For the stars on the dive table I had to rework a bit my StarRating widget, because it used a pixmap for each widget that were created. Not it uses only 2 pixmaps: the active and inactive ones. A new file was created named modeldelegates(h, cpp) that should hold all delegates of the models. For the GTK / C folks, a 'Delegate' ia s way to bypass the default behavior of the view that's displaying the data. I also added the code to display the stars if no delegate is set ( good for debugging. ) Signed-off-by: Tomaz Canabrava <tcanabrava@kde.org>
