[OpenLayers-Users] Labels/Tooltips on mouse over a Vector layer

[Adrian Popa]

Hello Pavel,

Great idea... However - I would like to keep popups for when I click on 
an item.
Would it be possible to do something like:

layer.events.on({ "featureselected": onLocationSelect, 
"featureunselected": onLocationUnselect,  //open regular popups
                                  "onMouseOver": onLocationMouseOver, 
"onMouseOut": onLocationMouseOut
 });?

Problem is - I don't see those kinds of events on my layer. These are 
the event types for a vector layer:
0 "beforefeatureadded"
1 "beforefeaturesadded"
2 "featureadded"
3 "featuresadded"
4 "beforefeatureremoved"
5 "featureremoved"
6 "featuresremoved"
7 "beforefeatureselected"
8 "featureselected"
9 "featureunselected"
10 "beforefeaturemodified"
11 "featuremodified"
12 "afterfeaturemodified"
13 "vertexmodified"
14 "sketchstarted"
15 "sketchmodified"
16 "sketchcomplete"
17 "refresh"
18 "loadstart"
19 "loadend"
20 "loadcancel"
21 "visibilitychanged"
22 "move"
23 "moveend"

Any idea what the events would be? If they are supported?
