<div class="descr">
<h2>Detailed Description</h2>
<p>The QItemSelectionRange class manages information about a range of selected items in a model.</p>
<p>A QItemSelectionRange contains information about a range of selected items in a model. A range of items is a contiguous array of model items, extending to cover a number of adjacent rows and columns with a common parent item; this can be visualized as a two-dimensional block of cells in a table. A selection range has a <a href="qitemselectionrange.html#top">top</a>(), <a href="qitemselectionrange.html#left">left</a>() a <a href="qitemselectionrange.html#bottom">bottom</a>(), <a href="qitemselectionrange.html#right">right</a>() and a <a href="qitemselectionrange.html#parent">parent</a>().</p>
<p>The QItemSelectionRange 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 model items contained in the selection range can be obtained using the <a href="qitemselectionrange.html#indexes">indexes</a>() function. Use <a href="qitemselectionmodel.html#selectedIndexes">QItemSelectionModel::selectedIndexes</a>() to get a list of all selected items for a view.</p>
<p>You can determine whether a given model item lies within a particular range by using the <a href="qitemselectionrange.html#contains">contains</a>() function. Ranges can also be compared using the overloaded operators for equality and inequality, and the <a href="qitemselectionrange.html#intersects">intersects</a>() function allows you to determine whether two ranges overlap.</p>
