Summary: Resizing the main window changes the currently displayed
page of a pdf document
Product: okular
Version: 0.6.90
Platform: Ubuntu Packages
OS/Version: Linux
Status: NEW
Severity: normal
Priority: NOR
Component: general
AssignedTo: okular-devel kde org
ReportedBy: andersin freenet de
Version: 0.6.90 (using KDE 4.0.98)
Installed from: Ubuntu Packages
OS: Linux
When resizing the main window of a pdf file, okular changes the currently
displayed page, increasing it when the window gets smaller and decreasing it
when the window gets bigger.
I have used several pdfs to test this, but will explain this bug with
http://stderr.org/doc/pbuilder/pbuilder-doc.pdf which contains 28 pages. My
view mode is continuous with single pages. The zoom is set to "Fit Page" and
the content side bar is open.
1. Open the document.
2. Maximize the okular window (or at least make it very large)
3. Scroll down to a page close to the end, say 25
4. Restore the okular window (or make it significantly smaller)
- This causes okular to now display page 28, the last page in the document
5. Maximize the okular window again (or increase the size again)
- This causes okular to now display page 16 (this is somewhat dependent on the
difference between maximized size and initial size if the non-maximized window
is only slightly smaller than my screen, okular jumps to page 26.
Note that this effect only occurs with high page numbers, it will not work on
the first pages. Unfortunately I could not determine the exact cut-off.
My hunch is that it is related to the size of the scroll bar in the smaller
window, such that okular tries to place the scroller at the same pixel offset
that it was at before and thus reaches a different page. I have not looked at
the code though and this is purely speculation.
