Description

GtkFileSelection has been superseded by the newer GtkFileChooser family of widgets.

GtkFileSelection should be used to retrieve file or directory names from the user. It will create a new dialog window containing a directory list, and a file list corresponding to the current working directory. The filesystem can be navigated using the directory list or the drop-down history menu. Alternatively, the TAB key can be used to navigate using filename completion - common in text based editors such as emacs and jed.

File selection dialogs are created with a call to gtk_file_selection_new().

The default filename can be set using gtk_file_selection_set_filename() and the selected filename retrieved using gtk_file_selection_get_filename().

Use gtk_file_selection_complete() to display files and directories that match a given pattern. This can be used for example, to show only *.txt files, or only files beginning with gtk*.

Simple file operations; create directory, delete file, and rename file, are available from buttons at the top of the dialog. These can be hidden using gtk_file_selection_hide_fileop_buttons() and shown again using gtk_file_selection_show_fileop_buttons().

Example 29. Getting a filename from the user.


/* The file selection widget and the string to store the chosen filename */

void store_filename (GtkWidget *widget, gpointer user_data) {
   GtkWidget *file_selector = GTK_WIDGET (user_data);
   const gchar *selected_filename;

   selected_filename = gtk_file_selection_get_filename (GTK_FILE_SELECTION (file_selector));
   g_print ("Selected filename: %s\n", selected_filename);
}

void create_file_selection (void) {

   GtkWidget *file_selector;

   /* Create the selector */
   
   file_selector = gtk_file_selection_new ("Please select a file for editing.");
   
   g_signal_connect (GTK_FILE_SELECTION (file_selector)->ok_button,
                     "clicked",
                     G_CALLBACK (store_filename),
                     file_selector);
   			   
   /* Ensure that the dialog box is destroyed when the user clicks a button. */
   
   g_signal_connect_swapped (GTK_FILE_SELECTION (file_selector)->ok_button,
                             "clicked",
                             G_CALLBACK (gtk_widget_destroy), 
                             file_selector);

   g_signal_connect_swapped (GTK_FILE_SELECTION (file_selector)->cancel_button,
                             "clicked",
                             G_CALLBACK (gtk_widget_destroy),
                             file_selector); 
   
   /* Display that dialog */
   
   gtk_widget_show (file_selector);
}

Warning

GtkFileSelection is deprecated and should not be used in newly-written code.

The GtkFileSelection struct contains the following GtkWidget fields:

GtkWidget *dir_list;
GtkWidget *file_list;
GtkWidget *selection_entry;
GtkWidget *selection_text;
GtkWidget *main_vbox;
GtkWidget *ok_button;
GtkWidget *cancel_button; the two main buttons that signals should be connected to in order to perform an action when the user hits either OK or Cancel.
GtkWidget *help_button;
GtkWidget *history_pulldown; the GtkOptionMenu used to create the drop-down directory history.
GtkWidget *history_menu;
GList *history_list;
GtkWidget *fileop_dialog; the dialog box used to display the GtkFileSelection. It can be customized by adding/removing widgets from it using the standard GtkDialog functions.
GtkWidget *fileop_entry;
gchar *fileop_file;
gpointer cmpl_state;
GtkWidget *fileop_c_dir;
GtkWidget *fileop_del_file;
GtkWidget *fileop_ren_file; the buttons that appear at the top of the file selection dialog. These "operation buttons" can be hidden and redisplayed with gtk_file_selection_hide_fileop_buttons() and gtk_file_selection_show_fileop_buttons() respectively.
GtkWidget *button_area;
GtkWidget *action_area;

gtk_file_selection_new ()

GtkWidget*          gtk_file_selection_new              (const gchar *title);

Warning

gtk_file_selection_new is deprecated and should not be used in newly-written code. Use gtk_file_chooser_dialog_new() instead

Creates a new file selection dialog box. By default it will contain a GtkTreeView of the application's current working directory, and a file listing. Operation buttons that allow the user to create a directory, delete files and rename files, are also present.

title : a message that will be placed in the file requestor's titlebar.
Returns : the new file selection.

gtk_file_selection_set_filename ()

void                gtk_file_selection_set_filename     (GtkFileSelection *filesel,
                                                         const gchar *filename);

Warning

gtk_file_selection_set_filename is deprecated and should not be used in newly-written code.

