   23 Functional Details #!N #!N This interactor provides incremental control of various 
   24 functions in a visual program (e.g., the number of contour lines 
   25 currently displayed on an isosurface in the Image window). The integer 
   26 range over which the module acts is governed by its attributes 
   27 (e.g., minimum, maximum, and delta), which in turn are either (1) 
   28 specified by the parameter values in its  #!F-adobe-times-bold-r-normal--18*   Set Attributes... #!EF 
   29 dialog box or (2) determined from input to the module (e.g, 
   30 a data field). In the second case, the interactor is said 
   31 to be "data driven." #!N #!N Note: The interactor is invoked 
   32 by double-clicking on its icon in the VPE window. Its configuration 
   33 dialog box is accessed from the  #!F-adobe-times-bold-r-normal--18*   Edit #!EF pull-down menu 
   34 in the same window. #!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   
   35  #!F-adobe-times-bold-r-normal--18*   data #!EF #!EF #!I50 #!N is the object (usually a 
   36 data field) from which the interactor can derive any or all 
   37 of the minimum, maximum, and delta attributes when the corresponding input 
   38 tabs are up. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   refresh #!EF #!EF 
   39 #!I50 #!N resets the interactor so that the output is computed 
   40 from the current input. If  #!F-adobe-times-bold-r-normal--18*   refresh #!EF = 0 (the 
   41 default), the output is recomputed only if the current output does 
   42 not lie within the range of the current  #!F-adobe-times-bold-r-normal--18*   data #!EF 
   43 . The default for the output of the interactor is the 
   44 midpoint of  #!F-adobe-times-bold-r-normal--18*   min #!EF and  #!F-adobe-times-bold-r-normal--18*   max #!EF . #!N 
   45 #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   min #!EF  #!F-adobe-times-medium-r-normal--18*   and #!EF  #!F-adobe-times-bold-r-normal--18*   max 
   46 #!EF #!EF #!I50 #!N specify the minimum and maximum values of 
   47 the interactor's integer output. If set, these values override those implied 
   48 by  #!F-adobe-times-bold-r-normal--18*   data #!EF . #!N #!N If neither  #!F-adobe-times-bold-r-normal--18*   min 
   49 #!EF nor  #!F-adobe-times-bold-r-normal--18*   data #!EF is specified, the interactor uses the 
   50 minimum set in the  #!F-adobe-times-bold-r-normal--18*   Set Attributes... #!EF dialog box. #!N 
   51 #!N If neither  #!F-adobe-times-bold-r-normal--18*   max #!EF nor  #!F-adobe-times-bold-r-normal--18*   data #!EF is 
   52 specified, the interactor uses the maximum set in the  #!F-adobe-times-bold-r-normal--18*   Set 
   53 Attributes... #!EF dialog box. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   delta #!EF 
   54 #!EF #!I50 #!N specifies a scalar value as a factor for 
   55 calculating the increment between successive outputs over the specified range. The 
   56 actual value depends on the interpretation specified by  #!F-adobe-times-bold-r-normal--18*   method #!EF 
   57 (see below). #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   method #!EF #!EF #!I50 
   58 #!N specifies the interpretation of  #!F-adobe-times-bold-r-normal--18*   delta #!EF : #!N #!I0 
   59 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N o "rounded": the increment ( 
   60  #!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 
   61 #!EF is rounded to a "nice" number. The spacing between successive 
   62 values will approximate the interval specified by  #!F-adobe-times-bold-r-normal--18*   delta #!EF . 
   63 (For example, the default value of 0.01 specifies an interval of 
   64 1/100 of the specified range.) #!N #!I30 #!N o "relative": the 
   65 interpretation is the same as for "rounded," but the increment is 
   66  #!F-adobe-times-medium-i-normal--18*   not #!EF rounded. #!N #!I30 #!N o "absolute":  #!F-adobe-times-bold-r-normal--18*   delta 
   67 #!EF is the absolute value of the interval. (If  #!F-adobe-times-bold-r-normal--18*   delta 
   68 #!EF has not been specified, its default is 1.) #!N #!N 
   69 The default value for  #!F-adobe-times-bold-r-normal--18*   method #!EF depends on other input. 
   70 The default is: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 
   71 - "rounded" if  #!F-adobe-times-bold-r-normal--18*   data #!EF is specified  #!F-adobe-times-medium-i-normal--18*   or #!EF 
   72 if both  #!F-adobe-times-bold-r-normal--18*   min #!EF and  #!F-adobe-times-bold-r-normal--18*   max #!EF are specified. 
   73 #!N #!I30 #!N - "absolute" in all other cases. #!N #!I0

   75  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   label #!EF #!EF #!I50 #!N is the global label 
   76 of all instances of the corresponding interactor stand-in. An interactor instance's 
   77 local label (set from the Control Panel) overrides a global label. 
   78 By default, the global label is set by the user interface.
