NAME

       wxFileDialog - Functions for wxFileDialog class

DESCRIPTION

       This class represents the file chooser dialog.

       The  path  and  filename  are  distinct  elements  of  a  full  file  pathname. If path is
       ?wxEmptyString, the current directory will be used.  If  filename  is  ?wxEmptyString,  no
       default filename will be supplied. The wildcard determines what files are displayed in the
       file selector, and file extension supplies a type extension for the required filename.

       The typical usage for the open file dialog is:

       The typical usage for the save file dialog is instead somewhat simpler:

       Remark: All implementations of the  wxFileDialog  provide  a  wildcard  filter.  Typing  a
       filename  containing  wildcards (*, ?) in the filename text item, and clicking on Ok, will
       result in only those files matching the pattern being displayed. The  wildcard  may  be  a
       specification  for multiple types of file with a description for each, such as: It must be
       noted that wildcard support in the native Motif file dialog is  quite  limited:  only  one
       file  type  is  supported,  and  it  is displayed without the descriptive test; "BMP files
       (*.bmp)|*.bmp" is displayed as  "*.bmp",  and  both  "BMP  files  (*.bmp)|*.bmp|GIF  files
       (*.gif)|*.gif"  and  "Image  files|*.bmp;*.gif"  are errors. On Mac macOS in the open file
       dialog the filter choice box is not shown by default.  Instead  all  given  wildcards  are
       appplied  at  the  same  time:  So  in  the  above  example all bmp, gif and png files are
       displayed.  To  enforce  the  display  of  the  filter  choice   set   the   corresponding
       wxSystemOptions  before calling the file open dialog: But in contrast to Windows and Unix,
       where the file type choice filters only the selected files, on Mac macOS even in this case
       the  dialog  shows  all  files matching all file types. The files which does not match the
       currently selected file type are greyed out and are not selectable.

DATA TYPES

       wxFileDialog() = wx:wx_object()

EXPORTS

       new(Parent) -> wxFileDialog()

              Types:

                 Parent = wxWindow:wxWindow()

       new(Parent, Options :: [Option]) -> wxFileDialog()

              Types:

                 Parent = wxWindow:wxWindow()
                 Option =
                     {message, unicode:chardata()} |
                     {defaultDir, unicode:chardata()} |
                     {defaultFile, unicode:chardata()} |
                     {wildCard, unicode:chardata()} |
                     {style, integer()} |
                     {pos, {X :: integer(), Y :: integer()}} |
                     {sz, {W :: integer(), H :: integer()}}

              Constructor.

              Use wxDialog:showModal/1 to show the dialog.

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

              Destructor.

       getDirectory(This) -> unicode:charlist()

              Types:

                 This = wxFileDialog()

              Returns the default directory.

       getFilename(This) -> unicode:charlist()

              Types:

                 This = wxFileDialog()

              Returns the default filename.

              Note:  This function can't be used with dialogs which have the wxFD_MULTIPLE style,
              use getFilenames/1 instead.

       getFilenames(This) -> [unicode:charlist()]

              Types:

                 This = wxFileDialog()

              Fills the array filenames with the names of the files chosen.

              This function should only be used with the dialogs which have wxFD_MULTIPLE  style,
              use getFilename/1 for the others.

              Note  that  under  Windows,  if  the  user selects shortcuts, the filenames include
              paths, since the application cannot determine the full path of each referenced file
              by appending the directory containing the shortcuts to the filename.

       getFilterIndex(This) -> integer()

              Types:

                 This = wxFileDialog()

              Returns  the  index  into the list of filters supplied, optionally, in the wildcard
              parameter.

              Before the dialog is shown, this is the index which will be used when the dialog is
              first displayed.

              After the dialog is shown, this is the index selected by the user.

       getMessage(This) -> unicode:charlist()

              Types:

                 This = wxFileDialog()

              Returns the message that will be displayed on the dialog.

       getPath(This) -> unicode:charlist()

              Types:

                 This = wxFileDialog()

              Returns the full path (directory and filename) of the selected file.

              Note:  This function can't be used with dialogs which have the wxFD_MULTIPLE style,
              use getPaths/1 instead.

       getPaths(This) -> [unicode:charlist()]

              Types:

                 This = wxFileDialog()

              Fills the array paths with the full paths of the files chosen.

              This function should only be used with the dialogs which have wxFD_MULTIPLE  style,
              use getPath/1 for the others.

       getWildcard(This) -> unicode:charlist()

              Types:

                 This = wxFileDialog()

              Returns the file dialog wildcard.

       setDirectory(This, Directory) -> ok

              Types:

                 This = wxFileDialog()
                 Directory = unicode:chardata()

              Sets the default directory.

       setFilename(This, Setfilename) -> ok

              Types:

                 This = wxFileDialog()
                 Setfilename = unicode:chardata()

              Sets the default filename.

              In  wxGTK  this  will  have little effect unless a default directory has previously
              been set.

       setFilterIndex(This, FilterIndex) -> ok

              Types:

                 This = wxFileDialog()
                 FilterIndex = integer()

              Sets the default filter index, starting from zero.

       setMessage(This, Message) -> ok

              Types:

                 This = wxFileDialog()
                 Message = unicode:chardata()

              Sets the message that will be displayed on the dialog.

       setPath(This, Path) -> ok

              Types:

                 This = wxFileDialog()
                 Path = unicode:chardata()

              Sets the path (the combined directory and filename that will be returned  when  the
              dialog is dismissed).

       setWildcard(This, WildCard) -> ok

              Types:

                 This = wxFileDialog()
                 WildCard = unicode:chardata()

              Sets  the  wildcard, which can contain multiple file types, for example: "BMP files
              (*.bmp)|*.bmp|GIF files (*.gif)|*.gif".

              Note that the native Motif dialog has some limitations with respect  to  wildcards;
              see the Remarks section above.
