<h2 id="details">Detailed Description</h2>
<p>This item needs to be a descendant of a <a href="qml-qtwayland-compositor-waylandquickitem.html">WaylandQuickItem</a> or a derivative, (i.e. <a href="qml-qtwayland-compositor-shellsurfaceitem.html">ShellSurfaceItem</a> or similar)</p>
<p>The Surface of the parent <a href="qml-qtwayland-compositor-waylandquickitem.html">WaylandQuickItem</a> will be drawn in a hardware specific way instead of the regular way using the QtQuick scene graph. On some platforms, the <a href="qml-qtwayland-compositor-waylandquickitem.html">WaylandQuickItem</a>'s current buffer and the scene graph can be blended in a separate step. This makes it possible for clients to update continuously without triggering a full redraw of the compositor scene graph for each frame.</p>
<p>The preferred hardware layer integration may be overridden by setting the QT_WAYLAND_HARDWARE_LAYER_INTEGRATION environment variable.</p>

<p>Layers with a level below 0 are drawn beneath the compositor scene graph, if supported by the hardware layer integration.</p>
