* SECTION:gtkmessagedialog
* @Short_description: A convenient message window
* @Title: GtkMessageDialog
* @See_also:#GtkDialog
*
* #GtkMessageDialog presents a dialog with an image representing the type of
* message (Error, Question, etc.) alongside some message text. It's simply a
* convenience widget; you could construct the equivalent of #GtkMessageDialog
* from #GtkDialog without too much effort, but #GtkMessageDialog saves typing.
*
* The easiest way to do a modal message dialog is to use gtk_dialog_run(), though
* you can also pass in the %GTK_DIALOG_MODAL flag, gtk_dialog_run() automatically
* makes the dialog modal and waits for the user to respond to it. gtk_dialog_run()
* returns when any dialog button is clicked.
* <example>
* <title>A modal dialog.</title>
* <programlisting>
* dialog = gtk_message_dialog_new (main_application_window,
* GTK_DIALOG_DESTROY_WITH_PARENT,
* GTK_MESSAGE_ERROR,
* GTK_BUTTONS_CLOSE,
* "Error loading file '%s': %s",
* filename, g_strerror (errno));
* gtk_dialog_run (GTK_DIALOG (dialog));
* gtk_widget_destroy (dialog);
* </programlisting>
* </example>
* You might do a non-modal #GtkMessageDialog as follows:
* <example>
* <title>A non-modal dialog.</title>
* <programlisting>
* dialog = gtk_message_dialog_new (main_application_window,
* GTK_DIALOG_DESTROY_WITH_PARENT,
* GTK_MESSAGE_ERROR,
* GTK_BUTTONS_CLOSE,
* "Error loading file '%s': %s",
* filename, g_strerror (errno));
*
* /* Destroy the dialog when the user responds to it (e.g. clicks a button) */
* g_signal_connect_swapped (dialog, "response",
* G_CALLBACK (gtk_widget_destroy),
* dialog);
* </programlisting>
* </example>
*
* <refsect2 id="GtkMessageDialog-BUILDER-UI">
* <title>GtkMessageDialog as GtkBuildable</title>
* <para>
* The GtkMessageDialog implementation of the GtkBuildable interface exposes
* the message area as an internal child with the name "message_area".
* </para>
* </refsect2>
