Dear all, I have some questions about the following topics: Morphic, the Zinc-HTTP-Client-Server, and NautilusRefactoring. I am wondering if someone can help ;) I am visiting RMoD @ INRIA these days (I am now sitting at the âvisiting tablesâ @ 3rd floor of INRIA). If someone is willingness to help, please come forward! To get an idea (and hopefully to collect some answers from people outside of Lille) here are my doubts ### Morphic - How can I assess the âz indexâ of windows? For each window Iâd like to know the % that is visible on screen, i.e., not covered from other windows. - Is there a âgeneral patternâ on how to extract which entity is âdisplayedâ on a window? In System Browsers is easy, what about other types of windows? ### Zinc-HTTP-Client-Server - How can I do a real upload (HTTP post) in background? ### NautilusRefactoring - How does it work? Why there are different methods to remove a class, for example? e.g., NautilusRefactoring>>#removeClasses: vs. AbstractTool>>#removeClasses: - Why #removeClasses: is triggered before the actual removal (i.e., confirmation dialogue)? Cheers and thanks in advance, Roberto
