[Pharo-project] Generalizing Keymapping idea

by Denis Kudriashov

Hello. Do you think about generalizing Keymapping idea on any event combinations (not just keyboard)? So we can write code like morph on: Mouse click ctrl do: [] morph on: $a click ctrl do: [] morph on: Mouse move shift + $b do: [] morph on: Gesture cicle shift + $x do: [] I think with such approach we can remove all morph overrides like #mouseDown:, #mouseUp. And it will big cleanup of morphic code. You know how many equal methods we have for each kind of event (handlesMouseDown:, handleMouseDown:, mouseDown: , etc). Best regards, Denis

Re: [Pharo-project] State of PharoConf videos

by Christoph Wysseier

Hi Stephan I would like to show my talk ("Selling Pharo-based Solutions" at PharoConf) to my team and enhance it for the next time. Just out of curiosity: are you still working on those videos? Otherwise, would you mind to provide the video file somehow?
