Interesting. I still cannot see anything newer than .24 in http://www.hpi.uni-potsdam.de/hirschfeld/squeaksource/MetacelloRepository Are you sure that it is exactly the same repository? 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).
