</table></div>
</div><div class="qmldoc"><p>This contains the current orientation of the screen, from the accelerometer (if any). On a desktop computer, this value typically does not change.</p>
<p>If <a href="qml-qtquick-window-screen.html#primaryOrientation-attached-prop">primaryOrientation</a> == orientation, it means that the screen automatically rotates all content which is displayed, depending on how you hold it. But if orientation changes while <a href="qml-qtquick-window-screen.html#primaryOrientation-attached-prop">primaryOrientation</a> does NOT change, then probably you are using a device which does not rotate its own display. In that case you may need to use <a href="qml-qtquick-item.html#rotation-prop">Item.rotation</a> or <a href="qml-qtquick-item.html#transform-prop">Item.transform</a> to rotate your content.</p>

<p>If you are designing an application which changes its layout depending on device orientation, you probably want to use primaryOrientation to determine the layout. That is because on a desktop computer, you can expect primaryOrientation to change when the user rotates the screen via the operating system's control panel, even if the computer does not contain an accelerometer. Likewise on most handheld computers which do have accelerometers, the operating system will rotate the whole screen automatically, so again you will see the primaryOrientation change.</p>
