Drawing revision creation handler​

This example demonstrates how the

onDrawingNewRevision
callback sends a request to the host application to store a new drawing revision, its associated drawing storage, and its updated layouts. The callback provides the host application with the new
DIQ_DrawingRevision
 record, the new
DIQ_Storage
 object containing the drawing file, the updated layouts from the previous revision, and the new layouts created for the new revision. Once the request completes, the result is returned to the widget through the

onResponse
callback.
