ScrollBar.getIncrement介绍

[英]Returns the amount that the receiver's value will be modified by when the up/down (or right/left) arrows are pressed.
[中]返回按下上/下（或右/左）箭头时接收器值将被修改的量。

public void controlResized(ControlEvent e) {
    Rectangle clientArea = fScrolledComposite.getClientArea();
    
    ScrollBar verticalBar= fScrolledComposite.getVerticalBar();
    verticalBar.setIncrement(VERTICAL_SCROLL_INCREMENT);
    verticalBar.setPageIncrement(clientArea.height - verticalBar.getIncrement());
    ScrollBar horizontalBar= fScrolledComposite.getHorizontalBar();
    horizontalBar.setIncrement(HORIZONTAL_SCROLL_INCREMENT);
    horizontalBar.setPageIncrement(clientArea.width - horizontalBar.getIncrement());
  }
});
