Re: [Pharo-users] Getting the last keyboard key pressed when using a RubScrolledTextMorph

Sadly not, because with that experiment there is a DNU when opening the editor which is quite strange. I can show you tomorrow if you like ;-) On Apr 6, 2015, at 15:31, Alexandre Bergel <alexandre.bergel(a)me.com> wrote: > > I would expect proper announcement to be created.

I would expect proper announcement to be created. The small experiment we did in your office suggests this.

Getting the last keyboard key pressed when using a RubScrolledTextMorph

by Johan Fabry

Hi all, the code below gives me the number representing the last keystroke. It is a bit of a hack, so I was wondering if there is a cleaner way to do this when using a RubScrolledTextMorph (I tried subscribing to different announcements to no avail).

Glamour has a morph presentation that can embed any morph.

Canadian Smalltalk Competition

by Ben Coman

Richard Eng visited the Pharo community a while ago being very enthusiastic about his Smalltalk Renaissance project. His strategy didn't end up fitting the community, but I find his kickstarter to run a Smalltalk coding competition for secondary students interesting. Apart from straight altruism to support it, providing a wide exposure of students to the concept of Smalltalk just before they enter university should generate some spillover to our communities. A rising tide lifts all ships. And community networking is a funny thing, some of those students will have parents in strategic positions who would never otherwise be exposed to Smalltalk. Its worth considering.... https://www.kickstarter.com/projects/1520902870/canadian-smalltalk-competit… cheers -ben

Display morph in GT inspector

I tried to figure out how I can display a morph inside a GT inspector presentation. How can I add a non-string representation to a composite given in an gtAnyIn: method? thanks, Norbert

If you have the amount auf characters you want to omit you can do 'BormParticipant' allButFirst: 4 Norbert > Am 06.04.2015 um 12:34 schrieb Peter UhnÃ¡k <i.uhnak(a)gmail.com>: > > Hi, > > am I really blind, or is there no way to do something like > 'BormParticipant' removePrefix: 'Borm' "-> 'Participant'" > or > 'BormParticipant' copyFrom: 5 "-> 'Participant'" "OrderedCollection knows this" > > I can do copyFrom:to:, but that requires asking the size of the string, which is (in my eyes) ugly. > > So is there better (=single message) way? > > Thanks, > Peter
