A scrollbar object creates a scroll bar control window. "Minimum" and "Maximum" properties specify the value range of the scroll bar. The property "Steps" gives the number of divisions. Setting "roundIt" to "Yes" results in scroll bar giving out only integer values. If "Execute on change" is set to "Yes" a new thread is created each time the value changed. Setting "Animated" to "Yes" results in creating threads during the user draging the scroll bar. This option is only used when "Exec on change" is "Yes". When running time of the created threads is long this option should be used together with a Thread blocker object.
