Initial version of the Star Picker Widget.
A very simple to use widget: StarWidget *stars = new StarWidget( windowParent); stars->setMaximumStars(10); stars->setCurrentStars( rand()%10); stars->show(); connect(stars, SIGNAL(valueChanged(int)), someObj, SLOT(starsChangedValue(int))); It currently uses a 'star.svg' file on the same folder as the binary.
