#!N #!N Functional Details #!N #!N This interactor allows the user
to interactively change a list of scalar values. The range over
which the module acts is governed by its attributes (e.g., minimum,
maximum, and delta), which in turn are either (1) specified by
the parameter values in its #!F-adobe-times-bold-r-normal--18* Set Attributes... #!EF dialog box
or (2) determined from input to the module (e.g., a data
field). In the second case, the interactor is said to be
"data driven." #!N #!N If an interactor is not data-driven, its
attributes are taken from its #!F-adobe-times-bold-r-normal--18* Set Attributes... #!EF dialog box
(accessed from the #!F-adobe-times-bold-r-normal--18* Edit #!EF pull-down menu in the Control
Panel). #!N #!N Because the module is interactive, the user can
change the current controlling value directly in the control panel. Note:
The module's control panel is invoked by double-clicking on its icon
in the VPE window. Its configuration dialog box is accessed from
the #!F-adobe-times-bold-r-normal--18* Edit #!EF pull-down menu in the same window. #!N
#!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* data #!EF #!EF #!I50
#!N is the object (usually a data field) from which the
interactor can derive any or all of the minimum, maximum, and
delta attributes when the corresponding input tabs are up. #!N #!I0
#!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* refresh #!EF #!EF #!I50 #!N resets the interactor
so that the output is computed from the current input. If
#!F-adobe-times-bold-r-normal--18* refresh #!EF = 0 (the default), the output is recomputed
only if the current output does not lie within the range
of the current #!F-adobe-times-bold-r-normal--18* data #!EF . #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18*
#!F-adobe-times-bold-r-normal--18* min #!EF and #!F-adobe-times-bold-r-normal--18* max #!EF #!EF #!I50 #!N specify
the minimum and maximum values of the interactor's scalar output. If
set, these values override those implied by #!F-adobe-times-bold-r-normal--18* data #!EF .
#!N #!N If neither #!F-adobe-times-bold-r-normal--18* min #!EF nor #!F-adobe-times-bold-r-normal--18* data #!EF
is specified, the interactor uses the minimum set in the #!F-adobe-times-bold-r-normal--18*
Set Attributes... #!EF dialog box. #!N #!N If neither #!F-adobe-times-bold-r-normal--18* max
#!EF nor #!F-adobe-times-bold-r-normal--18* data #!EF is specified, the interactor uses the
maximum in the #!F-adobe-times-bold-r-normal--18* Set Attributes... #!EF dialog box. This value
overrides the value implied by #!F-adobe-times-bold-r-normal--18* data #!EF . #!N #!I0
#!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* delta #!EF #!EF #!I50 #!N specifies a scalar
value as a factor for calculating the increment between successive outputs
over the specified range. The actual value depends on the interpretation
specified by #!F-adobe-times-bold-r-normal--18* method #!EF (see below). #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18*
#!F-adobe-times-bold-r-normal--18* method #!EF #!EF #!I50 #!N specifies the interpretation of #!F-adobe-times-bold-r-normal--18*
delta #!EF : #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N
o "rounded": the increment ( #!F-adobe-times-bold-r-normal--18* max #!EF - #!F-adobe-times-bold-r-normal--18* min
#!EF ) * #!F-adobe-times-bold-r-normal--18* delta #!EF is rounded to a "nice"
number. The spacing between successive values will approximate the interval specified
by #!F-adobe-times-bold-r-normal--18* delta #!EF . (For example, the default value of
0.01 specifies an interval of 1/100 of the specified range.) #!N
#!I30 #!N o "relative": the interpretation is the same as for
"rounded," but the increment is #!F-adobe-times-medium-i-normal--18* not #!EF rounded. #!N #!I30
#!N o "absolute": #!F-adobe-times-bold-r-normal--18* delta #!EF is the absolute value of
the interval. (If #!F-adobe-times-bold-r-normal--18* delta #!EF has not been specified, its
default is 1.) #!N #!N The default value for #!F-adobe-times-bold-r-normal--18* method
#!EF depends on other input. The default is: #!N #!I0 #!N
#!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N - "rounded" if #!F-adobe-times-bold-r-normal--18* data #!EF
is specified #!F-adobe-times-medium-i-normal--18* or #!EF if both #!F-adobe-times-bold-r-normal--18* min #!EF and
#!F-adobe-times-bold-r-normal--18* max #!EF are specified. #!N #!I30 #!N - "absolute" in
all other cases. #!N #!I0 #!N #!EF #!N #!N #!I0 #!N
#!EF #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* decimals #!EF #!EF #!I50
#!N specifies the number of decimal places displayed in the interactor.
If neither #!F-adobe-times-bold-r-normal--18* data #!EF nor #!F-adobe-times-bold-r-normal--18* delta #!EF is specified,
the interactor uses the value in its own #!F-adobe-times-bold-r-normal--18* Set Attributes...
#!EF dialog box. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* nitems #!EF #!EF
#!I50 #!N specifies the number of items in the interactor list.
These are evenly spaced between the minimum and maximum values (see
above). For example, if this parameter is given a value of
5, and the range is 0-100, the output list will be
{0, 25, 50, 75, 100 }. Note: If #!F-adobe-times-bold-r-normal--18* nitems #!EF
changes, a new list is computed. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18*
label #!EF #!EF #!I50 #!N is the global label of all
instances of the corresponding interactor stand-in. An interactor instance's local label
(set from the Control Panel) overrides a global label. If not
specified, the global label is set by the user interface. #!I0
