  27 Constructor. Creates the dialog, displays it and disables user input
  28 for other windows, or, if wxPD\_APP\_MODAL flag is not given, for its parent
  29 window only.
  30
  31 \wxheading{Parameters}
  32
  33 \docparam{title}{Dialog title to show in titlebar.}
  34
  35 \docparam{message}{Message displayed above the progress bar.}
  36
  37 \docparam{maximum}{Maximum value for the progress bar.}
  38
  39 \docparam{parent}{Parent window.}
  40
  41 \docparam{message}{Message to show on the dialog.}
  42
  43 \docparam{style}{The dialog style. This is the combination of the following
  44 bitmask constants defined in wx/defs.h:
  45
  46 \twocolwidtha{7cm}
  47 \begin{twocollist}\itemsep=0pt
  48 \twocolitem{{\bf wxPD\_APP\_MODAL}}{Make the progress dialog modal. If this flag is
  49 not given, it is only "locally" modal - that is the input to the parent
  50 window is disabled, but not to the other ones.}
  51 \twocolitem{{\bf wxPD\_AUTO\_HIDE}}{By default, the progress dialog will disappear
  52 from screen as soon as the maximum value of the progress meter has been
  53 reached. This flag prevents it from doing it - instead the dialog will wait
  54 until the user closes it.}
  55 \twocolitem{{\bf wxPD\_CAN\_ABORT}}{This flag tells the dialog that it should have a
  56 "Cancel" button which the user may press. If this happens, the next call to
  57  \helpref{Update()}{wxprogressdialogupdate} will return FALSE.}
  58 \twocolitem{{\bf wxPD\_ELAPSED\_TIME}}{This flag tells the dialog that it should show elapsed time (since creating the dialog).}
  59 \twocolitem{{\bf wxPD\_ESTIMATED\_TIME}}{This flag tells the dialog that it should show estimated time.}
  60 \twocolitem{{\bf wxPD\_REMAINING\_TIME}}{This flag tells the dialog that it should show remaining time.}
  61 \twocolitem{{\bf wxPD\_SMOOTH}}{This flag tells the dialog that it should use
  62 smooth gauge (has effect only under 32bit Windows).}
  63 \end{twocollist}%
  64 }
  65
  66 \membersection{wxProgressDialog::\destruct{wxProgressDialog}}
  67
  68 \func{}{\destruct{wxMessageDialog}}{\void}
  69
  70 Destructor. Deletes the dialog and enables all top level windows.
  71
  72 \membersection{wxProgressDialog::Update}\label{wxprogressdialogupdate}
  73
  74 \func{bool}{Update}{
  75   \param{int }{value = -1},\rtfsp
  76   \param{const char * }{newmsg = NULL},  }
  77
  78 Updates the dialog, setting the progress bar to the new value and, if
  79 given changes the message above it. Returns TRUE if the ABORT button
  80 has \emph{not} been pressed.
  81
  82 If FALSE is returned, the application can either immediately destroy the dialog
  83 or ask the user for the confirmation and if the abort is not confirmed the
  84 dialog may be resumed with \helpref{Resume}{wxprogressdialogresume} function.
  85
  86 \docparam{value}{The new value of the progress meter. It must be strictly less
  87 than the maximum value given to the constructor (i.e., as usual in C, the
  88 index runs from $0$ to $maximum-1$).}
  89 \docparam{newmsg}{The new messages for the progress dialog text, if none is
  90 given the message is not changed.}
  91
  92 \membersection{wxProgressDialog::Resume}\label{wxprogressdialogresume}
  93
  94 \func{void}{Resume}{\void}
  95
  96 Can be used to continue with the dialog, after the user had chosen
  97 ABORT.
