Ben,

But then how does this work ?

| point |
point := 1@2.
point inspect.
[ 5 seconds asDelay wait.
 point setX: 10 setY: 20 ] fork.

You can see the inspector change its printString, without ValueHolders>>contents: being involved, just a direct instance variable assignment.

For this kind of situation, my solution is to use a valueHolder

instead of storing your string directly in an inst var, store it into the value holder

initialize
string := '' asValueHolder

string: aString
string contents: aString

string
^ string contents

And then what you can do in your initialise is

string whenChangedDo: [:newValue | self label contents: newValue ]

Something like this should work ^^


The other solution (which is baaad, but can still be seen) is to have a step method refreshing the Morph.
But this is really not efficient

Hope it helps,
Ben

I asked the same question on Stackoverflow
(http://stackoverflow.com/questions/15534305/how-to-bind-a-labelmorph-textmorph-to-a-variable-so-that-the-morph-reflects-chan)
but as i do not know how much the audiences overlap i hope you do not mind
if i repeat it here:

How to bind a LabelMorph/TextMorph to a variable so that the Morph reflects
changes of the variable?

- I have an object with a variable containing a String.
- I have a window containing a LabelMorph/TextMorph (or some other Morph
that displays Text?).
How do i bind the LabelMorph/TextMorph to the variable, so that the label
updates when the String in the variable changes?

- classic Smalltalk-80 dependent/change/update mechanism?
- Pharo Announcement framework?
- something different??
How would i do this? Which Morph should i use?

Martin.
