Trying to see why LocaleTest testLocaleChanged fail , I got the attached But I have: NaturalLanguageTranslator>>#isDomainLoaded: isDomainLoaded: aDomainName "ask if translation dictionary for the domain has been loaded and available now for use" self subclassResponsibility. GetTextTranslator>>#isDomainLoaded: isDomainLoaded: aDomainName | mo | mo := moFiles at: aDomainName ifAbsent: [nil]. ^mo isNil not. InternalTranslator>>#isDomainLoaded: isDomainLoaded: aDomainName ^true Some could teach me what is wrong? I do not touch any of this methods. Edgar

touch-screen interfaces
by Chris Muller 30 Mar '12

30 Mar '12

> And the current Squeak interface is made for a mouse. There would have to be a serious UI redesign to make a nice touch-based Smalltalk development environment. I think there is a place for touch-screen interfaces: Like in-car navigation systems or airport kiosks, or libraries, etc. However, I think they really are a downgrade in user-interface power. Most obviously, the power of pointing is gone. *Pointing* at something provides a non-mutative way to interact with another entity (person or computer). You can't do that with an iPad -- you can only "click" (e.g., agitate the interface). I think this is one reason I find Android / iPad so inherently non-intuitive to learn and use. I can't "hover" over the icons for a description of what they do -- I can only click on them and, if it isn't what I wanted, frantically look for the "back" button before I get signed up for something I didn't want. Which leads me straight to the other big problem I've noticed with TS interfaces: Modality. Regardless whether there are multiple programs running, all I ever SEE are people looking/working on one thing at a time. Shit we've gone back to the days of 8-bit computers with all of this modality. Also, with touch-screen interfaces, the back of my hand is constantly occluding the UI itself and the screen gets finger prints. This reduces immersive effectiveness by reminding you that you're just looking and interacting with a *screen*, not the world of objects rendered on that screen.. Apple made touch-screen interfaces "take over the world" even though they're bad on several levels. But, like I said, I think they're appropriate for in-car nav or limited-path apps. Not creative development though.. - Chris
