Classes | JITLib > GUI | Live Coding


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


A gui showing the Pdef's name, playing state, source state, and envir state. Optionally, its envir can also be edited.

First example

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"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.
greena source exists,
whitethe 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.
greenthe Pdef has an envir,
whitethe envir is nil.

Class Methods

Creation Methods


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



the object to watch


the number of display items to use, e.g. how many fields for text, or how many EZSliders for single-number parameters.


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.


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.


A flag whether to make a skipjack.


a list of additional information, e.g. flags about optional buttons. (this is used is some subclasses)

Inherited class methods

Instance Methods


a Pdef, or nil


the number of items in the envirGui


the parent view


the bounds of the -zone


the CompositeView within which the PdefGui is shown






the buttons


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


put an object in the gui.


(if the jitGui is in its own window)

move it to some specific location.


(if the jitGui is in its own window)

set the PdefGui's object to nil


(if the jitGui is in its own window)

and close its window.

Internal methods


a compileString that recreates the Pdef.


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


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



Default value is nil.


the keys in use in the envir


open a document with some strings at some location


make an envirGui within zone - called internally.
