14 * Description: Platform agnostic Qt wrapper class for controlling display |
|
15 * power save mode. The power save mode gets actually activated |
|
16 * only on Symbian environment; in other environments the provided |
|
17 * functions do nothing. |
|
18 * The use of Symbian display power save API has been wrapped with |
|
19 * client-server pair because HbDeviceDialogs don't have enough |
|
20 * capabilities to call that API directly. |
