elem
- the element to create a view foraxis
- either View.X_AXIS or View.Y_AXISMethod Detail |
public void setParent(View parent)
This is implemented to forward to the superclass as well as call the setPropertiesFromAttributes method to set the paragraph properties from the css attributes. The call is made at this time to ensure the ability to resolve upward through the parents view attributes.

parent

being removed from a parent it was previously added
