包路径：org.eclipse.swt.widgets.ScrollBar
类名称：ScrollBar
方法名：setThumb

ScrollBar.setThumb介绍

[英]Sets the thumb value. The thumb value should be used to represent the size of the visual portion of the current range. This value is usually the same as the page increment value.

This new value will be ignored if it is less than one, and will be clamped if it exceeds the receiver's current range.
[中]设置拇指值。thumb值应用于表示当前范围的可视部分的大小。该值通常与页面增量值相同。
如果这个新值小于1，它将被忽略，如果它超过接收器的当前范围，它将被钳制。
