/**
|
|
||||||
* A simple example showing how to modify the fonts and colors used in an
|
|
||||||
* RSyntaxTextArea. There are two methods to do this - via the Java API, and via
|
|
||||||
* an XML file. The latter method is preferred since it's more modular, and
|
|
||||||
* provides a way for your users to customize RSTA in your application.<p>
|
|
||||||
*
|
|
||||||
* This example uses RSyntaxTextArea 2.0.1.<p>
