Problems with a Morph that accepts File Dropping in Pharo 1.3+

by Helene Bilbo

Hi, i still have problems with a Morph that should accept files from the OS dragged and dropped onto it. I found out it works in Pharo 1.2 and in Squeak 4.3 but not in Pharo 1.3 and 1.4. Try this class: Morph subclass: #DropZone instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'DragAndDrop'! !DropZone methodsFor: 'as yet unclassified' stamp: 'HeleneBilbo 9/21/2012 20:53'! dropFiles: evt self color: Color blue.! ! !DropZone methodsFor: 'as yet unclassified' stamp: 'HeleneBilbo 9/21/2012 20:41'! initialize super initialize. color := Color red. bounds := 0 @ 0 extent: 200 @ 200! ! !DropZone methodsFor: 'as yet unclassified' stamp: 'HeleneBilbo 9/21/2012 20:53'! wantsDropFiles: anEvent ^ true! ! In Pharo 1.3 and 1.4 the DropZone Morph does only in some rare cases catch the dropped file, in most cases it's the PastUpMorph behind, that get's to handle the dropped file. In Pharo 1.2 and in Squeak (4.3) it works as it should, i.e. the DropZone always get's to handle the file dropped onto it. Perhaps someone has an idea what changed between 1.2 and 1.3 that could cause this behavior?

Spy & Pharo-1.4 MONLinearColorNormalizer>>#minimumValue: intermittent error

by Paul DeBruicker

FYI - Sometimes when running an analysis the calculation to set the color of a box in the view (Roassal/Mondrian ?) gets messed up because the result of the MONLinearColorNormalizer>>#minimumValue: send is 'Float infinity negated' I'd guess that for that method you'd never want it to be below 0 or at least bounded in some fashion.. I have not seen the error happen twice in a row.

Roassal graphically renders objects using short and expressive Smalltalk expressions. A large set of interaction are offered for a better user experience. Painting, brushing, interconnecting, zooming, drag and dropping will just make you more intimate with any arbitrary object model.
