[OpenLayers-Users] annotations undo-redo

[Dimitrios Sferopoulos]

Hi all,

I'm trying to implement an undo-redo functionality for openlayers 
annotations. Unfortunately openlayers is a bit inconsistent with raising 
events, for example moving a feature does not raise any event 
whatsoever. Also changing the style of a feature is not firing any event 
neither.

I don't want to go through the pain of adding listeners to every 
individual button on my annotations toolbar that does not fire an 
openlayers event as that would be rather messy.

What would be the way to go with this? Is it possible to extend 
openlayers to for example raise an event when a feature is moved?


Cheers
Dimitrios
