Use Style to get and set how progress is illustrated by the TProgressBar. Style is set using the TProgressBarStyle enumeration, which has the values pbstNormal and pbstMarquee. pbstNormal displays the percentage of completion by the position of the highlighted portion of the bar. Zero percentage completion is to the far left, 100% completion to the far right. pbstMarquee indicates that progress is occuring by moving the highlighted portion back and forth through the entire range of the bar.
