Eclipse allows multiple source windows (obviously) and even multiple console windows to be open at the same time.
I'm looking to see if there is a way to open multiple Variable windows at a time. While debugging I sometimes want to visually compare several structures and this would be easier if I could open each object in its own Variable window.
Thanks.
Yes, in the upper right hand corner of the Variables window, there should be a button 'Open New View'.
EDIT: I'm not sure if this is necessarily the best way to get what you want, but it worked for me. I just downloaded a fresh Kepler install, and you can get the "Open New View" button by installing the C/C++ Development Tools. To install go to Help > Install New Software.
Note: I had to clean my workspace after installing because I was getting "Editor does not contain a main type errors". But after that everything worked fine and the button was available.
Hope this helps!

I'm running into an issue in Eclipse where the editor pane is not linked to the project in the Package Explorer window. For instance, if I click on a project in the package explorer and then open a Problems window that is set to Configure Contents > uncheck Show all items > set Scope to On any element in same project, it will show any applicable errors or warnings, but as soon as I open one of the class files with an error/warning in it, in the editor pane, the problems list goes blank as the editor pane does not appear to link the active tab to the active project. Simply clicking the Package Explorer window will then repopulate the problems tab until focus goes back to the editor window/tab.
This used to work with older versions of Eclipse, but ever since I updated Eclipse, it no longer does this and I don't recall which version it was that I had been using. I've also downloaded a completely clean copy of Eclipse Luna (latest version) and simply imported the old projects and still the same issue.
Is there any way to change it so the active tab in the editor points to its associated project? It's quite frustrating having to click the Package Explorer window every time I want to look at a list of problems or tasks for a specific project.
Edit: I've narrowed the issue down to minimized windows only and provided an example of the issue below.
Both windows are restricted to "Show issue on project" rather than showing all issues. Notice how the "Tasks" window works as intended while the "Problems" window does not.
Found the issue... sort of. Apparently, if you minimize the problems tab, then try to access it via the minimized icon for the tab, it loses the correct focusing to tell you what the problems are. My previous version was setup in exactly the same way and had no issues, so they must have changed something that broke this. Going to look at submitting this to the Eclipse team, as a bug.
I'm using Ubuntu 12.10 and Eclipse Juno. This happens frequently: When I put focus in eclipse editor window, I can input few words in editor at the beginning, and then undo several times, Suddenly it happened that, I can't input any word in eclipse, that's strange problem.
Then, I change to other program and input anything, After that, back to eclipse it can accept my key again. It get me so frustrate.
Any one knows this problem? I am using desktop pc, memory is 1G.
This may help;
I guess you have lots of projects in your workspace and Project->Build Automatically option was enabled by default. Disable this and use Project-Build All or Project-Build Project commands before you start debugging your application OR If possible create two workspace and move some of your projects to other workspace. Note that you can open two instances of Eclipse on two different workspaces simultaneously.
Increase heap space for Eclipse.
Its also possible that you installed many plug-ins in Eclipse. You can disable unnecessary plug-ins to load on eclipse start up as shown below
Edit
Two more options.
1. Disable all options in **Highlighted** category of preferences. Restart eclipse.
2. Delete **.metadata** in your workspace and restart eclipse. Note!!!. All you preferences will be lost!!!
I found this problem; It is scim input method conflict with XIM(X Input Method) method.
Solution 1,
just right click in eclipse workspace -> select Input Methods -> SCIM input methods, that's OK. But, Every time you should do it while opening another file.
Solution 2, make scim as default system input methods.
Edit /etc/X11/xinit/xinput.d/scim as below:
XIM=SCIM
XIM_PROGRAM=/usr/bin/scim
XIM_ARGS="-d"
XIM_PROGRAM_SETS_ITSELF_AS_DAEMON=yes
#GTK_IM_MODULE=xim
#QT_IM_MODULE=xim
GTK_IM_MODULE=scim
QT_IM_MODULE=scim
also, add x95input file to /etc/X11/Xsession.d/95xinput
/usr/bin/scim -d
XMODIFIERS="#im=SCIM"
export XMODIFIERS
export GTK_IM_MODULE=scim
Hope this can help others.
I found it.
