Re: [Pharo-users] Morphic component to display images/pictures

by Peter Uhnak

The mooc challenge (no #4) doesn't really address any of the things I am interested in (the result is the same as what inspector can currently do). Spec has ImageModel, but that doesn't even have scrollbars... anyway... I am currently refactoring Spec interpreter and after that I would like to improve some things... so maybe I could improve the ImageModel, since we don't have what I want...

Re: [Pharo-users] Voyage, DateAndTime and UTC

by Hilaire

Based on the Paul suggestion, one can write a description to get DateAndTime right. Hopefully this could be fixed in Voyage Hilarie mongoAccesstime <mongoDescription> ^ VOToOneDescription new attributeName: 'accessTime'; accessor: (MAPluggableAccessor read: [:userClient| userClient accessTime printString] write: [:userClient :string | userClient accessTime: (DateAndTime fromString: string)]); yourself Le 31/03/2017 Ã 21:06, Hilaire a Ã©crit : > Thanks for the idea. > For me it is a bug[2], like the other one related to Date persistency, > saved as DateAndTime, then shifting you one day[1]. -- Dr. Geo http://drgeo.eu
