[OpenLayers-Users] Modifiable Feature - a minimum area

[Chris Jones]

Thanks for your input Eric. Following your lead I've had a quick look at the trunk, and there is also a sketchstarted\modified\complete which might be what I'm looking for. 

Failing that, would it be possible to either use the mouse handler or renderer to achieve the behaviour I'd like?



Hi. In trunk the vector layer has the new event type "vertexmodified",
so I was going to suggest to use that when I realized that
"vertexmodified" will not be triggered when a *virtual* vertex is
moved. Maybe someone has a better idea... If not the only thing I can
think of is proposing the addition of a "virtualvertexmodified" or
something.

Cheers,

Eric
