Also, the model will need to be + * flagged as categorized with KCategorizedSortFilterProxyModel::setCategorizedModel(true). + * + * The way it works (if categorization enabled): + * + * - When sorting, it does more things than QListView does. It will ask the model for the + * special role CategorySortRole (@see KCategorizedSortFilterProxyModel). This can return + * a QString or an int in order to tell the view the order of categories. In this sense, for + * instance, if we are sorting by name ascending, "A" would be before than "B". If we are + * sorting by size ascending, 512 bytes would be before 1024 bytes. This way categories are + * also sorted. + * + * - When the view has to paint, it will ask the model with the role CategoryDisplayRole + * (@see KCategorizedSortFilterProxyModel). It will for instance return "F" for "foo.pdf" if + * we are sorting by name ascending, or "Small" if a certain item has 100 bytes, for example. + * + * For drawing categories, KCategoryDrawer will be used. You can inherit this class to do your own + * drawing. + * + * @note All examples cited before talk about filesystems and such, but have present that this + * is a completely generic class, and it can be used for whatever your purpose is.
