Re: [Flightgear-devel] Listener not firing, 10Hz nasal loop harmful?

[Benedikt H. <be...@ha...>]

Hi,
i stripped down the code to a basic example. and that seems to work.

When i have a Prop node A, and it changes its value, do the aliased 
props also fire a listener?

A<-alias B     setlistener(B)
When A changes, the new value can be read from B; but does an 
setlistener to B also fire when the underlaying prop A changes?
