|
|
* DESCRIPTION:
|
|
*
|
|
* Implements the battery meter of the PowerCfg or SysTray battery
|
|
* meter windows. The battery meter has two display modes, single and
|
|
* multi-battery. In single mode, a representation of the total of all battery
|
|
* capacity in a system is displayed. In multi-battery mode, battery
|
|
* information is displayed for each individual battery as well as the total.
|
|
*
|
|
* The battery meter parent window receives notification from USER when
|
|
* any battery status has changed through the WM_POWERBROADCAST,
|
|
* PBT_APMPOWERSTATUSCHANGE message.
|
|
*
|
|
* ??? We need to add perfmon support: Create and maintain keys/values
|
|
* under HKEY_PERFORMANCE_DATA.
