thumbSize

Type

property

Summary

Specifies how large a scrollbar's draggable thumb is.

Syntax

set the thumbSize of <scrollbar> to <number>

Description

Use the thumbSize property to specify the size of a scrollbar's draggable thumb.

Normally, the thumbSize is proportional to the proportion of content visible on the screen. For example, if a third of the content can be seen and the rest is always scrolled off, the scrollbar thumb should cover a third of the scrollbar area, so the number should be one-third of the difference between the scrollbar's startValue and its endValue.

If the proportionalThumbs property is set to false, this property has no effect.

Examples

set the thumbSize of scrollbar "Contents Group" to 500

set the thumbSize of scrollbar 1 to \
   (the height of group "Main"/the formattedHeight of group "Main")
