Description Eugenio Yime 2008-08-26 12:28:12 UTC
Version:            (using KDE 4.1.0)
OS:                Linux
Installed from:    SuSE RPMs

Sometimes a pdf contains sentences like this:

In equation XXX ....
In Section XXX ....

where XXX refers to a item in another page, which is not always the next or before page, so I think a good way to around this can be a 'split' feature like dolphin.

In this way the left window can display the actual page and the right window will display the page with the item.

Thanks.

I need this! :)

This bug is related to the following bugs:

Bug 155515: Switch to tabbed interface
This bug requests for Okular to have tabs like Dolphin.

Bug 174958: Side by Side mode
This bug requests a special mode for the split view feature in which all non-critical vertical elements (elements that take up horizontal width) are removed to allow for two side-by-side documents to be shown at the maximum zoom level possible. It is not a dupe of this bug as it suggests extreme measures, such as trimming the page margins and removing interface elements.

No, that bug is not related to this at all.
You can perfectly have a split view in Okular for the same document with the current SDI (single document interface), and viceversa (multiple documents but no split view at all).

I suppose that you are right.
Comment 8 mps 2009-03-12 16:02:59 UTC
Absolutely, this would be great. Personally I'd like the split to be top-bottom so you have have the references section of a document in the bottom pane and the main text in the top pane.

As a quick interim solution, could we have 

View -> Open in new Window

like in Kate? This would quickly open another Okular instance on the same document at the same page. One can then arrange the windows underneath each other or side by side.

Comment 12 Jonas 2011-10-13 16:25:53 UTC
I agree with #8, top-down splitting would be very useful to view references. On a large screen, you can still have the full page on top, and a small area for references below.

Note that bug #174958, marked as a dupe of this one, requests the ability to open two different PDF files in separate panes, not necessarily the same PDF in both panes.

That's totally what I would vote for

Comment 16 tprotopopescu 2013-12-14 17:07:51 UTC
This would be a really useful feature. I especially agree with #8 and #12, top-bottom splitting would be really handy to be able to check references and endnotes.
Comment 17 schmidt.simon 2014-02-08 13:45:11 UTC
This is already possible in konqueror, open a pdf and then Window -> Split View Left/Right. Would be nice if okular had this too as it tends to use less memory.

Also wish that annotation can be synced between both views.
Comment 20 Andras Soltesz 2016-08-17 08:19:38 UTC
I also think this would be an important feature. Now I can only do this with 2 separate Okular windows which is not as easy to handle than a well implemented split feature.

Comment 25 Musikolo 2018-02-16 03:22:57 UTC
Is there any chance this feature gets eventually implemented? 

I'm asking because it was originally requested over 9 years ago, and I see nothing that suggests it's coming anytime in the future.

Thank you and long live Okular!
Comment 26 Nate Graham 2018-02-16 03:25:04 UTC
There's always a chance! But this is a mostly volunteer project, and it needs a developer to do the work. You, maybe? ;)

Comment 27 Musikolo 2018-02-16 03:59:06 UTC
Sounds fair! Can you please pass me a link to the source code?

This said, I had no intention of pushing, because as you said, open source software is all good will... ;-)
Comment 28 Nate Graham 2018-02-16 04:23:24 UTC
Feel free to read the documentation I linked to, which  will help you find what you're looking for!
Comment 29 Germano Massullo 2018-02-16 09:02:25 UTC
Does KDE allow a bounty program?
Comment 30 Nate Graham 2018-02-18 05:28:31 UTC
It's not in our power to allow or dis-allow anything. Feel free to post a bounty if you'd like.

I want to indicate that workaround with konqueror (as noted in comment 17) still works.