I googled and found the answer
The answer is:
Right click in Editor area InputMethods-Scim
*Editor area is where you write code
I installed a plugin that allowed me to create UML diagram from my code. Everything was working fine until I found that now all keyboard shortcuts (like CTRL-X, CTRL-Z, CTRL-SPACE, CTRL-SHIFT-F,..) except for CTRL-C and CTRL-V now require a click on a small square that appear on the bottom right corner. And this is required every single time.
This are few examples of the square that appears:
If I click on the message or press Enter I can access the functionality. Does anyone know how to get rid of this annoying thing or at least reset Eclipse related configurations?
Thanks in advance
EDIT:
I obviously tried uninstalling the plugin but nothing changed.
Try Window / Reset Perspective as the duplicate shortcuts may be still in the perspective.
Also try restart specifying -clean option to rebuild the workspace metadata.
The pop-ups you are seeing are the "keybinding conflict" popups. These are common when you have two different plugins defining the same keybinding and looks like these. Still in your case there's only one option to choose from and it definitely looks like a bug.
In the Eclipse bugtracker database there are two issues that are looking like the one you have: #377048 and #374942.
These issues are marked as fixed in 4.2-I20120410-0633. So if you are having Eclipse 4.2 without any service releases installed, you would probably have this. The solution is - to use a newer Eclipse version. Eclipse 4.3.1 is available to download since today, and it should contain a lot of other fixes since 4.2. So I encourage you to install it.
The other solution could be to try playing with keybinding dialog (Window->Preferences->General->Keys) and trying to unbind and re-bind the commands that you are having issues with.
I was evaluating the Enterprise IDE plugin for Eclipse, and ultimately decided not to purchase it. After I uninstalled the plugin, I was left with a bunch of perspective buttons (the ones in the far upper-right-hand corner) which I can't remove. How do I get rid of the manually, without nuking my workspace?
Edit: To be clear, right-clicking and going to "close" does nothing. Not even an error message.
Click Window ► Preferences ► General ► Perspectives. Select the perspective you want to delete and remove it. Some of them are unremovable. I don't know why.
How did you uninstall that plugin ?
As Daniel details in his answer, Help-> Install new software -> click on "Whats already installed?" is the right way to uninstall a plugin, and should get rid of the perspective as well.
If the plugin was installed in the dropins directory or in <eclipse>/plugins and <eclipse>/features, did you delete all directories/jar in <eclipse>/features, because if that plugin was packaged as a product, it did define in the product extension point a plugin_customization.ini which can indicate some perspective buttons.
If not, the only solution is to have a careful look at your workspace metadata, look for all recent file related to that plugin and remove them.
Make a copy of your workspace first though.
As an example of such a careful look at your workspace metadata", user900975 points out in his answer the <your workspace folder>/.metadata/.plugins/org.eclipse.ui.workbench/workbench.xml file, with <perspectives> element and <perspective> child elements that you can remove.
Note: Eightball mentions in his answer (upvoted) the possibility to list and delete a perspective.
Since he mentions "Some of them are un-removable. I don,t know why", my original answer above still stands.
Alexandros adds in the comments:
This helped me fix this, but in my case the file I had to edit while Eclipse was closed was:
.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi
I was suffering the same problem with a left-over perspective button for SVN repository Exploring. It wouldn't disappear using the close option. However it did disappear after selecting from Window -> Close All Perspectives.
Regards,
<your workspace folder>/.metadata/.plugins/org.eclipse.ui.workbench/workbench.xml contains a <perspectives> element with <perspective> child elements. You can delete <perspective> elements and they will no longer appear in the toolbar. Eclipse writes to this file when it exits so your changes will be overwritten if you don't quit Eclipse first.
If you installed a plugin, click Help ► Install new software, then click What's already installed? in the bottom right. Uninstall what you want, the perspective will be removed as well.
You could also try launching Eclipse with the -clean command line argument. This cleans out the Eclipse runtime cache, so it might fix your problem as well.
I had the same problem after installing a plugin. The answer is quite simple, if not obvious.
Open Window | Preferences
Click General node
Click Perspectives
Find the perspective in the list and then select Delete command on the right.
The list will refresh and your perspective is deleted.
I use Eclipse 3.3 in my daily work, and have also used Eclipse 3.2 extensively as well. In both versions, sometimes the Search options (Java Search, File Search, etc) in the menu get disabled, seemingly at random times. However, with Ctrl+H, I am able to access the search functionality. Does anyone know why this happens? Has it been fixed in Eclipse 3.4?
window > close all perspective works for me.
