<para>
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.
</para>
<para>
GTK+ treats a dialog as a window split vertically. The top section is a
#GtkVBox known as the <structfield>content_area</structfield>, 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.
</para>
<para>
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.
</para>
<para>
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.
</para>
<para>
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.
</para>
<para>
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
"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 "response" signal will be emitted with a response ID of #GTK_RESPONSE_DELETE_EVENT.
</para>
<para>
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.
</para>
<para>
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 <structname>GtkDialog</structname> 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>
</para>
<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 &lt;action-widgets&gt; element, which
can contain multiple &lt;action-widget&gt; 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">
