4 | or deactivated. | |

20 | ||
21 | To process an activate event, use these event handler macros to direct input to a member | |
22 | function that takes a wxActivateEvent argument. | |

29 | This event applies to wxApp only, and only on Windows SmartPhone and PocketPC. It is generated when the | |
30 | system is low on memory; the application should free up as much memory as possible, and restore | |
31 | full working state when it receives a wxEVT\_ACTIVATE or wxEVT\_ACTIVATE\_APP event.} | |

34 | \wxheading{Remarks} | |
35 | ||
36 | A top-level window (a dialog or frame) receives an activate event when it is | |
37 | being activated or deactivated. This is indicated visually by the title | |
38 | bar changing colour, and a subwindow gaining the keyboard focus. | |
39 | ||
40 | An application is activated or deactivated when one of its frames becomes activated, | |
41 | or a frame becomes inactivated resulting in all application frames being inactive. | |
42 | ||
43 | Please note that usually you should call \helpref{event.Skip()}{wxeventskip} in | |
44 | your handlers for these events as not doing so can result in strange effects. | |
