#include <QListView>
#include <groupview_config.h>
class KCategoryDrawer;
/**
* @short Item view for listing items in a categorized fashion optionally
*
* KCategorizedView basically has the same functionality as QListView, only that it also lets you
* layout items in a way that they are categorized visually.
*
* For it to work you will need to set a KCategorizedSortFilterProxyModel and a KCategoryDrawer
* with methods setModel() and setCategoryDrawer() respectively. 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. For
* instance when talking about animals, you can separate them by "Mammal" and "Oviparous". In
* this very case, for example, the CategorySortRole and the CategoryDisplayRole could be the
* same ("Mammal" and "Oviparous").
*
* @note There is a really performance boost if CategorySortRole returns an int instead of a QString.
* Have present that this role is asked (n * log n) times when sorting and compared. Comparing
* ints is always faster than comparing strings, whithout mattering how fast the string
* comparison is. Consider thinking of a way of returning ints instead of QStrings if your
* model can contain a high number of items.
*
* @warning Note that for really drawing items in blocks you will need some things to be done:
* - The model set to this view has to be (or inherit if you want to do special stuff
* in it) KCategorizedSortFilterProxyModel.
* - This model needs to be set setCategorizedModel to true.
* - Set a category drawer by calling setCategoryDrawer.
*
* @see KCategorizedSortFilterProxyModel, KCategoryDrawer
