NAME

       wxProgressDialog - Functions for wxProgressDialog class

DESCRIPTION

       If  supported by the platform this class will provide the platform's native progress dialog, else it will
       simply be the wxGenericProgressDialog (not implemented in wx).

       This class is derived (and can use functions) from: wxDialog wxTopLevelWindow wxWindow wxEvtHandler

       wxWidgets docs: wxProgressDialog

DATA TYPES

       wxProgressDialog() = wx:wx_object()

EXPORTS

       new(Title, Message) -> wxProgressDialog()

              Types:

                 Title = Message = unicode:chardata()

       new(Title, Message, Options :: [Option]) -> wxProgressDialog()

              Types:

                 Title = Message = unicode:chardata()
                 Option =
                     {maximum, integer()} |
                     {parent, wxWindow:wxWindow()} |
                     {style, integer()}

       resume(This) -> ok

              Types:

                 This = wxProgressDialog()

              Can be used to continue with the dialog, after the user had clicked the "Abort" button.

       update(This, Value) -> boolean()

              Types:

                 This = wxProgressDialog()
                 Value = integer()

       update(This, Value, Options :: [Option]) -> boolean()

              Types:

                 This = wxProgressDialog()
                 Value = integer()
                 Option = {newmsg, unicode:chardata()}

              Updates the dialog, setting the progress bar to the new value and updating the message if new  one
              is specified.

              Returns true unless the "Cancel" button has been pressed.

              If  false  is  returned, the application can either immediately destroy the dialog or ask the user
              for the confirmation and if the abort is not confirmed the dialog may  be  resumed  with  resume/1
              function.

              If  value  is  the  maximum value for the dialog, the behaviour of the function depends on whether
              wxPD_AUTO_HIDE was used when the dialog was created. If it was,  the  dialog  is  hidden  and  the
              function  returns  immediately. If it was not, the dialog becomes a modal dialog and waits for the
              user to dismiss it, meaning that this function does not return until this happens.

              Notice that if newmsg is longer than the currently shown message, the dialog will be automatically
              made  wider  to  account  for it. However if the new message is shorter than the previous one, the
              dialog doesn't shrink back to avoid constant resizes if the message is changed often. To  do  this
              and  fit  the  dialog  to its current contents you may call wxWindow:fit/1 explicitly. However the
              native MSW implementation of this class does make the dialog shorter if the  new  text  has  fewer
              lines  of text than the old one, so it is recommended to keep the number of lines of text constant
              in order to avoid jarring dialog size changes. You may also want  to  make  the  initial  message,
              specified  when  creating the dialog, wide enough to avoid having to resize the dialog later, e.g.
              by appending a long string of unbreakable spaces  (wxString  (not  implemented  in  wx)(L'\u00a0',
              100)) to it.

       destroy(This :: wxProgressDialog()) -> ok

              Destroys the object.
