class Gdk::Atom

Gdk::Atom is an opaque type representing a string as an index into a table of strings on the X server

Each window under X can have any number of associated properties attached to it. Properties are arbitrary chunks of data identified by atoms. (An atom is a numeric index into a string table on the X server. They are used to transfer strings efficiently between clients without having to transfer the entire string.) A property has an associated type, which is also identified using an atom.

    • Gdk::Atom

Gdk::Atom.new(atom)

Creates a new Gdk::Atom.

• atom: an Atom value(Integer)
• Returns: a new Gdk::Atom

Gdk::Atom.intern(atom_name, only_if_exists)

Finds or creates an atom corresponding to a given string.

• atom_name: a string.
• only_if_exists: if true, do not create a new atom, but just return the atom if it already exists.
• Returns: the atom corresponding to atom_name, or, if only_if_exists is true, and an atom does not already exists for the string, Gdk::Atom::NONE. Currently, the flag is ignored, since checking the existance of an atom is as expensive as creating it.
• Returns: self

==(other)

Checks if two atoms are equal.

• Returns: true if two atoms are equal.

name

Determines the string corresponding to an atom.

• Returns: a string corresponding to atom.

to_i
