This signal does not work on native file choosers, and it exposes internals of the widget that should not be public. And it is just not very interesting.

|
||
* @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 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.
