Re: (aside) MIME type
On Sun, Feb 19, 2012 at 4:55 AM, Julian Reschke julian.resc...@gmx.dewrote: The correct term IMHO is (Internet) Media Type, so disambiguation is possible. I don't believe it's helpful to maintain different sets of terminology. Use the official term, and when disambiguation is needed, it's trivial to do so. MIME type is what people in the real world call it. I don't believe it's useful to try to push terminology which is different from what things are actually known by, least of all when it leads to ambiguity. -- Glenn Maynard

I think Hallvord is trying to keep away from the hot debates and referencing one stable and one moving target, and he tries to be somewhat compatible with both at least at time of issuing. paul

The term default action is simply a sort of language shortcut to say what happens when the event is not cancelled. It's well established (just like I'd argue MIME type is) and I see no real problems caused by its usage. /Hallvord
Re: [Clipboard] checking if implementation allows reading/writing a given type to the OS clipboard
Siterer Paul Libbrecht p...@hoplahup.net: Hm.. you mean a page should be able to say Hello web browser, I just lve processing application/pdf data from the clipboard ? I don't see the use case for that. If I'm misunderstanding you please clarify :-) It means that if pdf is in the clipboard the paste command can stop being greyed out! Aha. I keep forgetting the UI part of this, thanks for the reminder and clarification ;-) I think that the best way to address this is to spec the before(cut|copy|paste) events, let them be real ClipboardEvents (no idea what interface they use in IE and Chrome at the moment but I think they are so rarely used we can rework them a little) and say that clipboardData.types should be populated according to real supported types on clipboard in the beforepaste event. Hence, a page that can handle PDF data being pasted can listen for beforepaste and check if event.clipboardData.types contains application/pdf. (Just my preliminary thoughts, nothing about before* events is spec'ed yet and actually I don't think they are an elegant solution. Perhaps a clipboardchange event would be more elegant? Clipboard change listener could do: if(event.clipboardData.types.indexOf('application/pdf')))event.clipboarData.enableUI('paste'); Or something like that? We could also define DataTransfer.enableUI('copy')) to be called at any time without any event listener workarounds..) Similarly, shouldn't something such as if(event.clipboardData.isTypeSupported('foo/bar')) ... be callable before the event is triggered? That was my intention originally, but I'm also worried about fingerprinting potential when letting scripts access new data about an end user's config. Hence, I'm now intending to limit it to being called inside event listeners like the other DataTransfer methods. I also think that if the event is synthetic the method should not reveal actual config details. /Hallvord

Cancelling the default action has different outcomes for the different types of events. Some of the outcomes are also easier to understand if you think that the default action *is* no-op (rather than thinking skip handling the default action). You can use the wording I gave above (modified here slightly): 7. Fire an event using the *ClipboardEvent* interface, with its *type* attribute initialized to *e* and its *clipboardData* attribute initialized to *data transfer*, at *event target*. If the event's *canceled flag* is set then abort these steps. 8. If *e* is: *paste*: The bits about the focused node and the context is editable above should probably reference something specific in HTML. Quite possibly, but I'm not sure where to find it.. (I don't either. I'll leave these to people more familiar with those topics...)

In new versions of Chrome, any kind of MIME type is supported in the sense that you can set data for any arbitrary type, and it can be understood by any browser that uses the same native conventions (I'd be happy to work with any other developers interested in making sure this works across different browsers on the same computer). That's interesting. How do you do that, on Windows in particular? Have you registered a clipboard format called MIME type of main clipboard part where you store type strings, or something? -- Hallvord R. M. Steen, Core Tester, Opera Software http://www.opera.com http://my.opera.com/hallvors/ Chrome registers a clipboard format on Windows called Chromium Web Custom MIME Data Format (we do the same thing on Mac and Linux at the moment to keep the various implementations similar), and when we see an attempt to add data of a type which we don't have a native translation for, we just place the string in there. We currently have a bug open to figure out how to standardize the serialization, so we can stop using the Chromium-specific types. I'd like to extend it to binary data at some point too. With respect to enabling copy/cut/paste in context menu items, IE/WebKit have beforecut/beforepaste (both) and beforecopy (WebKit only?) events that fire before a context menu is displayed. I'm not sure how widely used they are though. That being said, it'd be nice to have something that works well for native context menus and custom editing controls created with HTML elements like the one at http://ckeditor.com/demo. Daniel
