Object 50 "Callback" (Entities) Changed in Version 2021.0

Data Block Sequence

Any list of data blocks

A container is a callback object used to display dynamic feedback data in the display data of extended objects. It is basically used by plug-ins to store additional data in extended objects that influences the drawing screen display, but not the output. When found directly within a drawing, it will be discarded.

When found inside the display data of an extended object during screen display, the plug-in will be called with additional display parameters in order to draw any feedback information necessary. See MKI_PlugInNotify for details.

It may contain any type and number of data blocks, the serving application will ignore the object and all its contents.
