As has been done with the dragBoundry code, I suggest that we set up a "handle" boundry for a drag event. It would involve testing to see where on the layer the mouse clicks and stopping the event if it is outside the handle boundry. I'm willing to put together the code, I'm just seeing if anyone has any comments / stones : ) -- Michael Pemberton mp...@ph... ICQ: 12107010 |

you're lucky, because you don't have to do it yourself. i did this just
yesterday and it was intended to be posted this evening (CET).
i attached the modified dragevent.js-file.
there's one line added in DragEvent.lyrListener.onmousedown, the additional
code is at the end of the document.
sample code:
myLayer = new DynLayer(null,100,100,100,100,'red');
DynAPI.document.addChild(myLayer);
area = new DragArea('rect',0,100,20,0);
DragEvent.addDragArea(myLayer, area);
DragEvent.enableDragEvents(myLayer);
at the moment, two different DragArea-types are supported:
new DragArea('rect',t,r,b,l)
new DragArea('circle',centerX,centerY,radius);
multiple DragAreas can be added, to a layer
if you need more complex areas, you can add them yourself, it shouldn't be
too difficult to understand the code.

I've attached the code. I've also made a few alterations to the dragBoundry (eg. points to the parent instead of setting the value to "parent") Hope this comes in handy to someone other than me. : ) Michael Pemberton wrote: > As has been done with the dragBoundry code, I suggest that we set up a > "handle" boundry for a drag event.

I was too quick with my earlier post. the attached version works correctly and also contains an example page. Michael, I posted it at the same time as downloading your post. However, after looking at your code, it is create for use as an extension but is adds almost too much code that is not commonly used. This is very useful for something such as an image map or such. Variety is the spice of life. Michael Pemberton wrote: > As has been done with the dragBoundry code, I suggest that we set up a > "handle" boundry for a drag event.
