Remarks
Scroll bars have a marker, called a thumb, which can be dragged up and down (or left and right) within a range of values. The thumb can be dragged to different positions on the scroll bar, or it can step up or down in blocks or units.
GUI scroll bars automatically maintain block and unit operations. When a block or unit operation takes place, a ScrollEvent is generated with both the actual thumb position and the position the thumb would assume if the scroll bar is updated. The block and unit amounts are added or subtracted from the current position according to the scroll type that occurs.
By default, a scroll bar has a range of (0,99), a unit size of 1, a block size of 10, and an initial thumb position of 0.
