Event table macros

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

EVT_ACTIVATE(func) | Process a wxEVT_ACTIVATE event.
EVT_ACTIVATE_APP(func) | Process a wxEVT_ACTIVATE_APP event.
EVT_HIBERNATE(func) | Process a hibernate event, supplying the member function. This event applies to wxApp only, and only on Windows SmartPhone and PocketPC. It is generated when the system is low on memory; the application should free up as much memory as possible, and restore full working state when it receives a wxEVT_ACTIVATE or wxEVT_ACTIVATE_APP event.

Remarks

A top-level window (a dialog or frame) receives an activate event when it is being activated or deactivated. This is indicated visually by the title bar changing colour, and a subwindow gaining the keyboard focus.

An application is activated or deactivated when one of its frames becomes activated, or a frame becomes inactivated resulting in all application frames being inactive.

Please note that usually you should call event.Skip() in your handlers for these events as not doing so can result in strange effects.
