I have two Perspectives and two editor part each.
When preperspective changed to postperspective , the editor opend is closed . then changed again to preperspective , no editor can be recovered.
How can I rememver the Editor Opend , even when changing perspective occured. and can I recover it again?
This behavior actually contradicts to the Eclipse UI metaphor where editors are shared between perspectives.
So you have to implement your own persistent storage for perpective:editors map. Also look at http://help.eclipse.org/help33/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/debug/ui/sourcelookup/CommonSourceNotFoundEditorInput.html#getPersistable()

I'm using Eclipse Neon and am observing annoying behavior that I didn't have with Mars: the list of files that are open in the editor frames changes when I move from C-perspective to debug-perspective. I lose track between perspectives of which files are open where (I use multiple editor frames). Is there a way to disable that specific behavior? I want to keep the behavior of eclipse automatically changing between perspectives when I run the debugger, I just don't want the editor tabs reshuffled in the process.
C/C++ Perspective -- I have a bunch of files open, represented by editor tabs
Debug Perspective -- note editors now show only two open tabs, and the ordering is different.
EDIT: I discovered this only happens when I use two separate editor frames (i.e., each frame is independently minimizable). When I have two editors inside a single minimizable frame, the tab order is preserved between perspectives.
Like in the topic - is there any default way or any plugin that lets you have multiple 'Compare' windows open and active at the same time? I find it very frustrating that while doing changes to few files at the same time, I can't have active 'Compare' window for each of them, to see my changes/original code.
I would use Window -> New Window, rerun Team -> Show History and then compare another file.
A compare window in Eclipse is placed inside a normal editor tab.
You can have several editor tabs, including compare windows, visible at the same time. To do this just drag the editor tab (the one on the top with the editor name) to somewhere inside the editor area. The editor area will get split in two, each one displaying one editor.
This works with more than two editors also.
If you find that you need more space for the compare windows because other views take up much space you can maximize the editor area by pressing Ctrl+M while the editor area has focus.
Example:
Go to preferences -> team -> General Team Preferences. For me, the "Reuse open compare editors when opening comparisons" was already checked by default. I unchecked that and now I can have multiple file comparison windows open! (I'm using Eclipse Oxygen.3a -- 4.7.3a)
I have noticed that qtCreator handles the auto-completion much better than eclipse.
For example, if I have a line that says object.firstItem() and put my cursor between . and f, and then delete the first word (thus becoming object.|item()) and then press ctrl+space and choose secondItem(), qtCreator guesses object.secondItem();, whereas eclipse chooses object.firstItem()Item().
There could well be other features that are present in qtCreator, too, but not in eclipse, though it's the only one I really noticed. But why not share all good ideas since they all are open source ? I would be interested in all good features of qtCreator and eclipse combined.
Is there a way to have such a behaviour in eclipse too, through configuration or through a plugin ?
This feature is supported by Eclipse, too. (Or more specifically, the Eclipse Java Development Tools.)
Just hold down the ctrl key when selecting the item from the list of proposed completions to toggle between inserting and overwriting completion mode.
To change the default behaviour, go to Preferences -> Java -> Editor -> Content Assist and change the top-most radio button from "Completion inserts" to "Completion overwrites".
I have eclipse Juno. I'm not sure how, but my editor in eclipse is now "invisible". By invisible i mean, the editor pane is not in the visible window. I'm not a novice in eclipse and i know you can minimize the editors or maximize a different panel - but this isn't the case. There isn't even a minimize/maximize button on this empty space where the editor should be.
However, the title bar shows the current file that is opened (but in the invisible editor and hence invisible). and my outline sidebar shows the file's outline.
I think this might have happened when splitting editor panes (which i do a lot, love the side by side comparison), and also switching the perspective.
Any ideas on how i can get the editor back in the visible window?
Above is a screenshot of how it looks. At the time of the screen shot i had just recently clicked a file to open it, and it seems to have opened in the invisible editor.
I've tried all given solutions and none of them solved the problem.
Only using Window->New Window gave me a new fixed eclipse window.
Try Window > Reset Perspective to get things back to normal.
I minimized sharedArea and after restore it was empty. Editors worked well (open, close, save etc.) but i could not see them. Closing all perspectives helped.
This happens to me sometimes when I try to split an editor group by dragging an editor tab. The only solution that worked for me was to close every single perspective in the application toolbar, then Window -> New Window.
I've had this happen occasionally when splitting panes. Restarting Eclipse didn't work for me, nor did resetting the perspective.
The solution I stumbled upon was to give the editor area focus (by clicking in the area where it should be, I suppose) and close files in the invisible editor with Ctrl+W until the editor reappears. You may notice the window title changes to follow the file in the hidden editor.
I had the same problem and simply stopping/restarting Eclipse fixed it.
I have the fix, when neither resetting the perspective or restarting eclipse helps:
At the bottom of the File Menu, there is your recent file name that you are trying to get back. Click on that and it should return.
Start eclipse with:
eclipse.exe -repair
I feel slightly like n00b encountering windows for the first time, but I have lost the editor window in Eclipse. I had dragged one of two tabs to one side such that I could view the two files side by side and it disappeared. Foolishly, I then dragged the remaining tab to the same position and found that it also disappeared.
When I select 'Windows' > 'Navigation' > 'Next editor' I can see that both files are still open. I have tried opening other files, and although they do open they are similarly invisible. I tried resetting the perspective, but the editor was left absent. I'm running out of ideas, so any contributions would be highly welcome! I'm using a mac by the way.
Perspective reset or window->new editor did not work for me. What worked though was to create a new window with Window->New Window, and then close the first one with editor hidden. Hope this help.
Just so this case be changed to 'answered':
I ended up using cmd-W to close the editors one by one, then was able to open a new editor. I still don't understand what caused the problem, but at least it is solved now. Many thanks for the suggestions though!
Pressing the F12 key normally focuses the Editor only if the Editor is not minimized.
Window -> New Editor is also disabled once the Editor view is minimized.
What's definitely going to work is resetting the perspective by doing Window -> Reset Perspective. That should bring the editor back into view.
Take a look at this screencast which shows how to do this.
They might have been in a separate window. Try right clicking on the Eclipse icon on your dock and see if the editors are there. If yes, drag them to your IDE.
I got the same problem today. I solved it just by Window > Reset perspective...
I have lost the editor too doing drag & drop. I try all here, and finally I used Window > New Widow and the second one comes with editor.
