<h2 id="details">Detailed Description</h2>
<p>If the <a href="qml-qtquick-layouts-gridlayout.html">GridLayout</a> is resized, all items in the layout will be rearranged. It is similar to the widget-based QGridLayout. All visible children of the <a href="qml-qtquick-layouts-gridlayout.html">GridLayout</a> element will belong to the layout. If you want a layout with just one row or one column, you can use the <a href="qml-qtquick-layouts-rowlayout.html">RowLayout</a> or <a href="qml-qtquick-layouts-columnlayout.html">ColumnLayout</a>. These offer a bit more convenient API, and improve readability.</p>
<p>By default items will be arranged according to the <a href="qml-qtquick-layouts-gridlayout.html#flow-prop">flow</a> property. The default value of the <a href="qml-qtquick-layouts-gridlayout.html#flow-prop">flow</a> property is <code>GridLayout.LeftToRight</code>.</p>
<p>If the <a href="qml-qtquick-layouts-gridlayout.html#columns-prop">columns</a> property is specified, it will be treated as a maximum limit of how many columns the layout can have, before the auto-positioning wraps back to the beginning of the next row. The <a href="qml-qtquick-layouts-gridlayout.html#columns-prop">columns</a> property is only used when <a href="qml-qtquick-layouts-gridlayout.html#flow-prop">flow</a> is <code>GridLayout.LeftToRight</code>.</p>
<p class="centerAlign"><img src="images/gridlayout.png" alt="" /></p><pre class="cpp">
GridLayout {

columns: <span class="number">3</span>
Text { text: <span class="string">"Three"</span>; font<span class="operator">.</span>bold: <span class="keyword">true</span>; }

}
</pre>
<p>The <a href="qml-qtquick-layouts-gridlayout.html#rows-prop">rows</a> property works in a similar way, but items are auto-positioned vertically. The <a href="qml-qtquick-layouts-gridlayout.html#rows-prop">rows</a> property is only used when <a href="qml-qtquick-layouts-gridlayout.html#flow-prop">flow</a> is <code>GridLayout.TopToBottom</code>.</p>
<p>You can specify which cell you want an item to occupy by setting the <a href="qml-qtquick-layouts-layout.html#row-attached-prop">Layout.row</a> and <a href="qml-qtquick-layouts-layout.html#column-attached-prop">Layout.column</a> properties. You can also specify the row span or column span by setting the <a href="qml-qtquick-layouts-layout.html#rowSpan-attached-prop">Layout.rowSpan</a> or <a href="qml-qtquick-layouts-layout.html#columnSpan-attached-prop">Layout.columnSpan</a> properties.</p>
<p>Items in a <a href="qml-qtquick-layouts-gridlayout.html">GridLayout</a> support these attached properties:</p>
<ul>
<li><a href="qml-qtquick-layouts-layout.html#row-attached-prop">Layout.row</a></li>
