[mapguide-users] Use Custom Function On Map

[SriRam007]

Hi,

I want to use a custom function OnMouseWheel event on the Map

ie. I want to add some code inside the original function.

I just know the code as given below But dont know how to use it so that on
every OnMouseWheel event My Function should call.

var origOnMouseWheel = null;
var mapFrame = viewerFrame.mapFrame;
origOnMouseWheel = mapFrame.OnMouseWheel;

Please anyone help me...

thanks
