* SECTION:gtkfilechooserdialog
* @Short_description: A file chooser dialog, suitable for "File/Open" or "File/Save" commands
* @Title: GtkFileChooserDialog
* @See_also: #GtkFileChooser, #GtkDialog
*
* #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 #GtkFileChooser 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.
*
* <example id="gtkfilechooser-typical-usage">
* <title>Typical usage</title>
* In the simplest of cases, you can the following code to use
* #GtkFileChooserDialog to select a file for opening:
* <para>
* <informalexample><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);
*
* if (gtk_dialog_run (GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT)
* {
* char *filename;
*
* filename = gtk_file_chooser_get_filename (GTK_FILE_CHOOSER (dialog));
* open_file (filename);
* g_free (filename);
* }
*
* gtk_widget_destroy (dialog);
* </programlisting></informalexample>
* </para>
* To use a dialog for saving, you can use this:
* <para>
* <informalexample><programlisting>
* GtkWidget *dialog;
*
* dialog = gtk_file_chooser_dialog_new ("Save File",
* parent_window,
* GTK_FILE_CHOOSER_ACTION_SAVE,
* GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
* GTK_STOCK_SAVE, GTK_RESPONSE_ACCEPT,
* NULL);
* gtk_file_chooser_set_do_overwrite_confirmation (GTK_FILE_CHOOSER (dialog), TRUE);
*
* if (user_edited_a_new_document)
* gtk_file_chooser_set_current_name (GTK_FILE_CHOOSER (dialog), "Untitled document");
* else
* gtk_file_chooser_set_filename (GTK_FILE_CHOOSER (dialog), filename_for_existing_document);
*
* if (gtk_dialog_run (GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT)
* {
* char *filename;
*
* filename = gtk_file_chooser_get_filename (GTK_FILE_CHOOSER (dialog));
* save_to_file (filename);
* g_free (filename);
* }
*
* gtk_widget_destroy (dialog);
* </programlisting></informalexample>
* </para>
* </example>
* <section id="gtkfilechooserdialog-setting-up">
* <title>Setting up a file chooser dialog</title>
* There are various cases in which you may need to use a #GtkFileChooserDialog:
* <itemizedlist><listitem>To select a file for opening, as for a
* <guimenuitem>File/Open</guimenuitem> command. Use
* #GTK_FILE_CHOOSER_ACTION_OPEN.
* </listitem>
* <listitem>To save a file for the first time, as for a
* <guimenuitem>File/Save</guimenuitem> command. Use
* #GTK_FILE_CHOOSER_ACTION_SAVE, and suggest a name such as
* "Untitled" with gtk_file_chooser_set_current_name().
* </listitem>
* <listitem>To save a file under a different name, as for a
* <guimenuitem>File/Save As</guimenuitem> command. Use
* #GTK_FILE_CHOOSER_ACTION_SAVE, and set the existing filename
* with gtk_file_chooser_set_filename().
* </listitem>
* <listitem>To choose a folder instead of a file. Use
* #GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
* </listitem></itemizedlist>
* <note>
* <para>
* Old versions of the file chooser's documentation suggested
* using gtk_file_chooser_set_current_folder() in various
* situations, with the intention of letting the application
* suggest a reasonable default folder. This is no longer
* considered to be a good policy, as now the file chooser is
* able to make good suggestions on its own. In general, you
* should only cause the file chooser to show a specific folder
* when it is appropriate to use gtk_file_chooser_set_filename(),
* i.e. when you are doing a <guimenuitem>File/Save
* As</guimenuitem> command <emphasis>and</emphasis> you already
* have a file saved somewhere.
* </para>
* </note>
* </section>
* <section id="gtkfilechooserdialog-response-codes">
* <title>Response Codes</title>
* #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>
* <informalexample><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></informalexample>
* </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:
* <para>
* <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>
* 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>
* <note>
* To summarize, make sure you use a
* <link linkend="gtkfilechooserdialog-responses">stock response code</link>
* when you use #GtkFileChooserDialog to ensure proper operation.
* </note>
* </para>
* </section>

New handler. Ask the GtkFileChooser widget if it wants to do something 2004-03-04 Federico Mena Quintero <federico@ximian.com> * gtk/gtkfilechooserdialog.c (response_cb): New handler. Ask the GtkFileChooser widget if it wants to do something special rather than letting us terminate the dialog. (gtk_file_chooser_dialog_init): Connect to "response"; see the comment in the sources to see why we don't override the method in class_init. * gtk/gtkfilechooserembed.h (struct _GtkFileChooserEmbedIface): Added a ::should_respond() method. * gtk/gtkfilechooserembed.c (_gtk_file_chooser_embed_delegate_iface_init): Add a delegate for ::should_respond(). (delegate_should_respond): New delegate. (_gtk_file_chooser_embed_should_respond): New function. * gtk/gtkfilechooserdefault.c (set_list_model, create_file_list): Use dashes in signal names rather than underscores. (gtk_file_chooser_default_init): Hook up our ::should_respond() implementation. (gtk_file_chooser_default_should_respond): Implement. go into a folder rather than responding if we are in File mode and the selected file is a folder. (get_selection): New helper function. (add_bookmark_button_clicked_cb): Use get_selection(). (bookmarks_check_add_sensitivity): Likewise. (gtk_file_chooser_default_get_paths): Likewise. (check_save_entry): New helper function. (gtk_file_chooser_default_get_paths): Use check_save_entry(). (selection_check): Renamed from selection_is_folders(). Now checks whether the selection is empty, all files, all folders. (bookmarks_check_add_sensitivity): Use selection_check().

New handler. Ask the GtkFileChooser widget if it wants to do something 2004-03-04 Federico Mena Quintero <federico@ximian.com> * gtk/gtkfilechooserdialog.c (response_cb): New handler. Ask the GtkFileChooser widget if it wants to do something special rather than letting us terminate the dialog. (gtk_file_chooser_dialog_init): Connect to "response"; see the comment in the sources to see why we don't override the method in class_init. * gtk/gtkfilechooserembed.h (struct _GtkFileChooserEmbedIface): Added a ::should_respond() method. * gtk/gtkfilechooserembed.c (_gtk_file_chooser_embed_delegate_iface_init): Add a delegate for ::should_respond(). (delegate_should_respond): New delegate. (_gtk_file_chooser_embed_should_respond): New function. * gtk/gtkfilechooserdefault.c (set_list_model, create_file_list): Use dashes in signal names rather than underscores. (gtk_file_chooser_default_init): Hook up our ::should_respond() implementation. (gtk_file_chooser_default_should_respond): Implement. go into a folder rather than responding if we are in File mode and the selected file is a folder. (get_selection): New helper function. (add_bookmark_button_clicked_cb): Use get_selection(). (bookmarks_check_add_sensitivity): Likewise. (gtk_file_chooser_default_get_paths): Likewise. (check_save_entry): New helper function. (gtk_file_chooser_default_get_paths): Use check_save_entry(). (selection_check): Renamed from selection_is_folders(). Now checks whether the selection is empty, all files, all folders. (bookmarks_check_add_sensitivity): Use selection_check().
