[Cuis] Morphic drag and drop

[H. Hirzel]

P.S. Instance variable 'worldState' of the PasteUpMorph is nil.

This is cause by the call to
   mouseButton2Activity

and that activates

invokeWorldMenu
	"Put up the world menu, triggered by the passed-in event.
	Perhaps a good place to disable it if needed"

	| menu |
	menu _ (TheWorldMenu new
		world: self
		hand: self activeHand) buildWorldMenu.
	menu addTitle: Preferences desktopMenuTitle.
	menu popUpInWorld: self


This should only be done for the World PasteUpMorph and not for a
PasteUpMorph which is a submorph of the WorldMorph


So if I subclass

PasteUpMorph subclass: PasteUpMorphHH

and do the same test as mentioned in the initial mail of this thread I
no longer do have walkbacks.


Note aside:

PasteUpMorphHH does not appear in the WorldMenu / New morph chooser.

I have to open it with PasteUpMorphHH new openInWorld
