Required Methods§
sourcefn next(&self) -> Option<(GString, Variant)>
fn next(&self) -> Option<(GString, Variant)>
This function combines g_menu_attribute_iter_next()
with
g_menu_attribute_iter_get_name()
and g_menu_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,
g_menu_attribute_iter_get_name()
and g_menu_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
out_name
the type of the attribute
value
the attribute value
