Building UI with Spec vs Pharo
by Peter UhnÃ¡k July 9, 2014

July 9, 2014

Hi, what is the recommended framework for building UIs? As I understand it Spec should be able to handle pretty much anything, however Glamour has quite a lot of nice features and was recommended here http://forum.world.st/Roassal-amp-Spec-td4690745.html as a higher-level abstraction framework (albeit the issue here was mostly Roassal which as I understand is a non issue since there is Roassal2Spec package). However I haven't seen things like forms (text inputs, checkboxes, (radio)selects, buttons) or popups (yes/no confirmations, prompts) made in Glamour so I am unsure whether it is possible. Thanks, Peter

Not much has changed since then. If you can manage to get away with using a higher level framework, you save time and effort. Glamour has less choice in widgets and layout, but in both you'll probably end up adding something that isn't there/ready yet. To understand how to add/complete something you'll have to dive into (Poly)Morph(ic) for both Spec and Glamour. Stephan

Red Exclamation in Nautilus?
by Tim Mackinnon July 9, 2014

July 9, 2014

Guys - it's been a while since I've used Pharo, and in 3.0 its come along with leaps and bounds. But I'm struggling to know what many things mean, and what the UI is telling me? Is it written up somewhere? I also quite quickly seemed to get into troubles with the new Nautilus browser where it gives me walkbacks and won't let me select things. I've started again with a new image and am trying again to do some simple things - and see if I can come up with the use cases. As a starting point - I've just created a new class, with a new Category name and the class has a red exclamation mark next to it. What does that mean? Also what is the difference between Add Class, and Add full Class in the context menu? I ended up just typing over the definition of an existing class as there is no flyover help for either of these to know what it does?

Mongotalk & db.collection.distinct()
by phil＠highoctane.be July 8, 2014

July 8, 2014

I am now using MongoTalk for a project and I wanted to use distinct. But there seems to be no support in the version that I do have. So, I had a look under the hood on how the driver worked. I came up with this: mongo := Mongo default open. db := mongo databaseNamed: 'somedb'. aCommandDict := { 'distinct' -> 'somecollection'. 'key' -> 'XYZ'. 'query' -> nil } asDictionary. reply := db command: aCommandDict. (CollectionValidation on: reply) isOK. distinct := reply at: #values. It would be nice to have some support for the distinct command in MongoTalk. Especially in order to populate dropboxes etc with choices. I have been looking at Voyage too but the data is not produced by my application, so there is little use for me to have #instanceOf fields etc. I will also need aggregation commands on my data set. Are these things somewhere to be found or do I have to look into how the shell does things and move from there? TIA Phil

drawing morphs with athens

Feel free to ask questions, in this mailing or in some other about Roassal. We will try to provide all the support you need.

drawing morphs with athens
by Peter UhnÃ¡k July 7, 2014

July 7, 2014

Hello, I'm currently working on drawing engine (Ã la Squeak Connectors) as a part of school project and have a couple of questions about Morphs and Athens and would be grateful if someone could enlighten me. What is the difference between "Morph>>#drawOn:" and "Morph>>#drawOnAthensCanvas:" if I draw on AthensCairoSurface? Should I always use the latter or will there be switch to the former once everything is rendered using Athens? Should AthensMorphWrap be around every morphic element or just the top level? i.e. CanvasMorph (owner of the surface) will have a single submorph AthensMorphWrap which will then hold all the morphs (EllipsisMorph, RectangleMorph, ...) which are being drawn on the canvas. Thanks, Peter
