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 On Mar 21, 2013, at 11:24 AM, MartinW <wm@fastmail.fm> wrote:
I asked the same question on Stackoverflow (http://stackoverflow.com/questions/15534305/how-to-bind-a-labelmorph-textmor...) 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?
