/**
* SECTION:gtkfilechooser
* @Short_description: File chooser interface used by GtkFileChooserWidget and GtkFileChooserDialog
* @Title: GtkFileChooser
* @See_also: #GtkFileChooserDialog, #GtkFileChooserWidget, #GtkFileChooserButton
*
* #GtkFileChooser is an interface that can be implemented by file
* selection widgets. In GTK+, the main objects that implement this
* interface are #GtkFileChooserWidget, #GtkFileChooserDialog, and
* #GtkFileChooserButton. You do not need to write an object that
* implements the #GtkFileChooser interface unless you are trying to
* adapt an existing file selector to expose a standard programming
* interface.
*
* #GtkFileChooser allows for shortcuts to various places in the filesystem.
* In the default implementation these are displayed in the left pane. It
* may be a bit confusing at first that these shortcuts come from various
* sources and in various flavours, so lets explain the terminology here:
*
*
* Bookmarks
*
* are created by the user, by dragging folders from the
* right pane to the left pane, or by using the "Add". Bookmarks
* can be renamed and deleted by the user.
*
*
*
* Shortcuts
*
* can be provided by the application. For example, a Paint program may
* want to add a shortcut for a Clipart folder. Shortcuts cannot be modified by the
* user.
*
*
*
* Volumes
*
* are provided by the underlying filesystem abstraction. They are
* the "roots" of the filesystem.
*
*
*
*
*
* File Names and Encodings
* When the user is finished selecting files in a
* #GtkFileChooser, your program can get the selected names
* either as filenames or as URIs. For URIs, the normal escaping
* rules are applied if the URI contains non-ASCII characters.
* However, filenames are always returned in
* the character set specified by the
* G_FILENAME_ENCODING environment variable.
* Please see the GLib documentation for more details about this
* variable.
*
* This means that while you can pass the result of
* gtk_file_chooser_get_filename() to
* open(2) or
* fopen(3), you may not be able to
* directly set it as the text of a #GtkLabel widget unless you
* convert it first to UTF-8, which all GTK+ widgets expect.
* You should use g_filename_to_utf8() to convert filenames
* into strings that can be passed to GTK+ widgets.
*
*
*
* Adding a Preview Widget
*
* You can add a custom preview widget to a file chooser and then
* get notification about when the preview needs to be updated.
* To install a preview widget, use
* gtk_file_chooser_set_preview_widget(). Then, connect to the
* #GtkFileChooser::update-preview signal to get notified when
* you need to update the contents of the preview.
*
*
* Your callback should use
* gtk_file_chooser_get_preview_filename() to see what needs
* previewing. Once you have generated the preview for the
* corresponding file, you must call
* gtk_file_chooser_set_preview_widget_active() with a boolean
* flag that indicates whether your callback could successfully
* generate a preview.
*
*
* Sample Usage
*
* {
* GtkImage *preview;
*
* ...
*
* preview = gtk_image_new ();
*
* gtk_file_chooser_set_preview_widget (my_file_chooser, preview);
* g_signal_connect (my_file_chooser, "update-preview",
* G_CALLBACK (update_preview_cb), preview);
* }
*
* static void
* update_preview_cb (GtkFileChooser *file_chooser, gpointer data)
* {
* GtkWidget *preview;
* char *filename;
* GdkPixbuf *pixbuf;
* gboolean have_preview;
*
* preview = GTK_WIDGET (data);
* filename = gtk_file_chooser_get_preview_filename (file_chooser);
*
* pixbuf = gdk_pixbuf_new_from_file_at_size (filename, 128, 128, NULL);
* have_preview = (pixbuf != NULL);
* g_free (filename);
*
* gtk_image_set_from_pixbuf (GTK_IMAGE (preview), pixbuf);
* if (pixbuf)
* g_object_unref (pixbuf);
*
* gtk_file_chooser_set_preview_widget_active (file_chooser, have_preview);
* }
*
*
*
*
* Adding Extra Widgets
*
* You can add extra widgets to a file chooser to provide options
* that are not present in the default design. For example, you
* can add a toggle button to give the user the option to open a
* file in read-only mode. You can use
* gtk_file_chooser_set_extra_widget() to insert additional
* widgets in a file chooser.
*
*
* Sample Usage
*
*
* GtkWidget *toggle;
*
* ...
*
* toggle = gtk_check_button_new_with_label ("Open file read-only");
* gtk_widget_show (toggle);
* gtk_file_chooser_set_extra_widget (my_file_chooser, toggle);
* }
*
*
*
* If you want to set more than one extra widget in the file
* chooser, you can a container such as a #GtkBox or a #GtkGrid
* and include your widgets in it. Then, set the container as
* the whole extra widget.
*
*
*
* Key Bindings
*
* Internally, GTK+ implements a file chooser's graphical user
* interface with the private
* GtkFileChooserDefaultClass. This
* widget has several key
* bindings and their associated signals. This section
* describes the available key binding signals.
*
*
* GtkFileChooser key binding example
*
* The default keys that activate the key-binding signals in
* GtkFileChooserDefaultClass are as
* follows:
*
*
*
*
*
* Signal name
* Default key combinations
*
*
* location-popup
*
* ControlL (empty path);
* / (path of "/")
*
* Both the individual / key and the
* numeric keypad's "divide" key are supported.
* ;
* ~ (path of "~")
*
*
*
* up-folder
*
* AltUp;
* AltShiftUp
*
* Both the individual Up key and the numeric
* keypad's Up key are supported.
