This is indicated visually by the title 34bar changing colour, and a subwindow gaining the keyboard focus. 35 36An application is activated or deactivated when one of its frames becomes activated, 37or a frame becomes inactivated resulting in all application frames being inactive. 38 39Please note that usually you should call \helpref{event.Skip()}{wxeventskip} in 40your handlers for these events as not doing so can result in strange effects. 41 42\wxheading{See also} 43 44\helpref{Event handling overview}{eventhandlingoverview},\rtfsp 45\helpref{wxApp::IsActive}{wxappisactive} 46 47\latexignore{\rtfignore{\wxheading{Members}}} 48 49\membersection{wxActivateEvent::wxActivateEvent}\label{wxactivateeventctor} 50 51\func{}{wxActivateEvent}{\param{WXTYPE }{eventType = 0}, \param{bool}{ active = true}, \param{int }{id = 0}} 52 53Constructor. 54 55\membersection{wxActivateEvent::GetActive}\label{wxactivateeventgetactive} 56 57\constfunc{bool}{GetActive}{\void} 58 59Returns true if the application or window is being activated, false otherwise. 60 61
