Struct pango::Attribute

pub struct Attribute { /* private fields */ }

The Attribute structure represents the common portions of all attributes.

Particular types of attributes include this structure as their initial portion. The common portion of the attribute holds the range to which the value in the type-specific part of the attribute applies and should be initialized using Pango::Attribute::init(). By default, an attribute will have an all-inclusive range of [0,G_MAXUINT].

Implementations
