14 | ||
15 | To process a close event, use these event handler macros to direct input to member | |
16 | functions that take a wxCloseEvent argument. | |

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