/**
|

* 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() or fopen(),
|
||
* 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.
|
||
*
|
||
* ## Example: Using a Preview Widget ## {#gtkfilechooser-preview}
|
||
* |[<!-- language="C" -->
|
||
* {
|
||
* 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.
|
||
*
|
||
* An example for adding extra widgets:
|
||
* |[<!-- language="C" -->
|
||
*
|
||
* 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.
