stretch type will stretch the appropriate element to match the height of the tallest
object in the element's group. All elements between
<elementGroup>
and
</
elementGroup>
are in the same group. The
<elementGroup>
element can have other
nested
<elementGroup>
elements. If no
<elementGroup>
element is defined inside a
<band>
, then all elements inside the band are considered to be in the same group.
Using the <frame> Element
JasperReports 1.1 introduced a new report element, the
<frame>
element. The
<frame>
element allows us to group elements together and give them a common
look. For example, we can set the background color of the frame and it will be
inherited across all elements contained within the frame. Frames also provide a
straightforward way of placing a border around multiple report elements. The
following JRXML template is a new version of the example in the previous section. It
has been modified to illustrate the use of frames.
