You need to call gtk_run_dialog() again. Try something like this:
done = FALSE;
while (!done) {
switch (gtk_dialog_run(dialog)) {
case GTK_RESPONSE_OK:
if (data valid) {
/* do whatever */
done = TRUE;
} else {
/* complain */
}
break;
case GTK_RESPONSE_CANCEL:
case GTK_RESPONSE_DELETE_EVENT:
/* do whatever */
done = TRUE;
break;
}
}
Better yet, dont make the OK button sensitive until the user has entered
something into the filename field.
