Message System Manual

Send and receive messages to react to system events, actions on scene elements and events in user interfaces.

Overview

Messages are a core principal of the classic API of Cinema 4D and fulfill an event-like purpose. Various interfaces in the classic API have methods attached to them which are linked to the message system. A message is always denoted by an identifier, e.g., MSG_DESCRIPTION_EDIT_ENTRY, which does signify the message event to the object it is being send to. Messages can also be accompanied by ingoing or outgoing message data which does qualify that event. This message data can consist out of multiple elements and is usually wrapped as a dictionary in the Python API.

The message data that is related to a message can be treated in an in- or outgoing fashion or both. The message MSG_DESCRIPTION_EDIT_ENTRY will be broadcasted with a dictionary containing the DescID for the element which did raise that message. Attempting to modify this DescID or returning modified message data will have no effect on the DescID of the raising element, the data is only ingoing. Other message events will however explicitly being sent with the intent that the recipient does modify or complement the data. MSG_GETCUSTOMICON for example is being sent so that a NodeData.Message() instance can return a specific icon for the associated node with the returned message data.

Technical Overview

There are three major categories of messages in Cinema 4D: Core messages, messages to scene elements, and messages to dialogs and custom interface elements. Message to C4DAtom instances, e.g., objects, tags, or other scene elements, are being sent with C4DAtom.Message(). When the message identifier sent to an atom is being supported by the atom type and the message data is well formed, then the message will invoke a certain action in the atom as documented by the message symbols below. Sending MSG_UPDATE to a PointObject will for example force a point object to update all its internal data that does rely on the vertices of the point object. The handling of messages sent to C4DAtom instances plays a fundamental role when implementing plugin interfaces, e.g., c4d.ObjectData, c4d.TagData or c4d.ShaderData. Listening for MSG_DESCRIPTION_COMMAND in the Message method of an ObjectData interface will allow for example to react on button clicks in the description interface of the corresponding BaseObject instances of that type.

Core messages are a message category that is related to global system wide events; as opposed to the messages sent to C4DAtom instances which only affect a single atom. Core messages can be invoked among other functions with c4d.SendCoreMessage() and c4d.GeSyncMessage() and received with MessageData, GeDialog and GeUserArea instances by overwriting their CoreMessage methods. Core messages convey broad events as for example enforcing redraw event or reacting on the modification of the active document.

A third category of messages is received by GeDialog and GeUserArea instances in their Message methods. The messages received here differ from those broadcasted to the Message methods of C4DAtom instances. These messages only rarely have to be sent by users and instead are primarily intended to react to events in the respective user interface, e.g., a mouse or key press event. These messages also do play an important role in the execution of the event loop of such GUI elements, e.g., sending BFM_DRAW to a GeUserArea instance will cause its GeUserArea.DrawMsg() being called.
