Description Tom Hofmann CLA 2006-01-16 04:00:03 EST 
3.2 M4

I am using a recent version of gnome/gtk/pango, so this may be a problem of the libraries used etc, but you may be interested anyway.

It seems that StyledText somehow computes/receives the wrong pixel offsets for text selections. A selected text range shows vertical bars at every word separator, and text colored using StyleRanges is off by one compared to the selection.

I will attach a screenshot.

Installed libraries:

pango-1.10.2
gtk2-2.8.7
gnome 2.12

Selection in StyledText (Java editor). Note the vertical bars in the background color at word breaks.

Selection of a single word. Note how one pixel is missing off the end of the selected 'StyledText' identifier.

A dup?
