morphic

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? Depends on what you want to achieve. You might want to take a look at a way to do it with Glamour in a current Moose image. In a workspace, do-it: GLMBasicExamples new

Recently a Spec documentation was released on-line , how it is related with the Polymorph project? It would be nice to read about the future of these projects. Is Polymorph discontinued? Polymorph is a UI framework. Spec is a UI description framework based on literal arrays. In other words the widgets you see on the screen come from Polymorph. A UI builder takes a Spec specification and builds those widgets: "here's a button of this size, and this is its name". In Squeak, the same relationship exists between Morphic or MVC, and ToolBuilder. 来源： https://stackoverflow.com/questions/11251663

I'd like to know about the things that make Morphic special. Morphic is much more than NSView or any other graphics class that simply allow the re-implementation of a limited set of features. Morphic is an extremely malleable UI construction kit. Some design ideas behind Morphic makes this intention clear: A comprehensive hierarchy of 2D coordinate systems is included. They are not restricted to Cartesian or linear. Useful nonlinear coordinate systems include polar, logarithmic,hyperbolic and geographic (map like) projections. Separation of the handling of coordinate systems from the morphs
