Veaceslav,

Look like this small class :

https://projects.kde.org/projects/extragear/graphics/kipi-plugins/repository/revisions/master/entry/common/libkipiplugins/tools/kprawthumbthread.h

is Qthread based and can be ported easily to ActionThreadbase.

KPRawThumbThread is a thread used to load RAW image thumbnail, into
ImageList widget or into ImageDialog file open dialog, in case of not
thumbnail extraction support exist into KIPI host application.

The goal is to load more than one thumbnail at the same time (if you
have more than one CPU avaialble), instead one by one as it done
currently.

To test class port, you have a "tests" subfolder into kipi-plugins and
a kipi test application which emule a very simplified kipi host
interface to run a plugin as a stand alone application. This
simplified KIPI interaface use KPRawThumbThread internally.

The right command line to use and test is this one :

./kipicmd -w -lkipiplugin_rawconverter -a"Batch RAW Converter..."

This will run RAW Batch Converter plugin. Add RAW files to convert in
the list and look if thumbnails are processed by group as expected...
