[JSup domains|Shared/user domains] e [JSup graphic windows|graphic windows] contain scripts that can be condition/timed/trigger executed.

To edit [JSup domains|domain] code you have to access to the [JSup Application properties|Application properties dialog] and then click on one of the button ''Edit Shared/User code''.

To edit the code of a [JSup graphic windows|graphic window] you have to open the [JSup Window property dialog|Window property dialog] (menu ''Window / Window properties'').

There are different kind of code.
== Active codes ==
These codes are executed on some condition and can be used to initialize, clear, update some tag or other actions.
==== Domain ====
For [JSup domains|domain] they are:
 * '''Shared''' domain:
  * '''On startup''': executed when JSup system start in runtime.
  * '''While active''': executed (at the given ms interval) when the JSup system is active.
  * '''On shutdown''': executed just before a normal JSup system shutdown.
 * '''User''' domain (in a [JSup Multiuser support|multiuser environment] every client has its own user domain code):
  * '''On startup''': executed when the user interface is started.
  * '''While active''': executed (at the given ms interval) while the user interface is active.
  * '''On shutdown''': executed just before a normal shutdown of the user interface.
==== Window ====
In the [JSup graphic windows|graphic window] they are:
 * '''Show code''' (code whose execution is determined by the condition ''the window is visible''):
  * '''On show''': called before activating the animations of the window graphic object.
  * '''While showing''': executed (at the given ms interval) while the windows is shown.
  * '''On hide''': called before deactivating the animations of the window graphic objects.
 * '''Active code''' (code whose execution is determined by the condition ''the window is the active one'', within the JSup graphic interface... or ''has the focus''):
  * '''On active''': executed when the window get the focus.
  * '''While active''': executed (at the given ms interval) while the window has the focus.
  * '''On deactivate''': executed when the window loose the focus.
== Conditions ==
Many [JSup Condition scripts|condition scripts] can be defined to react to a lot of different situations.
== Triggered/Timed ==
[JSup Timed and triggered scripts|Timed /triggered scripts] are executed when some tag change its value or when an interval time has elapsed.
== JavaCode functions ==
[JavaCode functions] are utility function that can used by other [JavaCode|JavaCodes] or [JSup Math code|Math code] within the scope of the container (the [JSup domains|domain] of the [JSup graphic windows|graphic window]).
== Key code ==
Not in the [JSup domains|shared domain].
[JSup Key codes|Key codes] are script that will be invoked when the given key combination is pressed.
For [JSup graphic windows|graphic window] [JSup Key codes|key codes] the action is performed only if the window is showed when the key is pressed.
== JavaCode common ==
A place where to define global (static) variable/object to be used by [JavaCode|JavaCodes] within the scope of the container.
See [JavaCode functions] for better way to define static variable to be used by your code in more exportable/importable way.
