class provides a header row or header column for
item views.</p>
<p>A QHeaderView displays the headers used in item views such as
the <a href="qtableview.html">QTableView</a> and <a href="qtreeview.html">QTreeView</a> classes. It takes the place of Qt3's
<tt>QHeader</tt> class previously used for the same purpose, but
uses the Qt's model/view architecture for consistency with the item
view classes.</p>
<p>The QHeaderView class is one of the <a href="model-view.html">Model/View Classes</a> and is part of Qt's
<a href="model-view-programming.html">model/view framework</a>.</p>
<p>The header gets the data for each section from the model using
the <a href="qabstractitemmodel.html#headerData">QAbstractItemModel.headerData</a>()
function. You can set the data by using <a href="qabstractitemmodel.html#setHeaderData">QAbstractItemModel.setHeaderData</a>().</p>
<p>Each header has an <a href="qheaderview.html#orientation">orientation</a>() and a number of
sections, given by the <a href="qheaderview.html#count">count</a>()
function. A section refers to a part of the header - either a row
or a column, depending on the orientation.</p>
<p>Sections can be moved and resized using <a href="qheaderview.html#moveSection">moveSection</a>() and <a href="qheaderview.html#resizeSection">resizeSection</a>(); they can also
be hidden and shown with <a href="qheaderview.html#hideSection">hideSection</a>() and <a href="qheaderview.html#showSection">showSection</a>().</p>
<p>Each section of a header is described by a section ID, specified
by its section(), and can be located at a particular <a href="qheaderview.html#visualIndex">visualIndex</a>() in the header. A
section can have a sort indicator set with <a href="qheaderview.html#setSortIndicator">setSortIndicator</a>(); this
indicates whether the items in the associated item view will be
sorted in the order given by the section.</p>
<p>For a horizontal header the section is equivalent to a column in
the model, and for a vertical header the section is equivalent to a
row in the model.</p>
<a id="moving-header-sections" name="moving-header-sections" />
<h3>Moving Header Sections</h3>
<p>A header can be fixed in place, or made movable with <a href="qheaderview.html#setMovable">setMovable</a>(). It can be made
clickable with <a href="qheaderview.html#setClickable">setClickable</a>(), and has
resizing behavior in accordance with <a href="qheaderview.html#setResizeMode">setResizeMode</a>().</p>
<p><b>Note:</b> Double-clicking on a header to resize a section
only applies for visible rows.</p>
<p>A header will emit <a href="qheaderview.html#sectionMoved">sectionMoved</a>() if the user
moves a section, <a href="qheaderview.html#sectionResized">sectionResized</a>() if the user
resizes a section, and <a href="qheaderview.html#sectionClicked">sectionClicked</a>() as well as
<a href="qheaderview.html#sectionHandleDoubleClicked">sectionHandleDoubleClicked</a>()
in response to mouse clicks. A header will also emit <a href="qheaderview.html#sectionCountChanged">sectionCountChanged</a>()
and <a href="qheaderview.html#sectionAutoResize">sectionAutoResize</a>().</p>
<p>You can identify a section using the <a href="qheaderview.html#logicalIndex">logicalIndex</a>() and <a href="qheaderview.html#logicalIndexAt">logicalIndexAt</a>() functions,
or by its index position, using the <a href="qheaderview.html#visualIndex">visualIndex</a>() and <a href="qheaderview.html#visualIndexAt">visualIndexAt</a>() functions. The
visual index will change if a section is moved, but the logical
index will not change.</p>
<a id="appearance" name="appearance" />
<h3>Appearance</h3>
<p><a href="qtablewidget.html">QTableWidget</a> and <a href="qtableview.html">QTableView</a> create default headers. If you
want the headers to be visible, you can use <a href="qwidget.html#visible-prop">setVisible()</a>.</p>
<p>Not all <a href="qt.html#ItemDataRole-enum">ItemDataRole</a>s
will have an effect on a QHeaderView. If you need to draw other
roles, you can subclass QHeaderView and reimplement <a href="qheaderview.html#paintEvent">paintEvent()</a>. QHeaderView
respects the following item data roles: <a href="qt.html#ItemDataRole-enum">TextAlignmentRole</a>, <a href="qt.html#ItemDataRole-enum">DisplayRole</a>, <a href="qt.html#ItemDataRole-enum">FontRole</a>, <a href="qt.html#ItemDataRole-enum">DecorationRole</a>, <a href="qt.html#ItemDataRole-enum">ForegroundRole</a>, and <a href="qt.html#ItemDataRole-enum">BackgroundRole</a>.</p>
<p><b>Note:</b> Each header renders the data for each section
itself, and does not rely on a delegate. As a result, calling a
header's <a href="qabstractitemview.html#setItemDelegate">setItemDelegate</a>()
function will have no effect.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="ResizeMode-enum" />QHeaderView.ResizeMode</h3><p>The resize mode specifies the behavior of the header sections.
It can be set on the entire header view or on individual sections
using <a href="qheaderview.html#setResizeMode">setResizeMode</a>().</p>
