<!-- $$$QGalleryQueryModel-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QGalleryQueryModel class provides a model for the results of a gallery query.</p>
<p>The meta-data that should be queried by a QGalleryQueryModel is specified by adding columns to the model, each column has a set of <a href="qgalleryquerymodel.html#roleProperties">roleProperties</a>() which map item data roles to gallery properties. After the model query has been executed the values of the properties requested for each column can be addressed using the roles they were mapped to.</p>
<p>The <a href="qgalleryquerymodel.html#rootType-prop">rootType</a> property identifies the type of gallery item the request should return, if the root type has derivative types (i.e. an audio file is just a special case of a regular file) these will also be included in the result set.</p>
<p>The <a href="qgalleryquerymodel.html#rootItem-prop">rootItem</a> property takes the ID of an item the query should only return the children of. Depending on the <a href="qgalleryquerymodel.html#scope-prop">scope</a> of the query this may be {AllDescendents}{all descendents} or just the {DirectDescendents} {direct descendents} of the root item.</p>
<p>The results of a query can be further limited by setting a <a href="qgalleryquerymodel.html#filter-prop">filter</a> on the model. The model will evaluate the <a href="qgalleryfilter.html">QGalleryFilter</a> and only include items with meta-data matching the expression.</p>
<p>The order the results are returned in can be specified in the <a href="qgalleryquerymodel.html#sortPropertyNames-prop">sortPropertyNames</a> property which takes an ordered list of property names. By default properties are sorted in ascending order, but this can be specified explicitly be prefixing the property name with a '+' character for ascending order and a '-' character for descending order.</p>
<p>If the <a href="qgalleryquerymodel.html#autoUpdate-prop">autoUpdate</a> property is true when the query is executed it will enter an <a href="qgalleryabstractrequest.html#State-enum">Idle</a> state on finishing and will refresh the queried information if the items matching the query change. If the gallery can't provide updates it will instead go immediately to the <a href="qgalleryabstractrequest.html#State-enum">Finished</a> state. Automatic updates can be canceled by calling <a href="qgalleryquerymodel.html#cancel">cancel</a>() on a idle model.</p>
