Methods

new

:native-object

Create a Menu object using a native object from elsewhere. See also Gnome::N::TopLevelClassSupport.

multi method new ( N-GObject :$native-object! )

attribute-iter-get-name

Gets the name of the attribute at the current iterator position, as a string.

The iterator is not advanced.

Returns: the name of the attribute

method attribute-iter-get-name ( --> Str )

attribute-iter-get-next

This function combines attribute-iter-next() with attribute-iter-get-name() and attribute-iter-get-value().

First the iterator is advanced to the next (possibly first) attribute. If that fails, then False is returned and there are no other effects.

If successful, name and value are set to the name and value of the attribute that has just been advanced to. At this point,attribute-iter-get-name() and attribute-iter-get-value() will return the same values again.

The value returned in name remains valid for as long as the iterator remains at the current position. The value returned in value must be unreffed using g-variant-unref() when it is no longer in use.

Returns: True on success, or False if there is no additional attribute

method attribute-iter-get-next (
  CArray[Str] $out_name, N-GObject $value
  --> Int
)

  • CArray[Str] $out_name; (out) (optional) (transfer none): the type of the attribute

  • N-GObject $value; (out) (optional) (transfer full): the attribute value

attribute-iter-get-value

Gets the value of the attribute at the current iterator position.

The iterator is not advanced.

Returns: (transfer full): the value of the current attribute

method attribute-iter-get-value ( --> N-GObject )

attribute-iter-next

Attempts to advance the iterator to the next (possibly first) attribute.

True is returned on success, or False if there are no more attributes.

You must call this function when you first acquire the iterator to advance it to the first attribute (and determine if the first attribute exists at all).

Returns: True on success, or False when there are no more attributes

method attribute-iter-next ( --> Int )
