A progress bar is a control that indicates the progress of a lengthy operation by displaying a colored
bar inside a horizontal rectangle. The length of the bar, in relation to the length of the rectangle,
corresponds to the percentage of the operation that is complete. The progress bar can be created using
the XSIUIToolkit.ProgressBar property. The default minimum and maximum is between 0
and 100 with a step of 1.
Warning: When using the ProgressBar from JScript you must explicitly set the Visible property to false
when the script is done with it. In other languages the ProgressBar automatically removes itself from
the screen as soon as all local variables referring to the ProgressBar object go out of scope.
Note: A progress bar should only be updated a few times a second. If is updated more frequently it can
potentially slow down the script execution. For example, an algorithm scanning 1,000,000 vectors would
be slowed considerably if it updated a progress bar for each vector.
