Hi,
I am actually implementing a custom LineBackgroundListener, that can
emphasize part of a text (e.g set the background color for scriplets in
jsp,or import statements in java ..).
The problem is that the CursorLinePainter, that is installed on the text
editor by the SourceViewerDecorationSupport, always crush the line
background color with the widget's background color,and therefor
annihilates the work done by any other linebackgroundListener.
The only workaround is to deactivate the cursor line painter.
I think that the CursorLinePainter should allows other contributors to
participate in the source viewer decoration.
Valère.

It is 'worst' than i thought, i have created a friendly
CursorLinePainter, but my line background contributor work is still ignored.
The problem is that the lineBackground event mechanism doesn't propagate
the line background color, i.e if there are several
LineBackgroundListeners, the styledText ask each listener if he want to
change the line background, and, if not, the line color is reset to null
(instead of keeping the previously set color).
I'll file a bug and propose to work on a fix ;).

Using a LineBackgroundListener is at your own risk and not supported by
the text framework (see ITextViewer.getTextWidget()). Simply drop that
approach and use a org.eclipse.jface.text.ITextPresentationListener.
