Parameter name codemining: Selection on double-click off by one character

[derBluemel]

When I double-click on a parameter name or the parameter itself, the selection is set incorrectly.
It seems that the parameter name codemining is overlapping with the parameter itself by one character:

I also changed the background color with an org.eclipse.swt.custom.LineBackgroundListener for the attached screenshot.

@derBluemel yes indeed today we have managed like this. Inlined content annotation takes place with GlyphMetrics width. But the use of GlyphMetrics replace the character so we must redraw it.

To fix this issue, we must improve OS TextLayout. See my current experimentation with windows https://bugs.eclipse.org/bugs/show_bug.cgi?id=531769

OK! Thanks for your feedback. Doesn't seem to be an easy fix then... :(

On a side note: Why is the inlined annotation not affected by the LineBackgroundListener?

It's perhaps because LineBackgroundListener is called when a line is drawn and the draw of inlined annotation is called in the AnnotationPainter (not in the same place). Never played with it but I thing it's one reason?
