBeans IDE offering or certified plugins available in NetBeans Update center, but a NetBeans plugin can be written for doing what is expected in your question. Has it been done? In my opinion no, as no one asked till now. Now that you have asked someone may think of developing such a plugin.
Best way to expedite such request and feature to be added to NetBeans is to add a Request for Enhancement in the NetBeans issue tracker.

There are many ways to reach specific methods in NetBeans IDE. You have already listed one and that is Navigator. Others include GoTo Type [CTRL+O] and GoTo Symbol [CTRL+ALT+SHIFT+O]
Is it possible to make the code-completion on Netbeans automatic, like on Aptana or Visual Studio?
I've noticed that Netbeans can sometimes take a while to populate the list, so this might be asking a bit too much, but if possible, I'd like to somehow enable it.
The onlything I've found in the options is the ability to set a custom key-combo, but not to make this automatic.
I know that if you wait a bit, the auto-completion shows up anyway, but I want it to be without delay.
It appears there is a setting in some NetBeans versions that sets the delay for the popup window.
Choose Tools | Options
Choose Advanced Options
Open the Editing and then Editor Settings folders
Select Java Editor and find the Delay of Completion Window Auto Popup property
Enter a new Delay value in milliseconds (default is 250).
Article where I found it: http://www.informit.com/articles/article.aspx?p=519945&seqNum=5
The problem is that this article is a couple years old, so I opened NetBeans (6.1) on my computer and looked for the property but it didn't exist for the Java Editor (It did for other editors like the XML Editor). This leads me to believe my version is newer than the one in the article and the delay property no longer exists for the Java Editor (checking couldn't hurt though).
So instead, I decided to test the delay. I made a sample project, imported and instantiated a list, and then went to call a method. I stopped at the dot to let NetBeans offer suggestions and it was basically immediate (no noticeable delay). It is at this point, I am wondering if the delay you are experiencing is due purely to performance of the computer, especially since you indicate this occurs "sometimes". It is possible that you are looking at rather large classes, and NetBeans is taking extra time to look up the completions. You could try and test to see if this is true or not by testing code completion on a known large class. The other possibility is your computer is not as fast, or is doing work for another program at the same time. You can try and test this by restarting the computer, opening only NetBeans (to maximize resources to NetBeans), and try some code completions. If either exhibit noticeably faster delays, this is most likely the problem.
Hope this helps.
I think I found a solution. I set up autocomplete keyboard shortcuts for all letters and #, it seems to work. In some cases there is a small lag, but it doesn't prevent you from typing. It took about 5 minutes to add those shortcuts.
I tried to get the desired feature by adding the alphabet to the completion selectors. It worked somewhat, you can always try it.
This works for the first two characters you type This is updated one

Is there any way to save my code folding in eclipse?
It's horrible to scroll trough my entire UI declaration. (And yes, I googled it! :)
The question is very similar to Is there a way to collapse all code blocks in Eclipse? .
I'm re-posting my answer there here.
The question is a bit old, but let me add a different approach. In addition to the above hot-key and utility approaches, there are default preference settings that can be toggled.
As of Eclipse Galileo (and definitely in my Eclipse Version: Indigo Service Release 2 Build id: 20120216-1857) language specific preferences can open up new files to edit which are already collapsed or expanded.
Here is a link to Eclipse Galileo online docs showing the feature for C/C++: http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.cdt.doc.user/reference/cdt_u_c_editor_folding.htm .
In my Eclipse Indigo I can open the Folding Preferences window via : menu/ Window/ Preferences/ Java/ Editor/ Folding and set all options on so I can open files by default that are completely collapsed.
Amongst other things, Mylyn allows you to fold/hide content and persist the state.
Mylyn monitors your work activity to identify relevant information, and uses this task context to focus the user interface on the task-at-hand. This puts the information you need at your fingertips and improves productivity by reducing searching, scrolling, and navigation. By making task context explicit Mylyn also facilitates multitasking, planning, reusing past efforts, and sharing expertise.
Once Mylyn is enabled it will start folding/hiding the content. If you have an active task (can use a local task repository) the state should be persisted between sessions. Alternatively you can attach the state to the task (sorry don't have Eclipse to hand to check the exact method to do this) then retrieve it. This is useful if you are sharing tasks with others.
I know this isn't exactly what you were asking, but this was really helpful for me:
Ctrl+Numpad_Multiply can also be used
to expand all
Ctrl+Shift+Numpad_Divide is bound to
collapse all
Ctrl+Numpad_Divide toggles folding on
and off
(Taken from this post: Is there a keyboard shortcut in Eclipse to fold the current method/block? )
This, and plenty other issues of Eclipse made me switch to JetBrains IntelliJ IDEA. It's worth sneaking a peek at it if you find Eclipse's performance annoying, need more control on your code formatting or if you just want to have your code foldings persisted.
I'm not using it for too long now but it seems pretty handy for anyone developing in the Java, Android or Scala corner.
