<para>
#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.

<para>
Note that #GtkFileChooserDialog does not have any methods of its
own. Instead, you should use the functions that work on a
#GtkFileChooser.

<para>
In the simplest of cases, you can the following code to use
#GtkFileChooserDialog to select a file for opening:
</para>
<programlisting>
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,

To use a dialog for saving, you can use this:

GTK_FILE_CHOOSER_ACTION_SAVE,
GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,

<title>Response Codes</title>
<para>
#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 gtk_file_chooser_dialog_new() as follows:
</para>
<programlisting>
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);
</programlisting>
<para>
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,
<emphasis>will</emphasis> have one of the following response
codes:
<simplelist id="gtkfilechooserdialog-responses">
<member>#GTK_RESPONSE_ACCEPT</member>
<member>#GTK_RESPONSE_OK</member>
<member>#GTK_RESPONSE_YES</member>
<member>#GTK_RESPONSE_APPLY</member>
</simplelist>
</para>
<para>
This is because #GtkFileChooserDialog must intercept responses
and switch to folders if appropriate, rather than letting the
dialog terminate &mdash; the implementation uses these known
response codes to know which responses can be blocked if
appropriate.
</para>

<para>
To summarize, make sure you use a <link
linkend="gtkfilechooserdialog-responses">stock response
code</link> when you use #GtkFileChooserDialog to ensure
proper operation.
