Element: group.is_layer

Type

numeric

Description

A numeric value of 1 or 0 indicating whether group is a layer group. A graphic primitive can be a member of many groups, but only one of these groups can be a layer group. If an attempt is made to add a primitive to a layer group while it is already a member of another layer group, it is removed from the other layer group first.

A group's layer status can be changed by assigning the appropriate boolean value to this element.
