29 | The power events are generated when the system power state changes, e.g. the |
30 | system is suspended, hibernated, plugged into or unplugged from the wall socket | |
3051a44a | 31 | and so on. wxPowerEvents are emitted by wxWindows. |
7c913512 | 32 | |

33 | Notice that currently only suspend and resume events are generated and only |
34 | under MS Windows platform. To avoid the need to change the code using this | |
b1b95a65 FM |
35 | event later when these events are implemented on the other platforms please |
36 | use the test <tt>ifdef wxHAS_POWER_EVENTS</tt> instead of directly testing for | |
23324ae1 FM |
37 | the platform in your code: this symbol will be defined for all platforms |
38 | supporting the power events. | |

42 | System is about to be suspended, this event can be vetoed to prevent |
43 | suspend from taking place. | |

45 | System is about to suspend: normally the application should quickly |
46 | (i.e. without user intervention) close all the open files and network | |
47 | connections here, possibly remembering them to reopen them later when | |
48 | the system is resumed. | |
3051a44a | 49 | @event{EVT_POWER_SUSPEND_CANCEL(func)} |
b1b95a65 | 50 | System suspension was cancelled because some application vetoed it. |
3051a44a | 51 | @event{EVT_POWER_RESUME(func)} |
b1b95a65 FM |
52 | System resumed from suspend: normally the application should restore |
53 | the state in which it had been before the suspension. | |
