#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>
</para>
<para>
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 (GTK_OBJECT (dialog), "response",
G_CALLBACK (gtk_widget_destroy),
GTK_OBJECT (dialog));
</programlisting>
</example>
