Macro Definition Documentation

§ MSG_POINTS_CHANGED

#define MSG_POINTS_CHANGED

The points have changed. The corresponding data is VariableChanged.

§ MSG_POLYGONS_CHANGED

#define MSG_POLYGONS_CHANGED

The polygons have changed. The corresponding data is VariableChanged.

§ MSG_UPDATE

#define MSG_UPDATE

Must be sent if the bounding box has to be recalculated. (Otherwise use MSG_CHANGE.)

§ MSG_SMALLUPDATE

#define MSG_SMALLUPDATE

Part of the object has changed that needs no cache rebuilding.

Note
This message should be used very carefully, it is there for (small) performance enhancements, for example if a polygon selection is changed then the caches do not need to be rebuilt, so MSG_SMALLUPDATE can be sent.

§ MSG_CHANGE

#define MSG_CHANGE

Must be sent if any object data (except for the matrix) has been changed.

Note
For tag parameter changes call instead of

§ MSG_BASECONTAINER

#define MSG_BASECONTAINER

Message with a container, for example from a C.O.F.F.E.E. plugin. The corresponding data is BaseContainer.

§ MSG_SEGMENTS_CHANGED

#define MSG_SEGMENTS_CHANGED

The segments have changed. The corresponding data is VariableChanged.

§ MSG_FILTER

#define MSG_FILTER

Return true to let the message pass and false to block it.

A message filter that lets block C4DAtom::MultiMessage() calls. The corresponding data is MessageFilter.

§ MSG_TRANSFERGOALS

#define MSG_TRANSFERGOALS

Internal message. Private.

§ MSG_DESCRIPTION_INITUNDO

#define MSG_DESCRIPTION_INITUNDO

Allows elements to create undo actions for the following parameter changes in the attributes manager. This is already automatically handled for keys, tags, objects etc. The corresponding data is DescriptionInitUndo.

§ MSG_DESCRIPTION_CHECKUPDATE

#define MSG_DESCRIPTION_CHECKUPDATE

Allows elements to determine the type of refresh after a parameter has been changed in the Active manager. This is already automatically handled for keys, tags, objects etc. The corresponding data is DescriptionCheckUpdate.

Note
Currently this message is completely handled by all base data classes.
Most plugins will not need to modify the message data. It is more interesting to start some update action - e.g. deleting data that will be rebuilt with the next access.

§ MSG_DESCRIPTION_COMMAND

#define MSG_DESCRIPTION_COMMAND

Sent by for example BUTTON description element. The corresponding data is DescriptionCommand.

§ MSG_DESCRIPTION_POPUP

#define MSG_DESCRIPTION_POPUP

Allows popup menu handling in the Attribute Manager. The corresponding data is DescriptionPopup.

§ MSG_DESCRIPTION_POSTSETPARAMETER

#define MSG_DESCRIPTION_POSTSETPARAMETER

Sent after a C4DAtom::SetParameter() call. The corresponding data is DescriptionPostSetValue.

§ MSG_DESCRIPTION_VALIDATE

Allows to update dependencies or to check for invalid values after a parameter has been changed. The corresponding data is DescriptionValidate.

§ MSG_DESCRIPTION_SWAP

#define MSG_DESCRIPTION_SWAP

§ MSG_DESCRIPTION_ALLOWOVERRIDE

#define MSG_DESCRIPTION_ALLOWOVERRIDE

Sent before the Take override is added to allow it or not. The corresponding data is DescriptionAllowOverride.

Since
R17.032
See also
Take System Messages.

§ MSG_DESCRIPTION_TAKECHANGED

#define MSG_DESCRIPTION_TAKECHANGED

Since
R17.032
See also

§ MSG_MOVE_FINISHED

#define MSG_MOVE_FINISHED

Sent after a handle or the object has been moved.

§ MSG_MOVE_START

Note
The material can choose to create a tag of its own, or trigger other actions, instead of letting Cinema 4D create a normal material assignment.
For example Sketch and Toon creates its own type of tag and returns it in MaterialDragAndDrop::result. Cinema 4D creates the undo for it and activates it. Inserting the tag is done by the material.

§ MSG_DRAGANDDROP

#define MSG_DRAGANDDROP

Received by an element in the Object manager when something is dropped on it. The corresponding data is DragAndDrop.

§ MSG_INITIALCHANNEL

#define MSG_INITIALCHANNEL
