Hi,<br />
<br />
I want to customize JTextField so that it will display positive numbers in blue and negative numbers in red. &nbsp;I can't simply rely on the focus events because I sometimes change the value inside the PlainDocument directly. &nbsp;I was thinking about extending JTextField and customizing its behavior upon a document change event. &nbsp;However, I am not sure about the details, and the code is complex to trace through.<br />
<br />
Any ideas? &nbsp;Thanks.

Make JTextField display positive# in blue and negative# in red?

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
