PdefGui a line of editing controls for a Pdef, and optionally its envir.

Inherits from: JITGui: TaskProxyGui (like TdefGui)

A gui showing the Pdef's name, playing state, source state, and envir state. 

Optionally, its envir can also be edited.

See also PdefAllGui, TdefGui, TdefAllGui.

First example:

g = PdefGui(); // make a PdefGui 

g.object = Pdef(\a); // show when a Pdef is put in

Pdef(\a, Pbind(\note, 12)); // show whether it has a source

Pdef(\a).play; // show whether playing, stopped, or ended, and pausable

Pdef(\a).set(\dur, 0.25); // show whether the Pdef has an envir


g = PdefGui(Pdef(\a), 3); // with an envirgui for 3 items

Pdef(\a).set(\lofreq, [1, 10], \str, "someString", \oops, \oneSymbolTooMany);




( // put it in an existing window - margin is 0@0

w = Window("my win", Rect(200, 200, 300, 200)).front; 


PdefGui(Pdef(\a), 0, w);

PdefGui(Pdef(\a), 3, w);


Details on the GUI elements:

name button: 

when selected, typing the delete key will delete its Pdef.

play/stop button : 

indicates whether the Pdef is playing: 

" >"  if stopped, 

" _" if playing and active, 

" |" if it is playing, but the stream has ended. 

pause/resume button: 

only visible if one can pause or resume the Pdef, i.e. while it is playing.

"paus" is shown when you can pause it,

"rsum" is shown when you can resume it.

src button: 

opens a document to edit the source (function) of the Pdef.

green if a source exists, white if the source is nil.

env button: 

opens a document to edit the environment of the Pdef, 

which is where one can keep all variables the Pdef uses

for easy access.

green if the Pdef has an envir, white if the envir is nil.

Creation Methods

*new (object, numItems, parent, bounds, extras, makeSkip)

Create a new JITGui that will be watching an object and display its state.

object - the object to watch 

numItems - the number of display items to use, e.g. how many fields for text, 

or how many EZSliders for single-number parameters.

parent - a parent view on which to display. If nil, a new window is created;

parent can also be an existing window or a composite view.

bounds - a desired size and position where to display a JITGui. can be nil, 

a point, or a rect. JITGuis know their minimum size (minSize), 

and if bounds is nil, minSize is used.

if bounds is a point or rect, it will be set to at least minSize.

With a rect one can also supply a position where to display.

If a point,shown size is the maximum of bounds and minSize 

extras - a list of additional information, e.g. flags about optional buttons.

(this is used is some subclasses)

makeSkip - A flag whether to make a skipjack.

Pdef(\a, Pbind(\freq, Prand((1..16) * 55, inf)));


t = PdefGui(Pdef(\a), 4);

Pdef(\a).set(\dur, 0.125, \amp, 0.05);








w = Window("put it in a selfmade window").front;


w.view.decorator.shift(50, 50);

PdefGui(Pdef(\a), 12, w);


Pdef(\b,  Pbind(\note, Pxrand((0..7), inf), \dur, 0.125));

Instance Variables

object a Pdef, or nil

numItems the number of items in the envirGui 

parent, the parent view 

bounds the bounds of the zone

zone the CompositeView within which the TdfGui is shown

nameBut, playBut, pauseBut, srcBut, envBut the buttons

envirGui the gui for the Pdef's envir - nil if numItems is 0.

Instance Methods

object_ (obj) put an object in the gui. 

// if the jitGui is in its own window, you can:

moveTo (h, v) move it to some specific location.

clear set the PdefGui's object to nil

close and close its window.

Internal methods:

srcString a compileString that recreates the Pdef. 

// assume g from above is still there


editString (edKey) a compileString that recreates the Pdef's envir at edKey. 

editStrings (edKeys) a compileString that recreates the Pdef's envir at edKeys.

Short prose description of method.

edKey - Explanation of edKey. Default value is nil. Other information.

// assume g from above is still there


Pdef(\a).set(\foo, \bar);



getUsedKeys the keys in use in the envir


openDoc (strings, bounds)  open a document with some strings at some location


makeEnvirGui make an envirGui within zone - called internally.