Using Eclipse 4.3(!) this happened to me after doing a case-sensitive search.
Window -> Close All Perspectives didn't fix it and neither did restarting Eclipse using -clean. While messing with the search box, I discovered that simply clicking to a previous search entry allowed me to edit it and search again! Clicking back to the case-sensitive search grayed the option out again.
So before you reset anything in your workspace, try pulling up an older search entry using the Down Arrow.
I think this answer is what you all need to solve the issue on all versions.
I am using RAD 8 and I have also faced this problem than I removed org.eclipse.search directory in (workspace currently using) workspace/metadata/plugins folder then restart the eclipse.
That's all.
I don't have an exact answer. I will recommend that you try to correlate the disablement with which perspective is active. Likewise, which view is active. I have been using 3.4 and not experienced this issue.
Darn! I have that problem too -- in Eclipse 3.4.2.
Seems to be related to Navigator and Project Explorer views:
- Switch to Debug perspective: Search menu items are there.
- Switch to Java or Java EE perspective: Search menu items still there.
- Click on a project in Navigator or Project Explorer: Search menu items all DISABLED.
(Curse! I use search in Selected Resources a lot! )-:
Hmmm... It may slso depend on the file type currently open in the editor. (Like Java vs xml.)
Still present in Eclipse 3.5.2 -- and for the first time really sticky.
I checked out the "close all opened files and open any other file afterwards" answer and that brought back the Search menu items. Additionally, if you were lucky and have the Search result view open, than indeed there is this little link "Open search dialog".
By the way, additionally lots of other project-related menu items seem to be greyed out also together with this, and they did not reanimate :-( But I did not really check out if these are only items for which it is useful and planned to be greyed out in this situation.
I'm using RAD 7.5.1 which runs on Eclipse 3.4 and I get this problem frustratingly often. It doesn't matter which perspective or view I'm in, or which editor I have open.
Restarting RAD usually clears it up, but because that's such a colossal pain, I found that you can get around it in the Search View, there is a link; "Start a search from the search dialog" which will bring up the search dialog.
This isn't a great workaround because the link only shows if you have no search history. To do another search, you'll have to clear your search history in the view.
A late comment for anyone getting bitten by this, but I found "eclipse -clean" fixed it => this does a cleanup of the workspace before starting
Thanks http://letsgetdugg.com/2009/04/19/recovering-a-corrupt-eclipse-workspace/ for the tip, after I guessed my workspace might be corrupt.
Before search, check you may choose scope in empty Working set. Most Search menu disables Search button when you choose it. And mine, too :)
window > close all perspectives worked for me too.
But if you are just looking for a text search in the project you could press Ctrl+Alt+G on a marked text
I couldn't get it to work even when restarting Eclipse.
Here's what worked for me: Closing all open files and opening a different file. The different file happened to be .java, but not sure if that had anything to do with it.
I get this problem from time to time.
In the past I've fixed by starting eclipse with the -clean option.
Once when that didn't work I created a new workspace.
I followed these instructions for those two solutions.
The clean option didn't work for me today and I found this thread because I didn't want to create a new workspace. The closing all files and reopening one file did work however.
I had this issue also in eclipse 3.6.2: Helios Service Release 1.
Closed all the editor windows, and the search has been enabled.
Switching to another perspective, then back, works quickly for me.
I've faced similar issue in Ctrl+H "File Search" tab. The "Search" and "Replace" button was grayed out (disabled). The solution is fill the "File name patterns" text box (for eg, *.py). May be this is by design!
I have this problem with MyEclipse 7 (eclipse 3.4) under Debian Lenny. Perspective doesn't seem to matter. I get around it with the shortcut Ctrl+H but I was hoping for a better way.
Just had this problem in Eclipse Neon 3. It is a very common problem in RAD. I could find using in the console, then switch back to the source and search. RAD would disable the find/search options per source file open. This is very frustrating.
I had this problem too. It appeared when I installed the m2eclipse plugin.
I had not found a solution, but you can use Ctrl+H shortcut instead.
And you can navigate between tabs with Ctrl+PgDown or Ctrl+PgUp keys.
I've uninstalled the following pluings and it worked.
Maven integration
PMD
eclipse checkstyle plugin
EclEmma (coverage)
I don't know which of those cause the problem. To uninstall a plugin: Help -> Software Updates...-> "Installed Software" tab.
