Inheritance diagram for wxPowerEvent:

Detailed Description

The power events are generated when the system power state changes, e.g.

the system is suspended, hibernated, plugged into or unplugged from the wall socket and so on. wxPowerEvents are emitted by wxWindows.

Notice that currently only suspend and resume events are generated and only under MS Windows platform. To avoid the need to change the code using this event later when these events are implemented on the other platforms please use the test ifdef wxHAS_POWER_EVENTS instead of directly testing for the platform in your code: this symbol will be defined for all platforms supporting the power events.

Events using this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:
