how to use org.apache.fop.layout.AreaTree

[Baptiste Burgaud]

Hi all,   I'm not sure whether this is the right list or not (I already posted this mail to the fop-user list, but no one did answer). Please excuse me if you find this mail inappropriate. I need to get the accurate rendered height (in pt) of a fo:table object (to place fo:blocs below using fo:block-container with absolute position). I think I can get this size adding the getContentHeight() result of the appropriate areas in the org.apache.fop.layout.AreaTree object (initially _areaTree in Driver class). Unfortunately, I don't have much time to look around in FOP source, does someone know how where and when (!...) I should get this object? Is it possible within the FOP API (I certainly won't risk a rebuild...)?   thxs in advance, Baptiste
