libkdcraw from KDE3 branch:
New integer and double input widget based on KDE components which provide a default value and a reset button, like we can found in pro-photograph programs like Aperture or Nikon Nx

New combo box widget based on KDE component which provide a default item and a reset button.
Adapt dcraw settings widget with these new objects.

Andi,
We need to use these widget into digiKam, especially into all image plugins.
I will use it in RAW import tool.
Just look my code to see how to use it.
