# Wx::FileDialog

This class represents the file chooser dialog.

## Derived from

Dialog

Window

EvtHandler

Object

## Window styles

`FD_DEFAULT_STYLE` | Equivalent to FD_OPEN.
`FD_OPEN` | This is an open dialog; usually this means that the default button’s label of the dialog is “Open”. Cannot be combined with FD_SAVE.
`FD_SAVE` | This is a save dialog; usually this means that the default button’s label of the dialog is “Save”. Cannot be combined with FD_OPEN.
`FD_OVERWRITE_PROMPT` | For save dialog only: prompt for a confirmation if a file will be overwritten.
`FD_FILE_MUST_EXIST` | For open dialog only: the user may only select files that actually exist.
`FD_MULTIPLE` | For open dialog only: allows selecting multiple files.
`FD_CHANGE_DIR` | Change the current working directory to the directory where the file(s) chosen by the user are.
`FD_PREVIEW` | Show the preview of the selected files (currently only supported by GTK using GTK+ 2.4 or later).

NB: Previous versions of wxRuby used `FD_CHANGE_DIR` by default
under MS Windows which allowed the program to simply remember the last
directory where user selected the files to open/save. This (desired)
functionality must be implemented in the program itself now (manually remember
the last path used and pass it to the dialog the next time it is called) or
by using this flag.

## Remarks

Pops up a file selector box. In Windows and GTK2.4+, this is the common
file selector dialog. In X, this is a file selector box with somewhat
less functionality. The path and filename are distinct elements of a
full file pathname. If path is ``“, the current directory will be
used. If filename is ``”, 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.

Both the X and Windows versions implement 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:

BMP and GIF files (*.bmp;*.gif)|*.bmp;*.gif|PNG files (*.png)|*.png

It must be noted that wildcard support in the native Motif file dialog
is quite limited: only one alternative 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.

- FileDialog#get_filenames
- FileDialog#get_filter_index
- FileDialog#get_message

### FileDialog.new

FileDialog.new(%(arg-type)Window% parent, String message = “Choose a file”, String defaultDir = "", String defaultFile = "", String wildcard = “.*”, Integer style = FD_DEFAULT_STYLE, Point pos = DEFAULT_POSITION, Size sz = DEFAULT_SIZE, String name = “filedlg”)

Constructor. Use FileDialog#show_modal to show the dialog.

#### Parameters

- parent Parent window.
- message Message to show on the dialog.
- defaultDir The default directory, or the empty string.
- defaultFile The default filename, or the empty string.
- wildcard A wildcard, such as *.* or 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.

- style A dialog style. See the `FD_*` styles, above, for more info.
- pos Dialog position. Not implemented.
- size Dialog size. Not implemented.
- name Dialog name. Not implemented.

### FileDialog#get_directory

String get_directory()

Returns the default directory.

### FileDialog#get_filename

String get_filename()

Returns the default filename.

### FileDialog#get_filenames

Array get_filenames()

Returns an array of strings of the names of the files chosen. This
function should only be used with the dialogs which have `MULTIPLE`
style, use get_filename 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.

### FileDialog#get_filter_index

Integer get_filter_index()

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.

### FileDialog#get_message

String get_message()

Returns the message that will be displayed on the dialog.

### FileDialog#get_path

String get_path()

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

### FileDialog#get_paths

Array get_paths()

Returns an array with the full paths of the files chosen. This function
should only be used with the dialogs which have `MULTIPLE` style, use
get_path for the others.

### FileDialog#get_wildcard

String get_wildcard()

Returns the file dialog wildcard.

### FileDialog#set_directory

set_directory(%(arg-type)String% directory)

Sets the default directory.

### FileDialog#set_filename

set_filename(%(arg-type)String% setfilename)

Sets the default filename.

### FileDialog#set_filter_index

set_filter_index(%(arg-type)Integer% filterIndex)

Sets the default filter index, starting from zero.

### FileDialog#set_message

set_message(%(arg-type)String% message)

Sets the message that will be displayed on the dialog.

### FileDialog#set_path

set_path(%(arg-type)String% path)

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

### FileDialog#set_wildcard

set_wildcard(%(arg-type)String% wildCard)

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.

### FileDialog#show_modal

Integer show_modal()

Shows the dialog, returning `Wx::ID_OK` if the user pressed OK, and
`Wx::ID_CANCEL` otherwise.
