            Bug ID: 328568
           Summary: Don't blank window when reloading
    Classification: Unclassified
           Product: okular
           Version: 0.17.4
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: psychonaut at nothingisreal.com

I have Okular configured to watch files for changes (Configure->General->Reload
document on file change).  This makes it easy for me to edit a LaTeX document
in an editor and get an instant preview whenever I recompile the document to
PDF.  However, there is a slight annoyance: Okular blanks the window while it
is reloading the file.  This makes it harder for me to see the effect of my
changes.  (That is, sometimes I'll be reading the generated PDF in Okular and
spot a small error.  I make some changes in Emacs and recompile, and then
restore my gaze to the text in Okular to see the effect of my changes on that
section of the document.  Having the display suddenly blank for a second or two
while I'm doing makes me lose my position, and makes it harder for me to
compare the state of the document before and after the recompilation.)

Instead of blanking the window, please consider a less instrusive "loading"
notification, such as a message in the status bar, or a small throbber icon in
the corner of the window.  Then immediately display the document as soon as
it's loaded.  (If the document turns out to be broken, only then should the
window be blanked.)

Reproducible: Always

Steps to Reproduce:
1. Make sure Configure->General->Reload document on file change) is checked
2. Load a PDF document
3. Modify the PDF on disk
Actual Results:  
4. Okular detects the file has changed, and blanks the window while it reloads
the file

Expected Results:  
4. Okular should reload the file in the background and then immediately show it
without any interruption in the display

I haven't tried this with anything other than PDF files, though I suspect this
problem is not limited to the PDF back-end but is common to all file types.
