  11
  12     This class represents a dialog that shows a short message and a
  13     progress bar. Optionally, it can display ABORT and SKIP buttons,
  14     the elapsed, remaining and estimated time for the end of the progress.
  15
  16     @beginStyleTable
  17     @style{wxPD_APP_MODAL}
  18            Make the progress dialog modal. If this flag is not given, it is
  19            only "locally" modal - that is the input to the parent window is
  20            disabled, but not to the other ones.
  21     @style{wxPD_AUTO_HIDE}
  22            Causes the progress dialog to disappear from screen as soon as the
  23            maximum value of the progress meter has been reached.
  24     @style{wxPD_SMOOTH}
  25            Causes smooth progress of the gauge control.
  26     @style{wxPD_CAN_ABORT}
  27            This flag tells the dialog that it should have a "Cancel" button
  28            which the user may press. If this happens, the next call to
  29            Update() will return @false.
  30     @style{wxPD_CAN_SKIP}
  31            This flag tells the dialog that it should have a "Skip" button
  32            which the user may press. If this happens, the next call to
  33            Update() will return @true in its skip parameter.
  34     @style{wxPD_ELAPSED_TIME}
  35            This flag tells the dialog that it should show elapsed time (since
  36            creating the dialog).
  37     @style{wxPD_ESTIMATED_TIME}
  38            This flag tells the dialog that it should show estimated time.
  39     @style{wxPD_REMAINING_TIME}
  40            This flag tells the dialog that it should show remaining time.
