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

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