[Digikam-devel] About retrieving tags from digikam and tags properties

[Gilles Caulier]

The first solution is to know the tags hierarchy for each item, using
tagspath properties :

http://lxr.kde.org/source/extragear/graphics/digikam/utilities/kipiiface/kipiimageinfo.cpp#133

... and create a delegate widget in your plugin to display it. Of
course, it can be complicated and long to do

Alternatively, a better way is  to delegate the tags view to kipi host
application..

libkipi has already a template class which must be re-implemented in
kipi host interface. This widget is dedicated to show album tree view
(physical and virtual) to a kipi plugin and to propose to user to set
a selection of an album. Look in HTML export or Flash Export plugins
for example. The dialog show a tab widget where you can select the
right albums to export.

Code is there :

http://lxr.kde.org/source/KDE/kdegraphics/libs/libkipi/libkipi/uploadwidget.h

and re-implemented here :

http://lxr.kde.org/source/extragear/graphics/digikam/utilities/kipiiface/kipiuploadwidget.h

and used there :

http://lxr.kde.org/source/extragear/graphics/kipi-plugins/flashexport/selectionpage.cpp#58

For your needs in GPSSync2 plugin, a similar template widget need to
be declared in libkipi, and re-implemented to Digikam::Kipiinterface.

What do you think about ?
