3.08 the ScrollSmooth of member

Syntax:
set the ScrollSmooth of member whichcastmember to 0
set x = the ScrollSmooth of member whichcastmember

Purpose:
This property is used to get or set the values for soft scrolling.

The following values are allowed:

• 0: scrolling is not smoothed
• 1: scrolling is smoothed (bezier level 3)
• 2: scrolling is even more smoothed (bezier level 5)

The display is updated with each idle event Director passes to loaded Xtras. As the timing depends on the actual frame rate, smooth scrolling can have unexpected results on slow machines. Therefore it is wise to turn of smooth scrolling on 68k Macintosh computers.

If you like to set the ScrollTop of member property with calls from lingo handlers, for example to create your own scrollbars, make sure the scrolling is finished, before you set a new value. In this case you should temporarily turn off smooth scrolling.

This property can be tested and set.

Notes:

• The default is a value of 2 (smooth scrolling with bezier level 5),
• the value is an integer.
