Hi fellow hackers, While investigating this bug
https://bugs.freedesktop.org/show_bug.cgi?id=33100 which involves Windows' clipboard handling, I've come to the realization that, there are two ways to communicate with the clipboard on Windows. One is to use the regular clipboard API http://msdn.microsoft.com/en-us/library/windows/desktop/ms648709% 28v=vs.85%29.aspx which allows you to open, close, query the available formats, and fetch the raw clipboard data stream for a requested format. The other way is to obtain the IDataObject instance from the clipboard, and fetch the clipboard data stream from that object. http://msdn.microsoft.com/en-us/library/windows/desktop/ms688421% 28v=vs.85%29.aspx First of all, I don't quite understand why two different ways, and what the differences are between the two. Our current clipboard implementation in dtrans uses the IDataObject-based approach. Now, as I discovered while investigating the bug, using the IDataObject method does not necessarily return all available clipboard formats, whereas using the regular clipboard API does. I was thinking naively about perhaps replacing our current IDataObject-based approach with the clipboard API based one, but the whole data transfer code does more than just handling the clipboard, so I don't really know how feasible replacing it would be... Does anyone have a better grasp on why we do it the way we do? Feedback and suggestions very much appreciated. Also, if anyone wants to grab Bug 33100, s/he will be more than welcome. :-) Thanks, Kohei -- Kohei Yoshida, LibreOffice hacker, Calc _______________________________________________ LibreOffice mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/libreoffice
