           Summary: conflicting directions of mouse scroll when zooming
           Product: digikam
           Version: 0.9.4-svn
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: Preview
        AssignedTo: digikam-devel kde org
        ReportedBy: mikmach wp pl


Version:           0.9.4-svn (using Devel)
Installed from:    Compiled sources
Compiler:          gcc4.3
OS:                Linux

In preview mode there are two ways to zoom with mouse wheel:

- hover mouse over slider and scroll wheel
- use Ctrl+mouse wheel over image

Both are good, logical, common actions for many applications.

Problem is: to zoom in (or out) in both ways you have to scroll wheel in opposite directions. To zoom in while hovering over slider you have to scroll mouse wheel "in" toward yourself. But to perform the same action with Ctrl you have to scroll "out" - in opposite direction. There should be consistency in both actions. To keep consistency with other KDE application behavior of hovering action should be changed.

Gilles, is digikam/libs/widgets/common/statuszoombar.cpp
the right place to modify?

I think for 0.10, this can be easily done
by defining the slider using
http://doc.trolltech.com/4.3/qabstractslider.html#invertedControls-prop

"""If this property is false, scrolling the mouse wheel "up" and using
keys like page up will increase the slider's value towards its
maximum. Otherwise pressing page up will move value towards the
slider's minimum."""

For 0.9.x: is it necessary to overwrite wheelEvent?

Note that the KDE4PORT will be much simpler: Adding
  d->zoomSlider->setInvertedControls(true);
should do the job.
