Trait containing all MenuLinkIter methods.

Implementors

MenuLinkIter

Required methods

`fn get_name(&self) -> Option<GString>`

Gets the name of the link at the current iterator position.

The iterator is not advanced.

Returns

the type of the link

`fn get_next(&self) -> Option<(GString, MenuModel)>`

This function combines MenuLinkIterExt::next with MenuLinkIterExt::get_name and MenuLinkIterExt::get_value.

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

If successful, out_link and value are set to the name and MenuModel of the link that has just been advanced to. At this point, MenuLinkIterExt::get_name and MenuLinkIterExt::get_value will return the same values again.

The value returned in out_link remains valid for as long as the iterator remains at the current position. The value returned in value must be unreffed using gobject::ObjectExt::unref when it is no longer in use.
