7 EnvirGui displays all keys and values of an environment, so one can change them flexibly. Single number get displayed with an link::Classes/EZSlider::, pairs of numbers with an link::Classes/EZRanger::, and anything else is shown as an link::Classes/EZText:: (a text field).
18 g = EnvirGui.new(nil, 5); // empty with 5 slots
19 g.object_((a: 1, b: \werty, freq: [500, 2000])); // put some things in
20 g.envir.put(\karl, \otto1); // one more
21 g.envir.putAll((b: -12, r: 1, s: 2, t: 3, u: 4, v: 5))
23 g.object_((x: 2)); // put something else in
25 g.envir.putAll((b: -12, r: 1, s: 2, t: 3, u: 4, v: 5))
41 the number of items to display. If an envir is given, and no num, num is envir.size.
44 the parent view to display in; if none is given, a new window is created.
47 the bounds within which to display; if none is given, bounds are calculated.
50 flag whether to make a skipjack to manage updates of the envirgui.
57 subsection::Instance Variables
60 how many envir items to display
63 the envir displayed - actually an alias for object.
66 the composite view the envirgui makes for itself
69 the areas in which the key-value pairs are displayed.
72 the EZGuis that display the values:
74 ## Single numbers will have an link::Classes/EZSlider::,
75 ## pairs of numbers will be shown as an link::Classes/EZRanger::,
76 ## all other values are shown as compileStrings in an link::Classes/EZText::.
80 EZSlider and EZRanger needs specs for their display ranges; if there is a global spec for that key (key.asSpec), it will be used. If not, a spec is generated (see the link::#-getSpec:: method) and kept in these (local) specs.
83 if the size of envir exceeds numItems, the keys displayed can be rotated: e.g. with 10 keys displayed on 5 valFields, keysRotation 0 means show keys (0..4), keysRotation 2 means show keys (2..6), etc.
85 subsection::Some Methods
88 set the environment to show
91 can be nil, a dictionary, an environment, or an event.
94 g = EnvirGui((freq: 120, \amp: 0.2, \pan: -0.5), 12, nil, bounds: Rect(20, 400, 220, 100));
95 g.object_((a: 1, b: [2, 3], c: \symbol, d: [4, 5, 6], f: { "boing".postln }))
102 if in its own window, set the window's name
109 For editing, specs for the parameter ranges are needed. These can be set locally in the EnvirGui, or global specs will be looked up. If no local or global specs exist for that parameter name, getSpec makes a usable guess for them.
114 g.getSpec(\freq, 400); // \freq exists as global spec, so use that
115 g.object_((freq: 150));
117 g.getSpec(\iFrek, 500); // no global spec, so make a new one:
118 // exponential from val * 0.05 to val * 20;
119 g.specs; // and keep it here
120 g.envir.put(\iFrek, 500);
124 the parameter name for which to find a spec
127 the current value of that param, which may be used for guessing specs.
130 add a spec for a given key, or (if it is a global key) override a global spec with a local one:
133 g.putSpec(\iFrek, [10, 1000, \exp]);
134 g.putSpec(\freq, [100, 1000, \exp]);
135 g.object_((freq: 200, iFrek: 20));
138 subsection::Some internal methods
141 set a field by index, with the new key, value;
153 means the field had the same key already.
156 update the widgets for the current keys
159 remove the link::Classes/EZGui:: at this index
162 remove all unused EZGuis
167 // Setting envir variables in a Tdef:
169 Tdef(\text).set(\note, [0, 2, 7], \dur, { [0.1, 0.2, 0.4].choose }, \pan, 0, \amp, 0.1);
171 w = Window("EZTexts", Rect(200, 400, 304, 120)).front;
174 TdefGui(Tdef(\text), 0, parent: w);
176 e = EnvirGui(Tdef(\text).envir, 4, parent: w);
182 (note: ev.note, dur: mydur, amp: ev.amp, pan: ev.pan).postln.play;
188 // or equivalently, use the built-in EnvirGui in TdefGui:
189 TdefGui(Tdef(\text), 4);
191 Tdef(\text).set(\yuhu, Prand([2, 3, 5, 8, 13], inf), \magic, [\abra, \cadabra]);
