How can my Morph reflect changes in the object it displays?
by MartinW March 21, 2013

March 21, 2013

I asked the same question on Stackoverflow (http://stackoverflow.com/questions/15534305/how-to-bind-a-labelmorph-textmo…) 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 Walk asked: >How to bind a LabelMorph/TextMorph to a variable so that the Morph reflects >changes of the variable? That is a very low-level question. Do you just want to know, or do you want to use it? When building UI's in Pharo, the first question should probably be: can I get away with building it in Glamour. That is a high-level UI toolkit specialized in creating browsers. If you can, it is much less work. Stephan Eggermont

new (learning) project - tiangle with draggable points on a screen
by sminni March 21, 2013

March 21, 2013

Hi I have a small project (a real requirement) and I want a little guidance to do it (myself) - pl. assume I am new to pharo though I can navigate the IDE & have a background in O-O development. 1. Draw a triangle with draggable handles on points 2. The sides length and angles will be displayed (in editable fields) 3. We can lock any of the sides / angles 4. If the side / angle is edited then an action can be initiated to recomplete the triangle by redrawing the side clicked next Thanks Sanjay ----- --- Regards, Sanjay -- View this message in context: http://forum.world.st/new-learning-project-tiangle-with-draggable-points-on… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Why are SmallTalk projects/source code hosted on SS3 Gemstone instead of Git?

Victor Stan wrote: > Why are SmallTalk projects/source code hosted on SS3 Gemstone instead of > Git/GitHub? Because we have been using DVCS since a few years before git.

Because it isn't that good. It is better than what we now have widely deployed, but it doesn't come close to what we can do when we find the time to integrate all the nice research tools. GitHub is centralized and a single point of failure. We will see it replaced by a distributed system. So it is a question of how much effort we want to put into what for us can only be an intermediate tool chain and way to connect to non-smalltalk parts of the systems we develop. Stephan Eggermont

suggestion for book code snippets
by Paul Davidowitz March 20, 2013

March 20, 2013

I think it would be a good idea to have the book code snippets Incorporated into a SUnit regression test suite. (If doc is not treated as code, then sooner or later it will get out of sync...)

Glorp + Postgres array type
by Chris March 20, 2013

March 20, 2013

Hi, does anyone know if Glorp supports the array type in Postgres? I did a basicExecuteSQLString: and it came back with '{1,2,3}' so as if it might not be too complicated to make work for my scenario at least. I really want to do a toManyMapping using these integers in the array as a join to another table and have it resolve their objects, but wouldn't know where to start! Thanks Chris
