Interface
GtkFileChooser
Description [src]
interface Gtk.FileChooser : GObject.Object
GtkFileChooser is an interface that can be implemented by file
selection widgets.
In GTK, the main objects that implement this interface are
GtkFileChooserWidget and GtkFileChooserDialog.
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 filenames as GFiles.
Adding options
You can add extra widgets to a file chooser to provide options
that are not present in the default design, by using
gtk_file_chooser_add_choice(). Each choice has an identifier and
a user visible label; additionally, each choice can have multiple
options. If a choice has no option, it will be rendered as a
check button with the given label; if a choice has options, it will
be rendered as a combo box.
Prerequisite
In order to implement FileChooser, your type must inherit from
GObject.
