pvar

Connect to a named object in a patcher

Description

The pvar object lets you build user interfaces in one part of your patcher that are associated with the "process" part in another part of the patcher. Unlike the send and receive objects, pvar does not work globally; the pvar object and its associated object must be in the same patcher. To set an object's name, select the object, open the inspector, then enter a name under Name > Scripting Name. The name cannot be a number, although it can contain numbers.

Arguments

object-name[symbol]
optional

The first argument specifies the name of the object to which pvar will be associated with. If no name is supplied, the setname message can be used to connect later.

number-of-outlets[int]
optional

The second argument specifies the number of outlets pvar will have. pvar connects to as many outlets as its associated object has, unless it is more than the number you specify as an argument. The default number of outlets is 1.

Attributes
