radioCollection( [string] , [collectionItemArray=boolean], [defineTemplate=string], [exists=boolean], [gl=boolean], [numberOfCollectionItems=boolean], [parent=string], [select=string], [useTemplate=string])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

radioCollection is undoable, queryable, and editable.

This command creates a radio button collection. Collections are parented to the current default layout if no parent is specified with the -p/parent flag. As children of the layout they will be deleted when the layout is deleted. Collections may also span more than one window if the -gl/global flag is used. In this case the collection has no parent and must be explicitly deleted with the deleteUI command when it is no longer wanted.

Return value

stringFull path name to the collection.

In query mode, return type is based on queried flag.
