Add a call to the callback for the meter to set the meter value from the

subroutine?

Sounds like you just need to connect the meter to the subroutine but it's

a bit had to say without a bit more code to demonstrate how you are

setting up the meter.
A few questions...
Is the meter a class of it's own or just a widget in a draw routine?
Do you have a "set_meter_value" type of function or are you just calling

directly to the meter widget's value?
What UI toolkit is the meter using?
