* 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.
