Re: [Pharo-users] have a question for morphic Designer in pharo.

by peter yoo

1. im look monticello now. can look more version now. 28, 30 2. email to Marcel Taeumel already. but not receive return mail. mabe into spam? 3. latest squeak is cannot use too. squeak 4.1 image(in squeak 4.4 all in one vm) with morphic designer standard version can use. but class not same(squeak version and pharo version). im little panic. 4. im look already. pharo canvas class not same squeak canvas class. this problem not easy. i try more now. but im newbie user. maybe so hard work. 5. im look already another UI project(http://uipainter-gsoc.over-blog.com/). but not handsome(little joke). maybe can then i want use this project. now im trace another way(for UiItemViewport class. but mouse event is not same to squeak env). thank you your answer. stephan !!!

Image starts and closes automatically

by Esteban A. Maringolo

Help please! I closed my image with "Save & Quit" and now everytime I try to open it it opens the window but closes immediately. No error or anything else. It is... the image opens, I can see a couple of workspaces. But then quits. I'm using: /pharo-ui myapp.image I also tried to start it using my startup script, and the same thing happens. Any idea? Regards. Esteban A. Maringolo

Re: [Pharo-users] have a question for morphic Designer in pharo.

by Stephan Eggermont

Thank you for the excellent problem description. Even though I don't know any Korean, the case was easy to follow. You came already quite far in making the designer work in Pharo. I tried reproducing it, but got stuck pretty fast. In a Pharo 2.0 20628 image on a mac, I opened monticello and added the repository MCHttpRepository location: 'http://www.hpi.uni-potsdam.de/hirschfeld/squeaksource/MetacelloRepository' user: '' password: '' In your description, you show that it contains a version 30. The latest version I see is 24. Is there anything you wrote in Korean that I missed to do? The Morphic Designer is maintained by Marcel Taeumel (@ hpi.uni-potsdam.de) in Squeak, and though it is no longer the focus of his research, he makes sure it runs in the latest versions of squeak. I don't think he regularly follows the pharo mailing lists. I think Marcel earlier programmed in Qt, and wanted an event mechanism as similar as possible to that used there. I already told him once that uptake might be better for an announcements based designer. It has a configuration, and the changes you have had to make should not be very difficult to put in a pharo-specific package. positionInWorld is implemented in Morph>positionInWorld ^ self pointInWorld: self position in both Pharo and Squeak. A difference is in the implementation of TransferMorph, where squeak has withPassenger:from: and pharo uses withPassenger:from:hand: Stephan

Yours is simpler, no doubt. Best regards! Esteban A. Maringolo
