Javascript user interface and OpenGL graphics


The jsui object is a general purpose user interface object driven by javascript. There are a number of templates already built to use (some of which are shown below). While the patcher is in edit mode, you can ctrl-click (mac) or right-click (pc) to bring up the contextual menu which will let you view and edit the currently loaded javascript file, or select one of the template files from jsui-library. If the javascript file also has a help file associated with it (as do all of the template objects contained in this patch), the associated help file will be loaded instead of jsui.maxhelp. The inspector lets you set the javascript file, javascript arguments, size, border flag, and disable full scene anti-aliasing (fsaa).

At the present time, mouse position and object redrawing will only be reported correctly in the jsui object if the patching and Presentation mode sizes of the object are the same.




bang Invokes the function named bang if defined.
int user-defined [int]
Invokes the function named msg_int if defined.

Invokes the function named msg_float if defined.
list user-defined [list]

autowatch filewatch-flag (1 or 0) [int]
