@section{description}
A gui showing the link::Classes/Pdef::'s name, playing state, source state, and envir state. Optionally, its envir can also be edited.
@section{subsection}
First example
@racketblock[
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.close;
g = PdefGui(Pdef(\a), 3); // with an envirgui for 3 items
Pdef(\a).set(\lofreq, [1, 10], \str, "someString", \oops, \oneSymbolTooMany);
Pdef(\a).clear;
Pdef(\a).envir.clear;
g.close;
( // put it in an existing window - margin is 0@0
w = Window("my win", Rect(200, 200, 300, 200)).front;
w.addFlowLayout;
PdefGui(Pdef(\a), 0, w);
PdefGui(Pdef(\a), 3, w);

Details on the GUI elements
@section{definitionList}
## name button
|| when selected, typing the delete key will delete its Pdef.
## play/stop button
|| indicates whether the Pdef is playing:
@section{table}
## " >" || 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.
@section{table}
## "paus" || shown when you can pause it,
## "rsum" || shown when you can resume it.
::
## src button
|| opens a document to edit the source (function) of the Pdef.
@section{table}
## green || a source exists,
## white || 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.
@section{table}
## green || the Pdef has an envir,
## white || the envir is nil.

@section{ClassMethods}
@section{subsection}
Creation Methods
@section{method}
new
Create a new link::Classes/JITGui:: that will be watching an object and display its state.
@section{argument}
object
the object to watch
@section{argument}
numItems
the number of display items to use, e.g. how many fields for text, or how many EZSliders for single-number parameters.
@section{argument}
parent
a parent view on which to display. If nil, a new window is created; strong::parent:: can also be an existing window or a composite view.
@section{argument}
bounds
a desired size and position where to display a JITGui. can be nil, a link::Classes/Point::, or a link::Classes/Rect::. JITGuis know their minimum size ( strong::minSize:: ), and if bounds is nil, minSize is used. if bounds is a link::Classes/Point:: or link::Classes/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.
@section{argument}
makeSkip
A flag whether to make a skipjack.
@section{argument}
options
a list of additional information, e.g. flags about optional buttons. (this is used is some subclasses)
@section{InstanceMethods}
@section{method}
object
a link::Classes/Pdef::, or nil
@section{method}
numItems
the number of items in the envirGui
@section{method}
parent
the parent view
@section{method}
bounds
the bounds of the link::#-zone::
@section{method}
zone
the link::Classes/CompositeView:: within which the PdefGui is shown
@section{method}
nameBut, playBut, pauseBut, srcBut, envBut
the buttons
@section{method}
envirGui
the gui for the Pdef's envir - nil if numItems is 0.
@section{method}
object
put an object in the gui.
@section{method}
moveTo
(if the jitGui is in its own window)
move it to some specific location.
@section{method}
clear
(if the jitGui is in its own window)
set the PdefGui's object to nil
@section{method}
close
(if the jitGui is in its own window)
and close its window.
@section{subsection}
Internal methods
@section{method}
srcString
a compileString that recreates the Pdef.
@racketblock[
// assume g from above is still there
g.srcString;
::
]
@section{method}
editString
a compileString that recreates the Pdef's envir at edKey.
@section{method}
editStrings
a compileString that recreates the Pdef's envir at edKeys.
@section{argument}
edKeys
Default value is nil.
@racketblock[
// assume g from above is still there
g.editString;
Pdef(\a).set(\foo, \bar);
g.editString(\foo);
g.editStrings;
::
]
@section{method}
getUsedKeys
the keys in use in the envir
@racketblock[
g.getUsedKeys;
::
]
@section{method}
openDoc
open a document with some strings at some location
@racketblock[
g.openDoc(g.editStrings);
::
]
@section{method}
makeEnvirGui
make an envirGui within zone - called internally.
