[OpenLayers-Users] How to recenter the map when drawing

[Richard Greenwood]

Steve,

This is not exactly what you are looking for, but you could watch
sketchmodified and when the mouse was within a few pixels of any edge
of the current map, you would pan the map a few pixels in that
direction. This would mimic the behavior of MapInfo's "edge panning"
(and probably other software) and it would provide the opportunity for
the user to pan beyond the current map extents to place a new vertex.
And you don't have to detect a 'click' or 'vertex added' event, which
apparently doesn't exist.

Regards,
Rich
