Thanks. It does look useful. Seems to be written for gtk2 though. Have you
compiled it with gtk3?

at the very least, it would need a draw() method rather than an expose() method.

plus, if i read it correctly it also redraws its entire self (subject to cairo clipping) on every expose.

contrast with the the fastmeter in ardour3's libs/gtkmm2ext which draws only the changed pixels per expose.
