The overflow element
An element that controls what happens when the parent subform or subform set overflows the current
layout container.
<overflow
Properties:
id="xml-id"
leader="cdata"
target="cdata"
trailer="cdata"
use="cdata"
usehref="cdata"
>
</overflow>
The overflow element is used within the following other elements:
proto subform subformSet
The id property
A unique identifier that may be used to identify this element as a target.
The leader property
The value of this property is either a SOM expression (which can not start with '#') or a '#' followed by an
XML ID. The SOM expression or XML ID points to a subform or subform set to be laid down at the top of the
next layout container. When this property is empty or blank no special action is taken on overflow.
Note that this replaces the
overflowLeader
attribute on the deprecated
break
element.
The target property
The value of this property is either a SOM expression (which can not start with '#') or a '#' followed by an
XML ID. The SOM expression or XML ID points to a
contentArea
or
pageArea
which becomes the next
layout container. When this property is empty or blank the next layout container is determined by the
properties of the current (overflowing) layout container.
Note that this replaces the
overflowTarget
attribute on the deprecated
break
element.
The trailer property
The value of this property is either a SOM expression (which can not start with '#') or a '#' followed by an
XML ID. The SOM expression or XML ID points to a subform or subform set to be laid down at the bottom
of the current (overflowing) layout container. When this property is empty or blank no special action is
taken on overflow.
Note that this replaces the
overflowTrailer
attribute on the deprecated
break
element.
The use property
Invokes another object in the same document as a prototype for this object. The content of this property is
either a SOM expression (which cannot start with '#') or a '#' character followed by an XML ID.
