The simplest and preferred way to customize renderers
is through the style sheet, as explained in
Using renderers in the style sheet.
There are situations, however, where it is necessary to access and
modify renderers dynamically while the application is running. For
example, you may want to disable the
LinkLayout renderer
temporarily and re-enable it later without reloading a new style sheet,
which would re-create all the graphic objects. This section explains
how to do this in your
Java™
code.
