It almost worked with latest gpsim too. There have been a few changes:
- The modules should have a destructor that free ports, breaks and the
interface.
LcdDisplay::~LcdDisplay()
{
gpsim_unregister_interface(interface_id);
delete data_port;
gpsim_clear_break(control_port);
delete control_port;
gtk_widget_destroy(window);
// free other data...
}
- There is a gpsim_register_gui_update, that registers a function to
be called when the gui should update (controlled from the gpsim main
window).
gpsim crashes when you close the window. This is not so nice:
gtk_signal_connect (GTK_OBJECT (window), "destroy",
GTK_SIGNAL_FUNC (gtk_main_quit), NULL);
There should perhaps instead be a handler for the "delete_event" signal,
but I'm not sure what to do with it. Other gui windows have a menu item
to re-open the windows, perhaps we can create a function in gpsim that
modules call to add a menu item to gpsim's windows menu?
, Or perhaps you can simply ignore the delete signal (do nothing and
return TRUE in the handler?).
And I see that a bug followed from gpsim to your module. The module
list must have a ending {NULL,NULL,NULL}.
