Morph haloClass
Last updated at 5:01 pm UTC on 16 January 2006
The class method haloClass gives back the name of the class which is responsible for putting up the halos (the dots around a Morph) when the user clicks the Blue button.

Interestingly, this method is not overridden by subclasses of Morph in Squeak version 3.4. So the only class used for bringing up the halos is HaloMorph at the moment.

You add specific halos to your morphs subclass HaloMorph and configure it by overriding methods.

The number and placement of halos is defined by the entry:
   Parameters at: #HaloSpecs
This specifications are installed when you change the halo Preferences setting.
