QListProxyRo class reference
[Container proxies module]

This class is a member of the QtLua namespace.

This template class may be used to expose an attached QList container object to lua script for read access. The QListProxy class may be used for read/write access.

See QListProxy class documentation for details and examples.

Shortcut for Ref smart pointer class to QListProxyRo type provided for convenience

This virtual function overrides the meta_contains virtual function defined in the UserData base class.

Documentation inherited from base class:

This function returns true if either the ValueBase::OpIndex operation or the ValueBase::OpNewindex operation is supported and an entry is associated to the given key.

The default implementation returns !meta_index(ls, key).is_nil() or false if UserData::meta_index throws.

This virtual function overrides the meta_index virtual function defined in the UserData base class.

Documentation inherited from base class:

This function is called when a table read access operation is attempted on a userdata object. The default implementation throws an error message. The UserData::support function must be reimplemented along with this function to report ValueBase::OpIndex as supported.

Parameters list:

• key: Value used as table index.

The return value is Table access result value.

This virtual function overrides the meta_operation virtual function defined in the UserData base class.

Documentation inherited from base class:

This function is called when a lua operator is used with a UserData object. The default implementation throws an error message. The UserData::support function must be reimplemented along with this function.

Parameters list:

• op: Specify invoked lua operator (see ValueBase::Operation).
• a: First value involved in operation.
• b: Second value involved in operation for binary operators.

The return value is Operation result value.

This virtual function overrides the new_iterator virtual function defined in the UserData base class.

Documentation inherited from base class:

This function may return an Iterator object used to iterate over an userdata object. The default implementation throws an error message. The UserData::support function must be reimplemented along with this function to report ValueBase::OpIterate as supported.

The return value is an Iterator based iterator object.

Attach or detach container. argument may be NULL

This virtual function overrides the support virtual function defined in the UserData base class.

Documentation inherited from base class:

Check given operation support.
