The EGL editor provides a source assistant that helps you edit dataItem parts. The source assistant displays all of the valid properties for a dataItem and lets you enter values for those properties. The source assistant validates the values you enter. When you are finished, the source assistant writes the EGL code to define the dataItem part.
