The CSS functions stateInteractor() and numericInteractor() allow
you to handle symbol interactions in a finer way.
These functions have two optional parameters. The first
parameter is the name of a model attribute that will hold the interaction
values both in read and write modes. The second parameter is the initial
value, in case the model attribute does not yet exist.
If the first parameter is not specified, then an internal
variable is used (actually a property of the graphic object). This
can be useful if you do not want the model to be affected by interactions.
These functions are able to call an
ActionListener when
interaction is performed. To do so, use
addActionListener() on
the function itself. See
addActionListener.
Examples
In the Parameter tab, set the following values to the
interactor parameter (like push_state):
numericInteractor(test,
40): interaction value for a dial or a slider, of
type numeric, that modifies the model attribute test and
defaults to 40 if the model has no value defined for test.
numericInteractor(,
80): interaction value for a dial or a slider, of
type numeric, that does not affect the model and defaults to 80.
stateInteractor(state):
interaction value for a button, of type string, that modifies the
model attribute state. The default value
is given by state.
