<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qheaderview.html">QHeaderView</a> class provides a header row or header column for item views.</p>
<p>A <a href="qheaderview.html">QHeaderView</a> 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 <code>QHeader</code> 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 <a href="qheaderview.html">QHeaderView</a> class is one of the <a href="model-view-programming.html#model-view-classes">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="../qtcore/qabstractitemmodel.html#headerData">QAbstractItemModel::headerData</a>() function. You can set the data by using <a href="../qtcore/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 name="moving-header-sections"></a>
<h3 id="moving-header-sections">Moving Header Sections</h3>
<p>A header can be fixed in place, or made movable with <a href="qheaderview.html#setSectionsMovable">setSectionsMovable</a>(). It can be made clickable with <a href="qheaderview.html#setSectionsClickable">setSectionsClickable</a>(), and has resizing behavior in accordance with <a href="qheaderview.html#setSectionResizeMode">setSectionResizeMode</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>().</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 name="appearance"></a>
<h3 id="appearance">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="../qtcore/qt.html#ItemDataRole-enum">ItemDataRole</a>s will have an effect on a <a href="qheaderview.html">QHeaderView</a>. If you need to draw other roles, you can subclass <a href="qheaderview.html">QHeaderView</a> and reimplement <a href="qheaderview.html#paintEvent">paintEvent()</a>. <a href="qheaderview.html">QHeaderView</a> respects the following item data roles, unless they are in conflict with the style (which can happen for styles that follow the desktop theme):</p>
<p><a href="../qtcore/qt.html#ItemDataRole-enum">TextAlignmentRole</a>, <a href="../qtcore/qt.html#ItemDataRole-enum">DisplayRole</a>, <a href="../qtcore/qt.html#ItemDataRole-enum">FontRole</a>, <a href="../qtcore/qt.html#ItemDataRole-enum">DecorationRole</a>, <a href="../qtcore/qt.html#ItemDataRole-enum">ForegroundRole</a>, and <a href="../qtcore/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></div>

<p>This property holds whether the first column can be moved by the user</p>
<p>This property controls whether the first column can be moved by the user. In a <a href="qtreeview.html">QTreeView</a>, the first column holds the tree structure and is therefore non-movable by default, even after <a href="qheaderview.html#setSectionsMovable">setSectionsMovable</a>(true).</p>
<p>It can be made movable again, for instance in the case of flat lists without a tree structure, by calling this method. In such a scenario, it is recommended to call <a href="qtreeview.html#rootIsDecorated-prop">QTreeView::setRootIsDecorated</a>(false) as well.</p>

<p>Sets how precise <a href="qheaderview.html">QHeaderView</a> should calculate the size when <a href="qheaderview.html#ResizeMode-enum">ResizeToContents</a> is used. A low value will provide a less accurate but fast auto resize while a higher value will provide a more accurate resize that however can be slow.</p>
<p>The number <i>precision</i> specifies how many sections that should be consider when calculating the preferred size.</p>
<p>The default value is 1000 meaning that a horizontal column with auto-resize will look at maximum 1000 rows on calculating when doing an auto resize.</p>
<p>Special value 0 means that it will look at only the visible area. Special value -1 will imply looking at all elements.</p>
<p>This value is used in <a href="qtableview.html#sizeHintForColumn">QTableView::sizeHintForColumn</a>(), <a href="qtableview.html#sizeHintForRow">QTableView::sizeHintForRow</a>() and <a href="qtreeview.html#sizeHintForColumn">QTreeView::sizeHintForColumn</a>().
