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 fil-
ter. 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 multi-
ple 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.
