Is it possible to be notified about plugins readonly parameter changes?

[wellington wallace]

Hi!

I would like to be notified when an readonly parameter changes. Consider
for example the current delay or latency of ladspa or lv2 delay plugin. I
tried the following with no success:

self.delay.bind_property('left-delay', self.ui_value, 'value',
GObject.BindingFlags.DEFAULT)

When the property is writable I am notified about its changes but not when
it is readonly. I know that the plugin code made changes to the parameter
because I can see them doing print(self.delay.get_property('left-delay)).

Is there a way to be notified about these changes without having to
periodically calling get_property?

Best regards,

                 Wellington
