> From: nicolas cellier > Have to revert to a <pragma> thing... I'm not convinced. Pragmas are at best a kludge. I liked the early gcc response to #pragma. The spec stated that a compiler could do whatever it wanted when it saw a #pragma, so gcc tried to run a variety of games and threw a segmentation fault if it failed to find any of them. - Peter

ST-80 image for Squeak-VM
by Wolfgang Helbig 24 Feb '06

24 Feb '06

Hi, I am looking for an image that is as close as possible to the one described in Adele Goldberg, "Smalltalk-80: The Interactive Programming Environment" (1983) from Adele Goldberg and which runs on a Squeak-VM from Ian Piumarta. So far I'm happily using Squeak 1.18, but it already differs in look and feel (Mac like Windows), some bugs (Form Editor not compatible with colours) and classes (no SelectionInListView and no CodeView). I'd appreciate any hint that helps to recreate this ancient beauty of ST-80. Regards, Wolfgang

Thanks to all for your quick replies. I've forwarded the digest home for me to browse at the weekend. To quote Arnie Schwarzenegger: "I'll be back!" -- Dugald

If I go to the halo menu and 'extras/put in window' it puts a system window round the PasteUpMorph.

SystemWindow
by Cowdery, Bob [UK] 24 Feb '06

If I put my morphic creation in a window is there any way to remove the window afterwards? Also I notice that setting the window colour is a bit odd. Only the border colour changes. Then by setting solid fill off the background can be set by the gradient colour and then putting solid fill back on the colour remains. Is this deliberate behaviour?

[Newbie] - Building a Morphic UI
by Dugald Wilson 24 Feb '06

24 Feb '06

Hi to all. I have played around with Squeak but not really seriously until now. Even my 7 year old has been playing with it for the last 2 years! My 12 year old has toyed with the Morphic programming bits. However, I have a VisualWorks ST app that I want to translate to Squeak, more as an exercise in learning to develop UIs in Squeak. The real code, of which there is a lot, is fairly easy to translate, and this has been done mostly. The UI remains the problem: I need radio buttons, scaled graphics, mouse interaction etc.. Several things... 1. Building a real UI seems so, so hard, especially if you want it to look "professional" rather than "string and sealing wax". Is there no UI builder? Does everyone roll their own UI? This hinders all attempts at rapid prototyping. 2. While old Squeakers might be happy about this, I do not think it useful or advisable for the app user to be able to dismantle the UI using halos, selecting UI components and spreading them around the screen. This, I find, is the most unsatisfactory part of the basic Squeak system UI: it's too easy to destroy it. 3. Although the AlignmentMorph is "on the way out", it seems quite a good idea to help in grouping items in find of frames. LayoutPolicy doesn't seem to do the same work in resizing, shrinkwrapping, spacing... 4. In the SystemWindow how do you change the colour of the title bar, short of doing a treewalk through all the submorphs to set their colour individually? An answer to these issues would, I suppose, be to subclass all the components I need for my UI to provide reasonable default behaviour. This would be building my own UI system from the very bottom upwards - a task I would rather not do. There must be a better way - surely. I have not found much documentation to help. I'm using Mark Guzdial's book as a guide but it's old - Squeak 2.7. Otherwise it's just scavenging in the Browser. Hmmph! I'm sure that the second time (if there is one) it should be quicker. -- Dugald Wilson

Hi Dugald! Have look at Tweak. http://tweak.impara.de There you have some widgets you are searching for. The technology of islands keep the widgets together. The halos of the widgets can hidden programmaticly or set by color-tool. So destroying of the UI will prevent by these things. Hope this helps.
