model.</p>
<p>A QPersistentModelIndex is a model index that can be stored by
an application, and later used to access information in a model.
Unlike the <a href="qmodelindex.html">QModelIndex</a> class, it is
safe to store a QPersistentModelIndex since the model will ensure
that references to items will continue to be valid as long as they
can be accessed by the model.</p>
<p>It is good practice to check that persistent model indexes are
valid before using them.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QPersistentModelIndex" />QPersistentModelIndex.__init__ (<i>self</i>)</h3><p>Creates a new <a href="qpersistentmodelindex.html">QPersistentModelIndex</a> that is a
copy of the model <i>index</i>.</p>
<h3 class="fn"><a name="QPersistentModelIndex-2" />QPersistentModelIndex.__init__ (<i>self</i>, <a href="qmodelindex.html">QModelIndex</a> <i>index</i>)</h3><h3 class="fn"><a name="QPersistentModelIndex-3" />QPersistentModelIndex.__init__ (<i>self</i>, <a href="qpersistentmodelindex.html">QPersistentModelIndex</a> <i>other</i>)</h3><p>Creates a new <a href="qpersistentmodelindex.html">QPersistentModelIndex</a> that is a
copy of the <i>other</i> persistent model index.</p>
<h3 class="fn"><a name="child" /><a href="qmodelindex.html">QModelIndex</a> QPersistentModelIndex.child (<i>self</i>, int <i>row</i>, int <i>column</i>)</h3><p>Returns the child of the model index that is stored in the given
<i>row</i> and <i>column</i>.</p>
<p><b>See also</b> <a href="qpersistentmodelindex.html#parent">parent</a>() and <a href="qpersistentmodelindex.html#sibling">sibling</a>().</p>
<h3 class="fn"><a name="column" />int QPersistentModelIndex.column (<i>self</i>)</h3><p>Returns the column this persistent model index refers to.</p>
<h3 class="fn"><a name="data" />QVariant QPersistentModelIndex.data (<i>self</i>, int <i>role</i> = Qt.DisplayRole)</h3><p>Returns the data for the given <i>role</i> for the item referred
to by the index.</p>
<p><b>See also</b> <a href="qt.html#ItemDataRole-enum">Qt.ItemDataRole</a> and <a href="qabstractitemmodel.html#setData">QAbstractItemModel.setData</a>().</p>
<h3 class="fn"><a name="flags" /><a href="qt-itemflags.html">Qt.ItemFlags</a> QPersistentModelIndex.flags (<i>self</i>)</h3><p>Returns the flags for the item referred to by the index.</p>
<p>This function was introduced in Qt 4.2.</p>
<h3 class="fn"><a name="isValid" />bool QPersistentModelIndex.isValid (<i>self</i>)</h3><p>Returns true if this persistent model index is valid; otherwise
returns false.</p>
<p>A valid index belongs to a model, and has non-negative row and
column numbers.</p>

<h3 class="fn"><a name="parent" /><a href="qmodelindex.html">QModelIndex</a> QPersistentModelIndex.parent (<i>self</i>)</h3><p>Returns the parent <a href="qmodelindex.html">QModelIndex</a>
for this persistent index, or an invalid <a href="qmodelindex.html">QModelIndex</a> if it has no parent.</p>
<p><b>See also</b> <a href="qpersistentmodelindex.html#child">child</a>(), <a href="qpersistentmodelindex.html#sibling">sibling</a>(), and <a href="qpersistentmodelindex.html#model">model</a>().</p>

<h3 class="fn"><a name="sibling" /><a href="qmodelindex.html">QModelIndex</a> QPersistentModelIndex.sibling (<i>self</i>, int <i>row</i>, int <i>column</i>)</h3><p>Returns the sibling at <i>row</i> and <i>column</i> or an
invalid <a href="qmodelindex.html">QModelIndex</a> if there is no
sibling at this position.</p>
