/**
* SECTION:gtkdialog
* @Short_description: Create popup windows
* @Title: GtkDialog
* @See_also: #GtkVBox, #GtkWindow, #GtkButton
*
* Dialog boxes are a convenient way to prompt the user for a small amount
* of input, e.g. to display a message, ask a question, or anything else
* that does not require extensive effort on the user's part.
*
* GTK+ treats a dialog as a window split vertically. The top section is a
* #GtkVBox, and is where widgets such as a #GtkLabel or a #GtkEntry should
* be packed. The bottom area is known as the
* <structfield>action_area</structfield>. This is generally used for
* packing buttons into the dialog which may perform functions such as
* cancel, ok, or apply.
*
* #GtkDialog boxes are created with a call to gtk_dialog_new() or
* gtk_dialog_new_with_buttons(). gtk_dialog_new_with_buttons() is
* recommended; it allows you to set the dialog title, some convenient flags,
* and add simple buttons.
*
* If 'dialog' is a newly created dialog, the two primary areas of the
* window can be accessed through gtk_dialog_get_content_area() and
* gtk_dialog_get_action_area(), as can be seen from the example below.
*
* A 'modal' dialog (that is, one which freezes the rest of the application
* from user input), can be created by calling gtk_window_set_modal() on the
* dialog. Use the GTK_WINDOW() macro to cast the widget returned from
* gtk_dialog_new() into a #GtkWindow. When using gtk_dialog_new_with_buttons()
* you can also pass the #GTK_DIALOG_MODAL flag to make a dialog modal.
*
* If you add buttons to #GtkDialog using gtk_dialog_new_with_buttons(),
* gtk_dialog_add_button(), gtk_dialog_add_buttons(), or
* gtk_dialog_add_action_widget(), clicking the button will emit a signal
* called #GtkDialog::response with a response ID that you specified. GTK+
* will never assign a meaning to positive response IDs; these are entirely
* user-defined. But for convenience, you can use the response IDs in the
* #GtkResponseType enumeration (these all have values less than zero). If
* a dialog receives a delete event, the #GtkDialog::response signal will
* be emitted with a response ID of #GTK_RESPONSE_DELETE_EVENT.
*
* If you want to block waiting for a dialog to return before returning
* control flow to your code, you can call gtk_dialog_run(). This function
* enters a recursive main loop and waits for the user to respond to the
* dialog, returning the response ID corresponding to the button the user
* clicked.
*
* For the simple dialog in the following example, in reality you'd probably
* use #GtkMessageDialog to save yourself some effort. But you'd need to
* create the dialog contents manually if you had more than a simple message
* in the dialog.
* <example>
* <title>Simple GtkDialog usage</title>
* <programlisting>
* /* Function to open a dialog box displaying the message provided. */
* void
* quick_message (gchar *message)
* {
* GtkWidget *dialog, *label, *content_area;
*
* /* Create the widgets */
* dialog = gtk_dialog_new_with_buttons ("Message",
* main_application_window,
* GTK_DIALOG_DESTROY_WITH_PARENT,
* GTK_STOCK_OK,
* GTK_RESPONSE_NONE,
* NULL);
* content_area = gtk_dialog_get_content_area (GTK_DIALOG (dialog));
* label = gtk_label_new (message);
*
* /* Ensure that the dialog box is destroyed when the user responds */
* g_signal_connect_swapped (dialog,
* "response",
* G_CALLBACK (gtk_widget_destroy),
* dialog);
*
* /* Add the label, and show everything we've added to the dialog */
*
* gtk_container_add (GTK_CONTAINER (content_area), label);
* gtk_widget_show_all (dialog);
* }
* </programlisting>
* </example>
*
* <refsect2 id="GtkDialog-BUILDER-UI"><title>GtkDialog as GtkBuildable</title>
* <para>
* The GtkDialog implementation of the #GtkBuildable interface exposes the
* @vbox and @action_area as internal children with the names "vbox" and
* "action_area".
* </para>
* <para>
* GtkDialog supports a custom <action-widgets> element, which
* can contain multiple <action-widget> elements. The "response"
* attribute specifies a numeric response, and the content of the element
* is the id of widget (which should be a child of the dialogs @action_area).
* </para>
* <example>
* <title>A <structname>GtkDialog</structname> UI definition fragment.</title>
* <programlisting><![CDATA[
* <object class="GtkDialog" id="dialog1">
* <child internal-child="vbox">"
* <object class="GtkVBox" id="vbox">
* <child internal-child="action_area">
* <object class="GtkHButtonBox" id="button_box">
* <child>

* <action-widget response="3">button_ok</action-widget>
* <action-widget response="-5">button_cancel</action-widget>
