OnOpenTab

The On event can be implemented by a script add-in to receive notification when a new tab opens.

Method Name:	OnOpenTab
Argument Type:	OpenTabData
Return Type:	none
Description:	The OpenTabData.tab property identifies the newly opened tab. Note that this method is not called when a new Lister is opened, irrespective of how many tabs it contains - instead, you can identify all the tabs in the newly opened Lister by implementing the OnOpenLister event.
