Apologize all.

Too much sidras for new year :=)

Yes, always was Morph new openWorld.

And lucky us, no bugs

Cheers and is a good news see you active on list.

Re: continuous display of cursor position

Hello Bob and Edgar

For the case of tracking mouse position InfoMorph and
UpdatingStringMorph do the same.

Both are subclasses of StringMorph

UpdatingStringMorph does much more though (61 instance methods, class
comment copied in below, might need some updating).

InfoMorph is a nice example how the stepping mechanism of Morphic may be used.
It only needs two method override.

--Hannes

BTW Edgar, the code you posted was corrupted, have you seen my updated version?

CLASS COMMENT of UpdatingStringMorph

A StringMorph that constantly tries to show the current data from the
target object. When sent #step, it shows what the target objects has
(target perform: getSelector). When edited (with shift-click), it
writes back to the target.

floatPrecision = 1. to round to integer.
floatPrecision = .1 to round to 1 decimal place, etc.

Even when ((target == nil) or: [getSelector == nil]), the user would
still like to edit the string with shift-click.

Yes, but again I apologize.
As said in another mail, always use the working .morph by years.
Only take the relevant part for original question.
And as said to Bob, forget "new".
As Bob said , is Morph new openInWorld (or Morph new openInHand)
And all Morph descendant (below in hierarchy) should responds except you
override as in this case

Cheers

Scott Wallace has a "watch it" context menu item in his images that does exactly this. E.g., you simply select an expression:

ActiveHand position

and choose "watch it" from the menu, and it creates a simple updating string morph.

(similarly, there is a "button for it" menu item that executes the expression once when clicked. very convenient)
