Ready to play guinea pig for UI improvements
by stepharo Jan. 22, 2016

Jan. 22, 2016

Hi guys Many of you may bthink that I'm mad or whatever about new UI elements. Sometimes this is true :) but most of the time not. I'm just going straight and (harsh) comments. So what I propose to the GT team is the following: I'm ready to be a guinea pig Each time they want I will record a screenflow of my interaction or perception about new/different tools. I will follow a UI debugging process an expert proposed: talking aloud about my hypotheses while interacting and discovering the tools. I play that in the past with other people and it works well. I encourage other people to do the same to give feeback to GT team. Stef

[ann] spotter processors as settings
by Tudor Girba Jan. 22, 2016

Jan. 22, 2016

Hi, We now have a new little feature in Spotter. Take a look: Basically, you will get a setting for each processor defined in the image. This happens dynamically. If you disable the setting, the processor will not be available anymore. Please give this a try and let us know what you think. We would also like a code review related to the way we deal with dynamic settings. Right now, the magic is done in GTSpotterExtensionSettings (this is real magic - read the class comment), but the current solution relies on a doesNotUnderstand: to maintain the list of disabled processors. I would more prefer it if we could create a DynamicSettingDeclaration that would be able to pass arguments to one central selector. Cheers, Doru -- www.tudorgirba.com www.feenk.com "Quality cannot be an afterthought."

This is a much more complex and challenging subject that you might think. There has been a lot of work done on this for many years, many approaches have been tried. I am pretty sure that the people behind the Pharo Bootstrap project are aware of the existing literature. > On 21 Jan 2016, at 09:49, Peter H.

Rationale for RGClassDefinition>>definition?
by Stephan Eggermont Jan. 21, 2016

Jan. 21, 2016

is defined as ^ self realClass definition instead of ^self definitionSource and not two levels up at RGBehaviorDescription to make it work for MetaClass and Traits. Why is that? Stephan

It first told me close other tabs for it to load a database which was weird I double clicked and then the interface turned 3D sidewise and i could not bring straight , also it shadow created a mouse pointer that was offset to my touch event. Touching was bringing a world menu and there was also a workspace mixed with the images On Thu, 21 Jan 2016 at 20:45, Craig Latta <craig(a)netjam.org> wrote: > > > Does not render well on my iPad and has problems with multi touch. > > Hm, it should be ignoring multi-touch gestures.
