Description Oliver Sander 2017-04-27 21:34:56 UTC 
1) Open any pdf document
2) Press F6 to open the annotation toolbar
3) Press F5 to reload the document

Result: the annotation toolbar disappears again.

This is more annoying than it may seem, because you can also trigger a reload by saving the file onto itself.  Saving a file onto itself will touch the file; as a consequence, okular will (erroneously) think that it has changed, and reload it.  That is unfortunate, because saving while annotating is a frequent thing to do.

I had a look with the debugger.  Apparently, reloading involves first closing the document, and then opening it again (as can be seen from the backtrace I attach below).  Closing the document hides the annotation toolbar (that sounds reasonable, I guess), but then reopening does not switch it on again.  Any suggestions on how to fix this?

Here is the backtrace: I placed a breakpoint at pageviewutils.cpp:581, and then hit F6 & F5.

Comment 1 Oliver Sander 2017-05-06 08:42:47 UTC 
Before I can think further about this I need help with a basic decision:  Is it better to allow closing the document without hiding the toolbar, or is it better to make reload re-open the toolbar if it was open before?

I think this is more in line with what we do with other stuff.

I would expect the toolbar to remain shown when closing a document...
Comment 4 Jaime Torres 2018-11-17 16:13:59 UTC 
In okular 1.6.70, when the annotation toolbar is shown and the document is reloaded (or saved and reloaded), the annotation toolbar is still shown for that document (It has to be shown tab by tab for every document in a tabbed okular, like the other tools that are configured by document, not globally).
