GtkBuildable
and GtkFileChooser
.GtkFileChooserDialog
is a dialog box suitable for use with
"File/Open" or "File/Save as" commands. This widget works by
putting a GtkFileChooserWidget
inside a GtkDialog
. It exposes
the GtkFileChooserIface
interface, so you can use all of the
GtkFileChooser
functions on the file chooser dialog as well as
those for GtkDialog
. Note that GtkFileChooserDialog
does not have any methods of its
own. Instead, you should use the functions that work on a
GtkFileChooser
. Typical usage
###### # Request a file from the user and open it ###### # This is how one creates a dialog with buttons and associated response codes. # (Please ignore the C "Response Code" example in the next section) dialog <- gtkFileChooserDialog("Open File", parent_window, "open", "gtk-cancel", GtkResponseType["cancel"], "gtk-open", GtkResponseType["accept"]) if (dialog$run() == GtkResponseType["accept"]) { filename <- dialog$getFilename() f <- file(filename) } dialog$destroy()
GtkFileChooserDialog
inherits from GtkDialog
, so buttons that
go in its action area have response codes such as
GTK_RESPONSE_ACCEPT
and GTK_RESPONSE_CANCEL
. For example, you
could call gtkFileChooserDialogNew
as follows:
GtkWidget *dialog; dialog = gtk_file_chooser_dialog_new ("Open File", parent_window, GTK_FILE_CHOOSER_ACTION_OPEN, GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL, GTK_STOCK_OPEN, GTK_RESPONSE_ACCEPT, NULL);This will create buttons for "Cancel" and "Open" that use stock response identifiers from
GtkResponseType
. For most dialog
boxes you can use your own custom response codes rather than the
ones in GtkResponseType
, but GtkFileChooserDialog
assumes that
its "accept"-type action, e.g. an "Open" or "Save" button,
will have one of the following response
codes:
GTK_RESPONSE_ACCEPT
GTK_RESPONSE_OK
GTK_RESPONSE_YES
GTK_RESPONSE_APPLY
GtkFileChooserDialog
must intercept responses
and switch to folders if appropriate, rather than letting the
dialog terminate -- the implementation uses these known
response codes to know which responses can be blocked if
appropriate.
PLEASE NOTE: To summarize, make sure you use a stock response
code when you use GtkFileChooserDialog
to ensure
proper operation.gtkFileChooserDialog
is the result of collapsing the constructors of GtkFileChooserDialog
(gtkFileChooserDialogNew
, gtkFileChooserDialogNewWithBackend
) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.GtkFileChooser
