Hi Chris,

Such Qt4 widgets plugin (library) would be great!
In clam we already have a Qt4 plugin useful giving the user the ability
to desig the front-end of a clam processing network:
http://iua-share.upf.es/wikis/clam/index.php/Network_Editor_tutorial

The widgets in our plugin are not sliders and knobs, but for data
visualization (a.k.a. "monitors") such as oscilloscope, spectrogram,
sinusoidal peaks, chord-space (tonal), etc. At the moment we use normal
Qt sliders as controls, so it would be great to reuse your control
widgets.

Maybe you might be interested in our data monitor widgets, as well.
Those widgets are only coupled to a DataSource abstract class (C++), so
they can easily be incorporated into different apps. At the moment we
only have instantaneous (or frame) monitors. X-axis-time monitors are
planted after clam 1.0. So this seems another opportunity to share among
Qt4 based audio apps.

Cheers,
Pau
