Hello
I have SQL generated and placed in a JTextPane.
I'd like to color all the special word differently from the user inputed word e.g. SELECT and FROM etc.. would be BLUE and the table names would be black...
you get the idea.
Iw as wondering if anyone had done this, or had any ideas how to do it?!
Cheers
Andy
Haven't done it but maybe you could test for upper case which all the commands should be, then make the color changes.
This is something very tricky I tried to understand for a long time, but never did.
You need all that stuff from javax.swing.text for it. You replace the EditorKit by a SQLEditorKit written by you, which provides a Document implementation and a View implementation. The View can actually be an existing one (not sure), the Document should be written by you. The document tree that you generate should consist of keyword nodes and one or more other node types (e.g. value, field name etc.). Then you apply styles to the nodes to provide the highlighting.
I couldn't find any proper examples, but if you want you can dig into the NetBeans source (www.netbeans.org) and find their syntax highlighter. It should be based on the same principle.
I have found a solution, not brillaint, but effective enough for what was doing.
Its a styled documetn that basically scns through for keywords when ever you alter the text etc...
As the text (SQL) was never hopefully going to get that big, i'm happy using it this way, for the time being.
Sun offer a beter solution, but to be honesti could be bothered to write so many classes, and update the demo they had which was built for java 1.1 i think.
I've attached the .java file in case anyone want to have a look.

Dose anyone have a emplementation of this so i can see how to use it im sorta new and would like to try this out
Sure, here is a simple example,
its two classes, compile and run the Window.java class.
Its should prduce a window with a JTextPane in it, with some syntax, one this works you can work through the code int he SyntaxDocument class, there are some comments etc.... if you need any more help let me know!
Cool Thank you
