Now I use eclipse CDT but one thing really annoys me.
See this picture:
I cannot use the scroll bar. It only shows up when I move my fingers up and down on my trackpad, and disappears quickly. But scrolling up and down in this way is really inconvenient!!
Edit
Okay. I do not fully solve this problem, but now I find a way to relieve my pain. Window ->Editor ->Toggle split editor. Then, the editor panel is splitted into upper and lower parts, showing different parts of the same file. And in this case, I can drag the scroll bar up and down!

I'm new to Eclipse. One of the things I like most about it is the fantastic indexing, and the symbols/function outline at the right. One of the things I like least about it is how small the code area is due to all of the side-bars (one each in Eclipse CDT at the left, right, and bottom makes the code area quite small).
Is there a quick way to toggle between hiding and showing the sidebars?
After some tinkering around I accidentally discovered it! Just double-click on your open file-name tab and it will maximize to full-screen. Double-click again to toggle it back to your normal "perspective". This applies to the left, right, and bottom sidebars too: just double-click on any of their tabs and they will maximize. Do it again to toggle back to normal size.
I don't know if this is the right place for it. Using Eclipse 4.6.2 on OSX, in the Java view, I used to have a bar on the bottom with Problems, Tasks, Console, Properties, etc. tab options. This bar is now small icons on the right. It appears on the bottom when I click on the right bar, but it disappears as soon as I click on any editing tab outside of it. Clicking and dragging the bar to the bottom doesn't have any effect. It has a restore-window style icon that doesn't seem to do anything.
I'm also finding that when I select a .java file, like in Problems or Call Hierarchy, it shows up on the bottom, when it used to pop up above the bottom section.
I've always gotten really confused whenever I've tried to mess with the default views/perspectives in Eclipse. I probably made this happen by mistake. I want to revert to the original behavior, but I'm not sure how. Any advice?
On the top there should be a "window" menu bar. If you look in the window bar you should get a "reset perspective" option.
To scroll within the Eclipse editor without moving the cursor up and down one can use CTRL+Down or CTRL+Up. But what about left and right?
It is not possible. If you search keys in Eclipse's Preferences, you will find out that you only have Scroll up and Scroll down that you can set hotkeys on.
My recommendation would be changing the maximum line length in the editor.
Make your code shorter. After all, looooong lines of code are not so readable.
Also, resize your editor area. If you feel strangled, remove the Outline, TaskList, and Build view from your right side of Eclipse, and enlarge the editor.
Recently switched from Linux to Windows for development in Eclipse Indigo SR1. In Linux, if I Ctrl-Space'd to open a Content Assist window, I could immediately start scrolling with the mouse wheel (with the cursor over the Content Assist window of course).
Now, in Windows 7, if I try to scroll in the same way the Content Assist window goes away, and whatever editor I have open is scrolled instead.
If I first press Tab to give focus to the Content Assist window, the mouse wheel scrolling works as expected, but I'd much rather it behaved as it did for me on Linux, rather than retrain myself to press Tab every time.
Is there a way to make the mouse work this way with Eclipse?
Found an answer that appears to work. It's a little dated but seems to still do the trick.

Dropped this jar in the eclipse plugins folder and restarted. At first I thought it didn't work, but later I noticed there is a little X button added to your toolbar that you need to toggle. Scrolling seems to work properly now.
I've been trying to find a way to scroll the text horizontally with my scrollwheel in Eclipse, similar to the way you can do it in Textpad. In Textpad if you hold ctrl while you scroll vertically it will scroll horizontally. Does anybody know if there is a configurable setting somewhere in Eclipse that will allow this? I've looked all over the "keys" setting page without being able to find it, and Google/Stack Overflow searches haven't turned anything up for me.
Thanks.
I guess this depends more on your OS than on Eclipse. For instance on Mac OS it's Shift + Scrolling.
#Daniel Sokolowski's answer was almost working. I have been using X-Mouse Button Control for over a year now and didn't know how to get the Horizontal Scrolling to work on certain programs (like Eclipse and Chrome) until I read Sokolowski's answer which pointed me in the right direction.
For the sake of brevity, and not to duplicate what has already been written clearly by Sokolowski, follow his directions, and in addition do the following:
Add Eclipse to your Applications list in X-Mouse by clicking Add and finding javaw.exe in the "Choose Application" popup and clicking OK.
Now click on the "Eclipse" profile and choose the "Scrolling & Navigation" tab
Under the "Advanced Window Scrolling" choose Method 1(SCROLL Msg) option for Scroll Method
Click Apply
If you correctly followed Sokolowski's and my instructions together you should be able to press Shift while scrolling up or down to trigger a horizontal scroll.
On a Windows machine this worked for me:
Download X-Mouse Button Control
In the main window go to 'Layer 2' and change 'Wheel Up' and 'Wheel Down' to 'Scroll Windows Right' and 'Scroll Window Left'
Go into the 'Settings > Modifier Keys Tab' and select 'Shift' for the 'Activate Layer 2' setting.
Now in whatever active window, including Eclipse pressing shift and then scrolling up and down will scroll horizontally.
Update: I have been using this approach for a few days now and noticed that not all windows are horizontal scroll enabled, for example 'Package Explorer' is not but 'Navigator' is - this appears to be a limitation of Eclipse IDE rather than this approach. Please take a moment and upvote this Eclipse Bug #201984
You have a plugin supposed (not tested) to support horizontal scrolling.
But without plugin, SWT does not support horizontal scrolling on Windows.
Its support is planed for 3.6 though. (since 3.6M2, actually -- September 18, 2009)
New event constants have been added for horizontal mouse wheels.
See SWT.MouseHorizontalWheel and SWT.MouseVerticalWheel.
For me the best way while using eclipse or for that matter any IDE, is to have a new line char at the end of screen. I feel that to use horizontal scrolling to view data becomes bit difficult while going back and forth and I would like all code to be visible to me always. If the code you are trying to view requires you to use horizontal scroll bar then try to format it by using Ctrl+Shift+F.
The bug has been fixed in the latest update of Eclipse.
In your Eclipse menu bar, simply:
1. Click Help>Check for Updates.. (and wait for the progress bar at the bottom to finish checking)
2. Install all updates.
Once Eclipse IDE gets restarted, you are now able to scroll horizontally.
(Save yourself from having to install additional mouse softwares to create new configurations. Phew, I'm so glad I figured this one out for myself)
Cheers!