* ;
* Backspace
*
*
*
* down-folder
*
* AltDown;
* AltShiftDown
*
* Both the individual Down key and the numeric
* keypad's Down key are supported.
*
*
*
*
* home-folder
* AltHome
*
*
* desktop-folder
* AltD
*
*
* quick-bookmark
* Alt1 through Alt0
*
*
*
*
*
* You can change these defaults to something else. For
* example, to add a Shift modifier to a few
* of the default bindings, you can include the following
* fragment in your .config/gtk-3.0/gtk.css file:
*
*
* @binding-set MyOwnFilechooserBindings
* {
* bind "<Alt><Shift>Up" { "up-folder" () }
* bind "<Alt><Shift>Down" { "down-folder" () }
* bind "<Alt><Shift>Home" { "home-folder" () }
* }
*
* GtkFileChooserDefault
* {
* gtk-key-bindings: MyOwnFilechooserBindings
* }
*
*
*
* The "GtkFileChooserDefault::location-popup" signal
*
* void user_function (GtkFileChooserDefault *chooser,
* const char *path,
* gpointer user_data);
*
*
* This is used to make the file chooser show a "Location"
* dialog which the user can use to manually type the name of
* the file he wishes to select. The
* path argument is a string that gets
* put in the text entry for the file name. By default this is bound to
* ControlL
* with a path string of "" (the empty
* string). It is also bound to / with a
* path string of "/"
* (a slash): this lets you type / and
* immediately type a path name. On Unix systems, this is bound to
* ~ (tilde) with a path string
* of "~" itself for access to home directories.
*
*
*
* chooser :
*
*
* the object which received the signal.
*
*
*
*
* path :
*
*
* default contents for the text entry for the file name
*
*
*
*
* user_data :
*
*
* user data set when the signal handler was connected.
*
*
*
*
*
* You can create your own bindings for the
* #GtkFileChooserDefault::location-popup signal with custom
* path strings, and have a crude form
* of easily-to-type bookmarks. For example, say you access
* the path /home/username/misc very
* frequently. You could then create an
* AltM
* shortcut by including the following in your
* .config/gtk-3.0/gtk.css:
*
* @binding-set MiscShortcut
* {
* bind "<Alt>M" { "location-popup" ("/home/username/misc") }
* }
*
* GtkFileChooserDefault
* {
* gtk-key-bindings: MiscShortcut
* }
*
*
*
*
* The "GtkFileChooserDefault::up-folder" signal
*
* void user_function (GtkFileChooserDefault *chooser,
* gpointer user_data);
*
*
* This is used to make the file chooser go to the parent of
* the current folder in the file hierarchy. By default this
* is bound to Backspace and
* AltUp
* (the Up key in the numeric keypad also works).
*
*
*
* chooser :
*
*
* the object which received the signal.
*
*
*
*
* user_data :
*
*
* user data set when the signal handler was connected.
*
*
*
*
*
*
* The "GtkFileChooserDefault::down-folder" signal
*
* void user_function (GtkFileChooserDefault *chooser,
* gpointer user_data);
*
*
* This is used to make the file chooser go to a child of the
* current folder in the file hierarchy. The subfolder that
* will be used is displayed in the path bar widget of the file
* chooser. For example, if the path bar is showing
* "/foo/bar/baz", then this will cause
* the file chooser to switch to the "baz" subfolder. By
* default this is bound to
* AltDown
* (the Down key in the numeric keypad also works).
*
*
*
* chooser :
*
*
* the object which received the signal.
*
*
*
*
* user_data :
*
*
* user data set when the signal handler was connected.
*
*
*
*
*
*
* The "GtkFileChooserDefault::home-folder" signal
*
* void user_function (GtkFileChooserDefault *chooser,
* gpointer user_data);
*
*
* This is used to make the file chooser show the user's home
* folder in the file list. By default this is bound to
* AltHome
* (the Home key in the numeric keypad also works).
*
*
*
* chooser :
*
*
* the object which received the signal.
*
*
*
*
* user_data :
*
*
* user data set when the signal handler was connected.
*
*
*
*
*
*
* The "GtkFileChooserDefault::desktop-folder" signal
*
* void user_function (GtkFileChooserDefault *chooser,
* gpointer user_data);
*
*
* This is used to make the file chooser show the user's Desktop
* folder in the file list. By default this is bound to
* AltD.
*
*
*
* chooser :
*
*
* the object which received the signal.
*
*
*
*
* user_data :
*
*
* user data set when the signal handler was connected.
*
*
*
*
*
*
* The "GtkFileChooserDefault::quick-bookmark" signal
*
* void user_function (GtkFileChooserDefault *chooser,
* gint bookmark_index,
* gpointer user_data);
*
*
* This is used to make the file chooser switch to the bookmark
* specified in the bookmark_index parameter.
* For example, if you have three bookmarks, you can pass 0, 1, 2 to
* this signal to switch to each of them, respectively. By default this is bound to
* Alt1,
* Alt2,
* etc. until
* Alt0. Note
* that in the default binding,
* that Alt1 is
* actually defined to switch to the bookmark at index 0, and so on
* successively;
* Alt0 is
* defined to switch to the bookmark at index 10.
*
*
*
* chooser :
*
*
* the object which received the signal.
*
*
*
*
* bookmark_indes :
*
*
* index of the bookmark to switch to; the indices start at 0.
*
*
*
*
* user_data :
*
*
* user data set when the signal handler was connected.

* This signal gets emitted whenever it is appropriate to present a

*
* Most applications just need to turn on the
