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.

Methods

FileDialog.new

FileDialog.new(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

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

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(String directory)

Sets the default directory.

FileDialog#set_filename

set_filename(String setfilename)

Sets the default filename.

FileDialog#set_filter_index

set_filter_index(Integer filterIndex)

Sets the default filter index, starting from zero.

FileDialog#set_message

set_message(String message)

Sets the message that will be displayed on the dialog.

FileDialog#set_path

set_path(String path)

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

FileDialog#set_wildcard

set_wildcard(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.