Sets a default path for the file requestor. If filename includes a directory path, then the requestor will open with that path as its current working directory.

This has the consequence that in order to open the requestor with a working directory and an empty filename, filename must have a trailing directory separator.

The encoding of filename is preferred GLib file name encoding, which may not be UTF-8. See g_filename_from_utf8().

filesel : a GtkFileSelection.
filename : a string to set as the default file name.

gtk_file_selection_get_filename ()

const gchar*        gtk_file_selection_get_filename     (GtkFileSelection *filesel);

Warning

gtk_file_selection_get_filename is deprecated and should not be used in newly-written code.

This function returns the selected filename in the GLib file name encoding. To convert to UTF-8, call g_filename_to_utf8(). The returned string points to a statically allocated buffer and should be copied if you plan to keep it around.

If no file is selected then the selected directory path is returned.

filesel : a GtkFileSelection
Returns : currently-selected filename in the on-disk encoding.

gtk_file_selection_complete ()

void                gtk_file_selection_complete         (GtkFileSelection *filesel,
                                                         const gchar *pattern);

Warning

gtk_file_selection_complete is deprecated and should not be used in newly-written code.

Will attempt to match pattern to a valid filenames or subdirectories in the current directory. If a match can be made, the matched filename will appear in the text entry field of the file selection dialog. If a partial match can be made, the "Files" list will contain those file names which have been partially matched, and the "Folders" list those directories which have been partially matched.

filesel : a GtkFileSelection.
pattern : a string of characters which may or may not match any filenames in the current directory.

gtk_file_selection_show_fileop_buttons ()

void                gtk_file_selection_show_fileop_buttons
                                                        (GtkFileSelection *filesel);

Warning

gtk_file_selection_show_fileop_buttons is deprecated and should not be used in newly-written code.

Shows the file operation buttons, if they have previously been hidden. The rest of the widgets in the dialog will be resized accordingly.

filesel : a GtkFileSelection.

gtk_file_selection_hide_fileop_buttons ()

void                gtk_file_selection_hide_fileop_buttons
                                                        (GtkFileSelection *filesel);

Warning

gtk_file_selection_hide_fileop_buttons is deprecated and should not be used in newly-written code.

Hides the file operation buttons that normally appear at the top of the dialog. Useful if you wish to create a custom file selector, based on GtkFileSelection.

filesel : a GtkFileSelection.

gtk_file_selection_get_selections ()

gchar**             gtk_file_selection_get_selections   (GtkFileSelection *filesel);

Warning

gtk_file_selection_get_selections is deprecated and should not be used in newly-written code.

Retrieves the list of file selections the user has made in the dialog box. This function is intended for use when the user can select multiple files in the file list.

The filenames are in the GLib file name encoding. To convert to UTF-8, call g_filename_to_utf8() on each string.

filesel : a GtkFileSelection
Returns : a newly-allocated NULL-terminated array of strings. Use g_strfreev() to free it.

gtk_file_selection_set_select_multiple ()

void                gtk_file_selection_set_select_multiple
                                                        (GtkFileSelection *filesel,
                                                         gboolean select_multiple);

Warning

gtk_file_selection_set_select_multiple is deprecated and should not be used in newly-written code.

Sets whether the user is allowed to select multiple files in the file list. Use gtk_file_selection_get_selections() to get the list of selected files.

filesel : a GtkFileSelection
select_multiple : whether or not the user is allowed to select multiple files in the file list.

gtk_file_selection_get_select_multiple ()

gboolean            gtk_file_selection_get_select_multiple
                                                        (GtkFileSelection *filesel);

Warning

gtk_file_selection_get_select_multiple is deprecated and should not be used in newly-written code.

Determines whether or not the user is allowed to select multiple files in the file list. See gtk_file_selection_set_select_multiple().

filesel : a GtkFileSelection
Returns : TRUE if the user is allowed to select multiple files in the file list
