Yet another "building a GUI" question

by Sergi Reyner

Hi everyone! This is my first message to the list. I've been learning Smalltalk and toying with Pharo 2.0 for some weeks now. One thing that has me puzzled is the many different ways to build GUIs. IÂ´m rewriting an app in Pharo as an exercise. It needs to display images in some parts. So far, I have: - Sent messages to (UITheme builder) - Created a SystemWindow, then #addMorph: to it, sending them #model: and so afterwards. - Tried and somewhat succeeded in building my GUI with Spec, which apparently doesn't know about images. - Read some stuff about Athens - Read some stuff about Morphic 3, and wondered if it will make its way into Pharo. - Read something about how Spec has changed a lot in Pharo 3.0 (which is labelled as alpha) On top of that, as I understand it, building GUIs with Morphic was originally meant to be a visual live process, however what I've read so far takes a programmatic approach. So... many questions, few clues, I am lost. I definitely need to use some AlphaImageMorphs in certain parts of the application, and while I find Spec's way easier, I'm at a loss when it comes to that part. On the other hand, it's sold as "the new way to build GUIs" so I'm not sure if these are missing things that will be included later, or if I'm supposed to implement them on top of the Spec framework, or even if thereÂ´s already a way to do it and I just don't get it :S Cheers, Sergi

Roassal design question

by Peter H. Meadows

When using ROLightlyHighlightable the color is changed by giving the element to ROBlink which then sends #color: to the element's shape. What is gained by doing it like this? Wouldn't it be simpler for the element itself to be able to set the color of it's shape? (Also couldn't each shape be a subclass of element?)

Re: [Pharo-users] CogVM arguments in Win32

Well, this should rather be: handle :=NativeBoostWin32 squeakWindowHandle. window := NBWin32Window new value: handle; yourself. window hide. or window setWindowText: 'im a main window blablabla'.
