Subject: Re[2]: [cgmo-webcgm] Draft Proposals
Hi Ulrich, I'm rewording a few paragraphs of my initial proposal, I'll send that later. In this email, I want to focus on a question you brought up... Wednesday, November 17, 2004, 4:53:49 AM, Ulrich wrote: <snip> UL> " Instead, if the mouse pointer was over a 'grgroup' when the event UL> occurred; its closest ancestor element of type 'layer', 'grobject', UL> 'para' or 'subpara' will be designated as the target element." UL> How does layer fit in here? It is not mentioned in the paragraphs above. That's a good question (regardless of this 'grgroup' discussion)... Should the WebCGM DOM allow users to click on 'layer's? WebCGM 1.0 did not allow 'layer's to have hyperlinks and therefore could not be clicked upon. Worded differently, the question becomes; can a 'layer' be the target of a mouse event? I say NO since we don't allow event listeners to be added to layers, only at the picture level. Additionally, since 'layer's cannot have a hyperlink, there's no reason why you would want a 'layer' as an event target. Comments? Regardless of what we decide, I think I should add in a sentence or two about 'layer's in the Event interface section. Regards, -- Benoit mailto:benoit@itedo.com
