programmatically change the background color in eclipse

Question

I have a question related to eclipse plugin development. Is there any means by which I can programmatically change the background color in eclipse. I am able to change the text foreground color by calling setTextColor(color, offset, length, controlRedraw) in ITextViewer but I don't find any function by which I can change the background color of the text. If anyone has been through this kindly share your thoughts.

Thanks arav

I am not sure this can be done easily, short of extending your own version of a Text Editor, here you provide a Configuration Class which inturn accepts a PresentationReconciler Class which is like a Rule Class that tells you if you need to put a Foreground or a Background Color

See this document

PresentationReconciler

• IPresentationDamager: define dirty region given a text change
• IPresentationRepairer: recreate presentation for dirty region
• DefaultDamagerRepairer does both, based on a token scanner
• ITokenScanner: parse text into a token stream
• RuleBasedScanner uses simple rules

Extract from the presentation

Here, the null background color means, takes the default system background for that widget. (so here: white).
But you could specify whatever color you want, based on the partitioning of your document and on the rules that would apply.
