Detailed Description

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").; 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, without 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.

void KCategorizedView::setGridSizeOwn ( const QSize & size )

Warning: note that setGridSize is not virtual in the base class (QListView), so if you are calling to this method, make sure you have a KCategorizedView pointer around. This means that something like:
QListView *lv = new KCategorizedView();

lv->setGridSize(mySize);

will not call to the expected setGridSize method. Instead do something like this:

QListView *lv;
...
KCategorizedView *cv = qobject_cast<KCategorizedView*>(lv);
if (cv) {
    cv->setGridSizeOwn(mySize);
} else {
    lv->setGridSize(mySize);
}

Note: this method will call to QListView::setGridSize among other operations.
