TITLE:: ParamView
summary:: show a parameter of a JITLib process
categories:: JITLib
related:: Classes/JITGui, Overviews/JITLib
DESCRIPTION::
ParamView displays a parameter value, and switches representation as appropriate for value: A single number is shown by an EZSlider, a pair of numbers by an EZRanger, and anything else as code on an EZText.
First examples:
code::
w = Window("test", Rect(20, 820, 400, 100)).front;
w.addFlowLayout;
~pv = ParamView(w, Rect(20, 20, 360, 20));
~pv2 = ParamView(w, Rect(20, 20, 360, 40));
// not working properly yet
~pv.bounds_(Rect(4, 4, 300, 40));
~pv.dump
~pv.viewType_(0); // EZNumber
~pv.viewType_(1); // EZRanger
~pv.viewType_(2); // EZText
~pv.label_(\freq);
~pv.spec_(\freq); // needs spec for EZSlider
~pv.value_(200);
~pv.value_(2000);
// switches to EZRanger
~pv.value_([200, 2000]);
// 3 numbers -> switches to EZText
~pv.value_([20, 200, 2000]);
// anything else -> EZText
~pv.value_(\blonk);
~pv.action = { |pv| pv.value.postcs };
