Hi,
I use a function like this:
void Centro::dialog_error(const char *display_msg)
{
Gtk::MessageDialog dialog(*mp_window, "Errore", false,
Gtk::MESSAGE_ERROR);
dialog.set_secondary_text(display_msg);
dialog.run();
dialog.hide();
}
...even though dialog.hide() is actually not needed since the dialog is
destroyed as soon as the user clicks on ok/close/anything.
Cheers,
Giuseppe.
