data in views and delegates.</p>
<p>When editing data in an item view, editors are created and
displayed by a delegate. <a href="qitemdelegate.html">QItemDelegate</a>, which is the delegate by
default installed on Qt's item views, uses a QItemEditorFactory to
create editors for it. A default unique instance provided by
QItemEditorFactory is used by all item delegates. If you set a new
default factory with <a href="qitemeditorfactory.html#setDefaultFactory">setDefaultFactory</a>(),
the new factory will be used by existing and new delegates.</p>
<p>A factory keeps a collection of <a href="qitemeditorcreatorbase.html">QItemEditorCreatorBase</a> instances,
which are specialized editors that produce editors for one
particular <a href="qvariant.html">QVariant</a> data type (All Qt
models store their data in <a href="qvariant.html">QVariant</a>s).</p>
<a id="standard-editing-widgets" name="standard-editing-widgets" />
<h3>Standard Editing Widgets</h3>
<p>The standard factory implementation provides editors for a
variety of data types. These are created whenever a delegate needs
to provide an editor for data supplied by a model. The following
table shows the relationship between types and the standard editors
provided.</p>
<table class="generic">
