The Rationale behind Spec - questions
by Kenneth Payne April 17, 2013

April 17, 2013

As a newcomer to smalltalk and Pharo I must say I love it - but I'm a little mystified by Spec. Just as I've got my head around Polymorph and can build an interface with UITheme builder, the paradigm has changed and Spec is the new standard way to create a UI. I read on a post that Polymorph is a UI framework but Spec is a UI description framework. But Spec isn't just a description like a XML representation of a UI - it brings new UI objects to the party - ButtonModel, LabelModel etc. But none of these have the rich properties of the corresponding Morphic objects. A ButtonModel looks nothing like a button, for example, and the LabelModel has nothing to set a font for the label. And it's not a description it's just more code. The only way I can see to create a rich interface using Spec is to create the interface using Morphs (and composite Morphs) and then using Spec mainly just to assemble and position them. So can someone wiser than I answer these questions for me: One, what is the purpose of Spec - what problem is it trying to solve? Two, what advantages are there to building a UI in Spec rather than building it directly in Polymorph? Three, why are the objects caled ButtonModel, LableModel etc when they are not models but UI components? Four, am I supposed to be assembling morphs using Spec? It works so is it right? To sum up, I'm quite sure Spec is an important new feature but at the moment I'm just not getting it. Can anyone help me on this?

Hi, We have two players in town. I want to use a tree morph. On some nodes I want different font, on other ones I want custom morph. Which one should I investigate on? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Programming desktop applications in Morphic
by Zeeshan Ansari April 16, 2013

April 16, 2013

Hi All, I'm writing a desktop application and wanted to know what is the best way to do this in Morphic. For example, in .Net I would have event-handlers for specific events from the different window components (dialog, menu, etc) for which I would code the behavior I wanted. Does Morphic follow a similar paradigm? Are there any examples to look at? Thanks.

You might want to take a look at Roassal combined with Glamour. That might save you a lot of work. The easiest way is to download a Moose 4.8 (that is based on Pharo 2.0) Stephan

Regex with Quantifiers
by jtuchel April 15, 2013

April 15, 2013

It seems Pharo's Regex package does support quantifiers, but not correctly. Or I am completely on the wrong track here. If I inspect this in a workspace: '123' matchesRegex: '\d{1,3}' I would expect the result either to be true or an exception. True if quantifiers were supported, an exception otherwise. The Regex-Tests do not test {}, so I am not sure if the matcher is supposed to support it. Can anybody shed some light on this?

Is it correct to speculate that Pharo spec is based on VisualWorks spec? If so, can someone please elaborate? Thanks, -Paul
