954 * signal. Destroying the dialog during gtk_dialog_run() is a very bad
955 * idea, because your post-run code won't know whether the dialog was
958 * After gtk_dialog_run() returns, you are responsible for hiding or
959 * destroying the dialog if you wish to do so.

973 * gtk_widget_destroy (dialog);
974 * </programlisting></informalexample>
976 * Note that even though the recursive main loop gives the effect of a
977 * modal dialog (it prevents the user from interacting with other
978 * windows while the dialog is run), callbacks such as timeouts,
979 * IO channel watches, DND drops, etc, <emphasis>will</emphasis> be
980 * triggered during a gtk_dialog_run() call.
982 * Return value: response ID
