Hi Thomas, Great inputs. Couple of things:
1. Let me know if I can be of any help to your new-event-system- implementation. Would love to do that. 2. Regarding the specific events, I think they're available across browsers and OS. I am porting Dojo for GWT and found http://bugs.dojotoolkit.org/browser/dojo/trunk/dnd/Moveable.js#L49 So I assume, adding the events should be pretty strightforward. The only reason that I see these (and may be some more) events have been left off is probably because the current events take up the bits from 0x000001 to 0x800000. And in JavaScript, numbers are 64-bit floating points. Well, technically, if I look at -- the above should not be a constraint because looking at the specification IEEE 754-2008 (http:// en.wikipedia.org/wiki/IEEE_754-2008), it should be possible to use upto 52 digits before decimal (see also http://en.wikipedia.org/wiki/Double_precision_floating-point_format). May be, it's just a matter of time or realizing that these events also exist ;) -Gaurav www.mastergaurav.com On Oct 14, 3:02 am, Thomas Broyer <[email protected]> wrote: > On 13 oct, 19:36, masterGaurav <[email protected]> wrote: > > > Hi, > > > I am implementing Drag-n-Drop functionality in GWT, for which I need > > to handle ondragstart and onselectstart events. > > However, I could not find these two events in the > > com.google.gwt.user.client.Event class. > > > There are three parts to my posting: > > - How can I handle these events without touching the existing code? > > Events need some refactoring to be "extensible" (no longer depend on > the Event constants and sinkEvents/unsinkEvents bitfield). > It is possible to handle "new" events > > > - Is there any specific reason for not having these events? > > Time probably (to add them, with tests, etc.) and the fact that > they're not supported by all browsers. > > > - How can I submit a patch to GWT, if applicable.
