ProportionalThumb Property

Specifies whether the size of the scroll box is proportional to the scrolling region or fixed.

Syntax

object.ProportionalThumb [= Boolean]

The ProportionalThumb property syntax has these parts:

Part	Description
object	Required. A valid object.
Boolean	Optional. Whether the scroll box is proportional or fixed.

Settings

The settings for Boolean are:

Value	Description
True	The scroll box is proportional in size to the scrolling region (default).
False	The scroll box is a fixed size.

Remarks

The size of a proportional scroll box graphically represents the percentage of the object that is visible in the window. For example, if 75 percent of an object is visible, the scroll box covers three-fourths of the scrolling region in the scroll bar.

If the scroll box is a fixed size, the system determines its size based on the height and width of the scroll bar.
