Maybe a widget not included on the container layout but with sizes and position depending on the slider's ones. > What about starting a Qt-library with some nice faders/sliders and knobs? Some of this is what we have started on the CLAM project. We are gathering some of the best GPL Qt audio related widgets around [1] into a Qt designer plugin so you can use all of them on CLAM prototypes, but also we would be delighted if that becomes a comunity effort not bound to CLAM. If fact, most of the widgets have no real dependencies on CLAM. [1] http://clam.iua.upf.edu/wikis/clam/index.php/Development_screenshots The plugin currently includes: - CLAM realtime data visualization widgets (oscilloscope, bargraph, vumeter, keyspace, tonnetz...), and a ControlSurface widget (controls/visualizes a pair of parameters to explore by moving a point in a surface). - Pksampler povray based widgets but ported to C++ and with properties to configure the pixmap collection [2] - Rosegarden/QSynth knobs but with QGradient based drawing. Also with properties to configure the color and mouse interaction (linear vs radial) [3] -- David García Garzón (Work) dgarcia at iua dot upf anotherdot es http://www.iua.upf.edu/~dgarcia
