Hi,
I'm currently working on a GeoExt.ux editing tool using a bunch of
existing other ux and OpenLayers controls. Among those things, I'll
have a SelectFeature control to be able to choose which feature to edit
(obviously). But, I'd like to be able to stop the user from unselecting
a feature if it has unsaved changes and show a "save changes ?" message
of some sort. The two ways I thought of accomplishing this is to :
a) do not allow the user to unselect a feature at all ( clickout:
false and toggle: false ), which is more a workaround the issue... or
b) add a new "beforefeatureunselected" event to the
OpenLayers.Layer.Vector object, listen to it in the SelectFeature
control (in the unselect method) and register a callback method that
would return false if the feature has unsaved changes and stop the
feature from being unselected in the Control.
Does that make sense ?
Thanks,
