dropzone on a web page
It's good to see the World Out There starting to adopt drag-and-drop in some situations where Acornuts have taken it for granted for 30 years. For instance http://onlinemd5.com is a service that calculates the MD5 checksum for any file without having to upload it: you just drag the file out of its directory to the dropzone on the web page. This works a treat in Windows on my laptop. Unfortunately, though, not in RiscOS Netsurf: if the file is a Jpeg or text, Netsurf displays the picture or text rather than feeding the file to the MD5 calculator. Of course, it could be that the calculation is performed by Javascript so Netsurf couldn't handle the job anyway. But I'm curious about the technique involved in registering a file's pathname by this "dropzone" method. Can Netsurf cope with this in principle? -- Jim Nagelwww.archivemag.co.uk

This "dropzone" tenchniqe relies upon adding a div element with a "special" class around a form with an input of the file type (which we support and actually you can drag and drop to such widgets already). The surronding div elemnt has a javascript "drop" event added to it which gets the filename dropped and updates the form file widget. At this time the NetSurf javascript implementation supports very few events, this support does not include any of the "drag and drop" events. > > Of course, it could be that the calculation is performed by Javascript > so Netsurf couldn't handle the job anyway. > > But I'm curious about the technique involved in registering a file's > pathname by this "dropzone" method.
