\wxheading{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.

\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf EVT\_ACTIVATE(func)}}{Process a wxEVT\_ACTIVATE event.}
\twocolitem{{\bf EVT\_ACTIVATE\_APP(func)}}{Process a wxEVT\_ACTIVATE\_APP event.}
\end{twocollist}%

\wxheading{Remarks}

A top-level window (a dialog or frame) receives an activate event when 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 inactivate resulting in all application frames being inactive. (Windows only)

Please note that usually you should call \helpref{event.Skip()}{wxeventskip} in
your handlers for these events as not doing so can result in strange effects,
especially on Mac platform.
