See g_param_spec_internal()` for details on the property strings.

method param-spec-expression ( Str $name, Str $nick, Str $blurb, UInt $flags --> N-Object )

• $name; canonical name of the property.

• $nick; a user-readable name for the property.

• $blurb; a user-readable description of the property.

• $flags; flags for the property.

Return value; a newly created property specification.

value-dup-expression

Retrieves the Gnome::Gtk4::Expression stored inside the given value, and acquires a reference to it.

method value-dup-expression ( N-Object $value --> N-Object )

• $value; a Gnome::GObject::N-Value initialized with type GTK_TYPE_EXPRESSION

Return value; a Gnome::Gtk4::Expression.

value-get-expression

Retrieves the Gnome::Gtk4::Expression stored inside the given value.

method value-get-expression ( N-Object $value --> N-Object )

• $value; a Gnome::GObject::N-Value initialized with type GTK_TYPE_EXPRESSION

Return value; a Gnome::Gtk4::Expression.

value-set-expression

Stores the given Gnome::Gtk4::Expression inside value.

The Gnome::GObject::N-Value will acquire a reference to the expression.

method value-set-expression ( N-Object $value, N-Object() $expression )

• $value; a Gnome::GObject::N-Value initialized with type GTK_TYPE_EXPRESSION

• $expression; a Gnome::Gtk4::Expression.

value-take-expression

Stores the given Gnome::Gtk4::Expression inside value.

This function transfers the ownership of the expression to the Gnome::GObject::N-Value.

method value-take-expression ( N-Object $value, N-Object() $expression )

• $value; a Gnome::GObject::N-Value initialized with type GTK_TYPE_EXPRESSION

• $expression; (transfer ownership: full) a Gnome::Gtk4::Expression.
