Description

Represents the base class for all messages.

TMessage represents the base class used for message purposes. It can be inherited in order to send custom messages.

Warning: For C++ projects, use TMessageBase instead.

Using Objects as Contents

The contents of a TMessage can be of any type, including classes. However, when you create a TMessage with an object as value, TMessage does not take ownership of the object; you must delete the object yourself, and ensure that the message has been deleted first. TObjectMessage, a subclass of TMessage, allows messages to take ownership of their contents.
