The progress bar control com.sun.star.awt.UnoControlProgressBar displays a growing or shrinking bar to give the user feedback during a persisting task. The minimum and the maximum progress value of the control is set by the ProgressValueMin and the ProgressValueMax properties of the control model that supports the service com.sun.star.awt.UnoControlProgressBarModel . The progress value is controlled by the ProgressValue property. The fill color can be changed by setting the property FillColor. The control implements the interface com.sun.star.awt.XProgressBar which allows you to control the progress bar. The progress bar interface com.sun.star.awt.XReschedule helps to update and repaint the progress bar while a concurrent task is running, but this interface interrupts the main thread of the office. Issue https://www.openoffice.org/issues/show_bug.cgi?id=i71425 is assigned to find an appropriate solution for this problem.
