39
40\func{}{wxCloseEvent}{\param{WXTYPE}{ commandEventType = 0}, \param{int}{ id = 0}}
41
42Constructor.
43
44\membersection{wxCloseEvent::CanVeto}\label{wxcloseeventcanveto}
45
46\func{bool}{CanVeto}{\void}
47
48Returns TRUE if you can veto a system shutdown or a window close event.
49Vetoing a window close event is not possible if the calling code wishes to
50force the application to exit, and so this function must be called to check this.
51
52\membersection{wxCloseEvent::GetLoggingOff}\label{wxcloseeventgetloggingoff}
53
54\constfunc{bool}{GetLoggingOff}{\void}
55
56Returns TRUE if the user is logging off.
57
58\membersection{wxCloseEvent::GetSessionEnding}\label{wxcloseeventgetsessionending}
59
60\constfunc{bool}{GetSessionEnding}{\void}
61
62Returns TRUE if the session is ending.
63
64\membersection{wxCloseEvent::GetForce}\label{wxcloseeventgetforce}
65
66\constfunc{bool}{GetForce}{\void}
67
68Returns TRUE if the application wishes to force the window to close.
69This will shortly be obsolete, replaced by CanVeto.
70
71\membersection{wxCloseEvent::SetCanVeto}\label{wxcloseeventsetcanveto}
72
73\func{void}{SetCanVeto}{\param{bool}{ canVeto}}
74
75Sets the 'can veto' flag.
76
77\membersection{wxCloseEvent::SetForce}\label{wxcloseeventsetforce}
78
79\constfunc{void}{SetForce}{\param{bool}{ force}}
80
81Sets the 'force' flag.
82
83\membersection{wxCloseEvent::SetLoggingOff}\label{wxcloseeventsetloggingoff}
84
85\constfunc{void}{SetLoggingOff}{\param{bool}{ loggingOff}}
86
87Sets the 'logging off' flag.
88
89\membersection{wxCloseEvent::Veto}\label{wxcloseeventveto}
90
91\func{void}{Veto}{\param{bool}{ veto = TRUE}}
92
93Call this from your event handler to veto a system shutdown or to signal
94to the calling application that a window close did not happen.
95
96You can only veto a shutdown if \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto} returns
97TRUE.
