@discussion The expression view is the view that displays the contents of the
|
|
expression storage. Normally you should not call the setter of
|
|
this property. It is automatically assigned when the <code>@link
|
|
//apple_ref/occ/instp/MPExpressionView/expressionStorage@/link</code>
|
|
property of the <code>@link
|
|
//apple_ref/occ/cl/MPExpressionView@/link</code> class is set.
|
|
|
|
When this property is set the receiver assumes that the
|
|
displaying expression view has changed. It then adapts to the
|
|
properties of the new expression view and discards the root
|
|
layout.
