If an outline of your code just consists of:
void check_stuff() {
if (vpn_connections_changed()) std::cout << "XXX changed\n";
}
int main(int argc, char* argv[]) {
for (;;) {
sleep(10);
check_stuff();
}
return 0;
}
Then in gtkmm this just becomes:
bool check_stuff() {
if (vpn_connections_changed()) std::cout << "XXX changed\n";
return true;
}
int main(int argc, char* argv[]) {
Gtk::Main app(argc, argv);
Glib::signal_timeout().connect_seconds(sigc::ptr_fun(&check_stuff), 10);
app.run();
return 0;
}
You can go from there and add your graphical interface to check_stuff()
in place of the call to std::cout. You might, for example, want to
display a Gtk::MessageDialog object. With gtkmm-3.0, you might want
to use Gtk::Application instead of Gtk::Main. But first things first.
