#!F-adobe-helvetica-medium-r-normal--18* #!N #!CDarkGreen #!N #!Rsetatdb Setting Interactor Attributes #!N #!EC #!N #!N You can have several instances of the same interactor. Each instance can be a different style (stepper, dial, or slider) and can have a different increment value. However, all instances of an interactor have the same value and the same minimum and maximum limits. As you change the value or range of one instance, the other instances of that interactor are automatically updated. #!N #!N To change the #!F-adobe-times-medium-i-normal--18* range #!EF of values of an interactor, select the interactor, and select the #!F-adobe-times-bold-r-normal--18* Set Attributes... #!EF option in the #!F-adobe-times-bold-r-normal--18* Edit #!EF menu; or double-click on the interactor in the Control Panel. The #!F-adobe-times-bold-r-normal--18* Set Attributes... #!EF dialog box ( #!Lsetlim80,dxall397 f Figure 80 #!EL ) appears. #!N #!N #!Cbrown #!F-adobe-times-medium-r-normal--18* #!Rsetlim80 #!N Graphics omitted from Online Documentation.

Set Attributes Dialog Box #!EF #!N #!EC In this box you can: #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N o Set maximum and minimum values. #!N #!I30 #!N o Change the step increment. #!N #!I30 #!N o Change the number of decimal places displayed. (In the case of an integer interactor, the decimal place field is disabled.) #!N #!I30 #!N o Choose whether to update the image continuously as you change the interactor values, or to update only when the mouse button is released. This applies only when #!F-adobe-times-bold-r-normal--18* Execute on Change #!EF is enabled. Note: Many interactor types can also be data-driven, meaning that their attributes are derived at run time from data in the visual program. See #!Lddinter,dxall434 h Using Data-Driven Interactors #!EL . #!N #!I0 #!N #!EF #!N The increment and update options can be applied to the either just the current instance or to all instances of the interactor. To affect all instances, click on the option box for the attribute you want to set (increment or update), and select the Global option from option menu. To affect only the current instance, select the Local option. Having multiple instances of an interactor with different increments allows coarse and fine controls. For example, you may want one instance of a scalar interactor to change by increments of 1.0, another instance by 0.10, and a third instance by 0.01. Note that the "global" option will not override interactors which have been explicitly set to "local." #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Ltall399,dxall399 h Vector interactors #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
