I would "just" add the support for exclusion object inside textblock. Something that would work like the clip API, but the other way arround and just for textblock. It is doable, not easy, but basically only one C file should be modified, src/lib/canvas/evas_object_textblock.c around function _layout at line 2047. This feature is somewhere inside Evas TODO list, but not an high priority right now for anyone as far as I know. So if you are skilled in C, have some aspirin, this could be a good standalone patch for evas waiting for anyone to spend time on it... -- Cedric BAIL ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
