14 This class represents a dialog that shows a short message and a
15 progress bar. Optionally, it can display ABORT and SKIP buttons,
16 the elapsed, remaining and estimated time for the end of the progress.

35 \twocolitem{\windowstyle{wxPD\_APP\_MODAL}}{Make the progress dialog modal. If this flag is

37 window is disabled, but not to the other ones.}

39 from screen as soon as the maximum value of the progress meter has been
40 reached.}
41 \twocolitem{\windowstyle{wxPD\_SMOOTH}}{Causes smooth progress of the gauge control.}
42 \twocolitem{\windowstyle{wxPD\_CAN\_ABORT}}{This flag tells the dialog that it should have a
43 "Cancel" button which the user may press. If this happens, the next call to
44 \helpref{Update()}{wxprogressdialogupdate} will return false.}
45 \twocolitem{\windowstyle{wxPD\_CAN\_SKIP}}{This flag tells the dialog that it should have a
46 "Skip" button which the user may press. If this happens, the next call to

48 \twocolitem{\windowstyle{wxPD\_ELAPSED\_TIME}}{This flag tells the dialog that it should show elapsed time (since creating the dialog).}

61
62 Constructor. Creates the dialog, displays it and disables user input
63 for other windows, or, if wxPD\_APP\_MODAL flag is not given, for its parent
64 window only.
65
66 \wxheading{Parameters}
67
68 \docparam{title}{Dialog title to show in titlebar.}
69
70 \docparam{message}{Message displayed above the progress bar.}
71
72 \docparam{maximum}{Maximum value for the progress bar.}
73
74 \docparam{parent}{Parent window.}
75
76 \docparam{style}{The dialog style. See \helpref{wxProgressDialog}{wxprogressdialog}.}
77
78 \membersection{wxProgressDialog::\destruct{wxProgressDialog}}\label{wxprogressdialogdtor}
79
80 \func{}{\destruct{wxProgressDialog}}{\void}
81
82 Destructor. Deletes the dialog and enables all top level windows.
83
84 \membersection{wxProgressDialog::Resume}\label{wxprogressdialogresume}
85
86 \func{void}{Resume}{\void}
87
88 Can be used to continue with the dialog, after the user had chosen
89 ABORT.
90
91 \membersection{wxProgressDialog::Update}\label{wxprogressdialogupdate}
92
93 \func{virtual bool}{Update}{\param{int }{value}, \param{const wxString\& }{newmsg = ""},\rtfsp
94 \param{bool *}{skip = NULL}}
95
96 Updates the dialog, setting the progress bar to the new value and, if
97 given changes the message above it. Returns \true unless the Cancel button
98 has been pressed.
99
100 If \false is returned, the application can either immediately destroy the dialog
101 or ask the user for the confirmation and if the abort is not confirmed the
102 dialog may be resumed with \helpref{Resume}{wxprogressdialogresume} function.
103
104 \wxheading{Parameters}
105
106 \docparam{value}{The new value of the progress meter. It should be less than or
107 equal to the maximum value given to the constructor and the dialog is closed if
108 it is equal to the maximum.}
109 \docparam{newmsg}{The new messages for the progress dialog text, if it is
110 empty (which is the default) the message is not changed.}
111 \docparam{skip}{If "Skip" button was pressed since last
112 \helpref{Update}{wxprogressdialogupdate} call, this is set to true.}
113
114
115 \membersection{wxProgressDialog::Pulse}\label{wxprogressdialogpdatepulse}
116
117 \func{virtual bool}{Pulse}{\param{const wxString\& }{newmsg = ""},\rtfsp
118 \param{bool *}{skip = NULL}}
119
120 Just like \helpref{Update}{wxprogressdialogupdate} but makes
121 the gauge control run in indeterminate mode (see \helpref{wxGauge}{wxgauge} documentation),
122 sets the remaining and the estimated time labels (if present) to {\tt Unknown} and moves
123 the progress bar a bit to indicate that some progress was done.
