\section{\class{wxNotebookEvent}}\label{wxnotebookevent} This class represents the events generated by a notebook control. \wxheading{Derived from} \helpref{wxCommandEvent}{wxcommandevent}\\ \helpref{wxEvent}{wxevent}\\ \helpref{wxEvtHandler}{wxevthandler}\\ \helpref{wxObject}{wxobject} \wxheading{Event table macros} To process a notebook event, use these event handler macros to direct input to member functions that take a wxNotebookEvent argument. \twocolwidtha{7cm} \begin{twocollist}\itemsep=0pt \twocolitem{{\bf EVT\_NOTEBOOK_PAGE_CHANGED(id, func)}}{The page selection was changed.
