<h1>KCategorizedView Class Reference</h1>
<code>from PyKDE4.kdeui import *</code>
<p>
Inherits: QListView → QAbstractItemView → QAbstractScrollArea → QFrame → QWidget → QObject<br />
<h2>Detailed Description</h2>
<p>Item view for listing items in a categorized fashion optionally
</p>
<p>
KCategorizedView basically has the same functionality as QListView, only that it also lets you
layout items in a way that they are categorized visually.
</p>
<p>
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).
</p>
<p>
The way it works (if categorization enabled):
</p>
<p>
- 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.
</p>
<p>
- 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.
</p>
<p>
For drawing categories, KCategoryDrawer will be used. You can inherit this class to do your own
drawing.
</p>
<p>
<dl class="note" compact><dt><b>Note:</b></dt><dd> 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").
</dd></dl> </p>
<p>
<dl class="note" compact><dt><b>Note:</b></dt><dd> 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.
</dd></dl> </p>
<p>
