I was successfull in making Designer start in Pharo 3.0 30659, with some help from Tobias Pape. The following changes were needed (compared to what was needed for Pharo 2.0) - floodfill2:at: is gone from Form. I replaced it with a simple fillColor: That it had gone missing was not clear from issue 11570 - outsetBy: is deprecated and replaced by expandBy: in a lot of places - (some symbol or string or something else, #:) asSymbol is replaced by ... asMutator in a lot of places. - TranslucentColor is replaced by Color TextMorph handleInteraction:forEvent: no longer exists, but gives a different problem in Pharo 2 than in 3 just replacing it by handleInteraction: does not work. That makes a mess of the selection in theUiTextLineMorphs in the object inspector. Stephan

Event handling in TextMorphs
by Stephan Eggermont Dec. 28, 2013

Dec. 28, 2013

handleInteraction:fromEvent: no longer exists in TextMorph in Pharo 3.0. Just replacing it by handleInteraction: doesn't do the right thing. What should I be doing instead? Stephan mouseDown: evt evt yellowButtonPressed ifTrue: [ ^ self yellowButtonActivity: evt shiftPressed]. self grabKeyboard. editor ifNotNil: [:e | self handleInteraction: [e mouseDown: evt] fromEvent: evt].

There is likely to be a different one for designer itself. >2. email to Marcel Taeumel already. but not receive return mail. mabe into spam? Possible, but unlikely. The last days were the worst time of the year to reach someone in Germany. The weeks around christmas (24-26 december) and newyear are family holidays, so it's likely that he doesn't read his mail. He reacted to your stackoverflow post though. >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. It should work in the latest squeak image. It is not used enough/doesn't have enough test coverage that all mistakes are immediately noticed, but Marcel fixes bugs that are found. With the quality of issue report you provide the major problem should be his availability/priorities. The next week he's likely to have holidays. >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. They started as the same, but Pharo has made more radical and drastic clean-ups. Pharo will break existing applications in order to improve things. The advantage is that innovation can be much faster in Pharo, a disadvantage is that applications need to co-evolve. The support for co-evolving is gradually improving, the continuous integration server provided for Pharo contributions gives fast feedback on consequences of changes. Squeak tries to keep compatible with older applications while gradually making everything unloadable. That is a much slower and more difficult approach. Quite a lot of code that was not used was removed. Once in a while we find out that a project uses that code and needs to be reintroduced. Or should be in a separate extension package, or be moved into the using project. The issue you are now running into seems to be the cleaning up of event handling that has taken place in Pharo and not yet or not in the same way in Squeak. A lot of the code deep in the system was very difficult to understand, so yes, this can be difficult 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). Yes, this years GSoC project did not get as far as Marcel's one. And the event handling has changed since Marcel wrote the Designer. Signals was pretty intrusive. UITreeViewPort doesn't seem to correctly set the source of its dragSpec. I tried to change dragDropSpec in UiItemViewPort to dragDropSpec ^ dragDropSpec source: self; yourself That allowed the drag-and-dropping of a lot of the widgets, but created errors where the dragDropSpec was set to nil (Tree widget). Then I looked at where UiItemViewDragDropSpec was used, and found out that the source was not set in UIDesigner initialize. I can do drag and drop of all widgets with self ui widgetList selectionMode: UiViewSingleSelection; dragDropSpec: (UiItemViewDragDropSpec new source: (self ui widgetList); dropEnabled: false; dragTransferType: #widgetClass). So, in all I needed to make the following changes to make the designer work in 20628 after loading development of ConfigurationOfDesigner-mt.24.mcz: UIDesigner>gridForm | form canvas | form := Form extent: 20@20 depth: 32. form floodFill2: (Color gray: 0.98) at: 0@0. canvas := FormCanvas on: form. form pixelValueAt: 0@0 put: (form pixelValueFor: (Color gray: 0.2)). ^ form UIDesigner>initialize super initialize. self ui setupUi: self. self ui prop addPaneSplitters. self selectDefaultModel. self ui centralScroller borderWidth: 0; fillStyle: (BitmapFillStyle fromForm: self gridForm).

Re: [Pharo-users] have a question for morphic Designer in pharo.
by Stephan Eggermont Dec. 27, 2013

Dec. 27, 2013

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

Is there any fundamental technical barrier to compiling to JVM byte codes?
by Andy Burnett Dec. 25, 2013

Dec. 25, 2013

I am sure it would be a huge amount of work, and may not be a good idea at all. However, given the number of dynamic languages that now compile to JVM byte codes, I am curious whether there is anything about Pharo that would make this impossible? Cheers Andy

WebClient Issues on Pharo 2.0
by vmusulainen Dec. 24, 2013

Dec. 24, 2013

Hi, I have loaded WebClient from ConfigurationTool on Pharo 2.0. It seems something changed at system so I had some issues while loading the package and fixed it. I would make my fixes public for community. How do it? Does exist any guide? If I right understand this document <http://www.pharo-project.org/community/how-to-contribute> describe contrubuting for Pharo and not applicable for 3dparty packages. -- View this message in context: http://forum.world.st/WebClient-Issues-on-Pharo-2-0-tp4732142.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
