  12 \section{\class{wxProgressDialog}}\label{wxprogressdialog}
  13
  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
  36 not given, it is only "locally" modal - that is the input to the parent
  37 window is disabled, but not to the other ones.}
  38 \twocolitem{\windowstyle{wxPD\_AUTO\_HIDE}}{Causes the progress dialog to disappear
  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
  47 \helpref{Update()}{wxprogressdialogupdate} will return true in its skip parameter.}
  48 \twocolitem{\windowstyle{wxPD\_ELAPSED\_TIME}}{This flag tells the dialog that it should show elapsed time (since creating the dialog).}
  49 \twocolitem{\windowstyle{wxPD\_ESTIMATED\_TIME}}{This flag tells the dialog that it should show estimated time.}
  50 \twocolitem{\windowstyle{wxPD\_REMAINING\_TIME}}{This flag tells the dialog that it should show remaining time.}

  61  \param{wxWindow * }{parent = NULL},\rtfsp
  62  \param{int }{style = wxPD\_AUTO\_HIDE | wxPD\_APP\_MODAL}}
  63
  64 Constructor. Creates the dialog, displays it and disables user input
  65 for other windows, or, if wxPD\_APP\_MODAL flag is not given, for its parent
  66 window only.
  67
  68 \wxheading{Parameters}
  69
  70 \docparam{title}{Dialog title to show in titlebar.}
  71
  72 \docparam{message}{Message displayed above the progress bar.}
  73
  74 \docparam{maximum}{Maximum value for the progress bar.}
  75
  76 \docparam{parent}{Parent window.}
  77
  78 \docparam{style}{The dialog style. See \helpref{wxProgressDialog}{wxprogressdialog}.}
  79
  80 \membersection{wxProgressDialog::\destruct{wxProgressDialog}}\label{wxprogressdialogdtor}
  81
  82 \func{}{\destruct{wxProgressDialog}}{\void}
  83
  84 Destructor. Deletes the dialog and enables all top level windows.
  85
  86 \membersection{wxProgressDialog::Resume}\label{wxprogressdialogresume}
  87
  88 \func{void}{Resume}{\void}
  89
  90 Can be used to continue with the dialog, after the user had chosen
  91 ABORT.
  92
  93 \membersection{wxProgressDialog::Update}\label{wxprogressdialogupdate}
  94
  95 \func{virtual bool}{Update}{
  96   \param{int }{value},\rtfsp
  97   \param{const wxString\& }{newmsg = ""},\rtfsp
  98   \param{bool *}{skip = NULL}}
  99
 100 Updates the dialog, setting the progress bar to the new value and, if
 101 given changes the message above it. Returns \true unless the Cancel button
 102 has been pressed.
 103
 104 If \false is returned, the application can either immediately destroy the dialog
 105 or ask the user for the confirmation and if the abort is not confirmed the
 106 dialog may be resumed with \helpref{Resume}{wxprogressdialogresume} function.
 107
 108 \wxheading{Parameters}
 109
 110 \docparam{value}{The new value of the progress meter. It should be less than or
 111 equal to the maximum value given to the constructor and the dialog is closed if
 112 it is equal to the maximum.}
 113 \docparam{newmsg}{The new messages for the progress dialog text, if it is
 114 empty (which is the default) the message is not changed.}
 115 \docparam{skip}{If "Skip" button was pressed since last
 116 \helpref{Update}{wxprogressdialogupdate} call, this is set to true.}
 117
 118
 119 \membersection{wxProgressDialog::UpdatePulse}\label{wxprogressdialogupdatepulse}
 120
 121 \func{virtual bool}{UpdatePulse}{
 122   \param{const wxString\& }{newmsg = ""},\rtfsp
 123   \param{bool *}{skip = NULL}}
 124
 125 Just like \helpref{Update}{wxprogressdialogupdate} but makes
 126 the gauge control run in indeterminate mode (see \helpref{wxGauge}{wxgauge} documentation),
 127 sets the remaining and the estimated time labels (if present) to {\tt Unknown} and moves
 128 the progress bar a bit to indicate that some progress was done.
