[OpenLayers-Users] showing tooltip over a mapserver map

[Arnd Wippermann]

Hi,

You can select and unselect a feature by hover. See example
http://openlayers.org/dev/examples/select-feature.html
 
It should be possible to show and close the popup accordingly.

Hi Christopher,

Thanks for your reply.
I have used Popup in developing another functionality wherein I fetch the
data relating to the layers that a particular lonlat belongs to like
District,Station,Roads etc.I then display it in a pop-up.

The problem with pop-up is tthat it is fixed at one place and needs to be
closed manually.
The tooltip in fact will popup and remain as long as the mouse pointer is at
that particular lonlat but should disappear automatically once the mouse is
out of that position.

It is similar to the functionality in MS Office or Open Office.
Regarding the use of other js libraries like ExtJS or tooltip libraries I
wish to inform u that I don't have any knowledge about them unlike you.
I don't have too much time to do research bec' I need to implement it within
a couple of days in my workplace.

I shall be immensely thankful if you help me with your knowledge in ExtJS or
tooltip libraries so that I am able to achieve my objective.

Thanks again for your kind reply.

Warm Regards.
