Scrollbar.setVisibleAmount

Class Overview | Class Members | This Package | All Packages

Syntax

public synchronized void setVisibleAmount( int newAmount )

Parameters

newAmount: the amount visible per page.

Description

Sets the visible amount of this scroll bar.

The visible amount of a scroll bar is the range of values represented by the width of the scroll bar's bubble. It is used to determine the scroll bar's block increment.

Normally, a program should change a scroll bar's value only by calling setValues. The setValues method simultaneously and synchronously sets the minimum, maximum, visible amount, and value properties of a scroll bar, so that they are mutually consistent.
