<p>The Graphics View Flow Layout example shows the use of a flow layout in a Graphics View widget.</p>
<p class="centerAlign"><img src="images/graphicsflowlayout-example.png" alt="" /></p><p>This example uses a Graphics View to display the widget, which is a more customizable approach than displaying the flow layout in the application window (See <a href="qtwidgets-layouts-flowlayout-example.html">Flow Layout Example</a>).</p>
