\section{\class{wxActivateEvent}}\label{wxactivateevent} An activate event is sent when a window or application is being activated or deactivated. \wxheading{Derived from} \helpref{wxEvent}{wxevent}\\ \helpref{wxObject}{wxobject} \wxheading{Include files} \wxheading{Library} \helpref{wxCore}{librarieslist} \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. \twocolwidtha{7cm} \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.} \twocolitem{{\bf 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.} \end{twocollist}% \wxheading{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 \helpref{event.Skip()}{wxeventskip} in your handlers for these events as not doing so can result in strange effects. \wxheading{See also} \helpref{Event handling overview}{eventhandlingoverview},\rtfsp \helpref{wxApp::IsActive}{wxappisactive} \latexignore{\rtfignore{\wxheading{Members}}} \membersection{wxActivateEvent::wxActivateEvent}\label{wxactivateeventctor} \func{}{wxActivateEvent}{\param{WXTYPE }{eventType = 0}, \param{bool}{ active = true}, \param{int }{id = 0}} Constructor. \membersection{wxActivateEvent::GetActive}\label{wxactivateeventgetactive} \constfunc{bool}{GetActive}{\void} Returns true if the application or window is being activated, false otherwise.
