I was fortunate to meet Ward in 1994 and to have one of his colleagues as my mentor. In his paper, "The CHECKS Pattern Language of Information Integrity" Ward advocates a non-intrusive, non-modal UI style. I highly recommend reading it if you're interested in making user-interfaces that interact appropriately with people. Above, Tim is proposing we "Echo Back" confirmation of user-input: http://c2.com/ppr/checks.html#4 I'd bet it wouldn't be difficult to do -- we know we can draw a 1-pixel border around any rectangle, and whatever action is performed on mouseClick (or on mouseDown vs. mouseUp) said border could be drawn, then the action, THEN the highlight. Sounds good! </pre> Chris Muller 2013-05-22T15:49:51 http://permalink.gmane.org/gmane.comp.lang.smalltalk.squeak.general/169168 <pre>A new version of Morphic was added to project The Inbox: http://source.squeak.org/inbox/Morphic-kb.652.mcz ==================== Summary ==================== Name: Morphic-kb.652 Author: kb Time: 22 May 2013, 4:50:12.27 pm UUID: 73334963-ccc3-4f41-8fec-fc64d40db333 Ancestors: Morphic-fbs.651 Implementation of pre selection highlight in PluggableListMorph.

Dave </pre> David T. Lewis 2013-05-22T11:57:45 http://permalink.gmane.org/gmane.comp.lang.smalltalk.squeak.general/169163 <pre>Part of the System -&gt; MorphicExtras dependency stems from references to CommandHistory. Now it seems that CommandHistory has almost nothing to do with MorphicExtras. The only thing that ties it to that package is CommandHistory class &gt;&gt; #resetAllHistory, which has the line MorphExtension withAllSubclassesDo: [:mexc | self forgetAllGrabCommandsFrom: mexc someInstance] So it occurs to me that CommandHistory is useful beyond the context of a MorphicUI, and hence perhaps we can resolve this territory dispute thusly: * move CommandHistory to somewhere in System (System-Support, perhaps), and * leave resetAllHistory in MorphicExtras, perhaps with #forgetAllGrabCommandsFrom:. This doesn't fully resolve the issue, because SmalltalkImage &gt;&gt; #zapAllOtherProjects calls #resetAllHistory (among other dependency-on-MorphicExtras-causing actions), but does snip one more thread. What do you think? frank </pre> Frank Shearar 2013-05-22T11:46:24 http://permalink.gmane.org/gmane.comp.lang.smalltalk.squeak.general/169162 <pre> How bit this as a plan for breaking this particular dependency? * Add Object &gt;&gt; #localeChangedGently to System-Localization * For each of the classes mentioned in LocaleClass class &gt;&gt; #localeChangedGently (ParagraphEditor, BitEditor, and so on) implement a #localeChanged that calls self initialize * Use reflection to invoke these, something like this: localeChangedGently self environment allClassesDo: [:cls | cls localeChangedGently] but please suggest something nicer. I'm saying "self environment" here because we might well need different environments set to different locales. frank </pre> Frank Shearar 2013-05-22T08:13:36 http://permalink.gmane.org/gmane.comp.lang.smalltalk.squeak.general/169161 <pre>Frank Shearar uploaded a new version of System to project The Trunk: http://source.squeak.org/trunk/System-fbs.538.mcz ==================== Summary ==================== Name: System-fbs.538 Author: fbs Time: 22 May 2013, 7:51:50.831 am UUID: 62080650-696b-42a7-b576-79b849a51288 Ancestors: System-fbs.537 Make #actualClass work in any Environment.

Not in the sense of implementing the functionality directly, but in the sense that ToolBuilder-Morphic (etc) makes sure the various widgets behave in this manner. Tools that construct their UIs using ToolBuilder would then Just Work. MC browsers need to be rewritten to use ToolBuilder. However, that work is decoupled from making ToolBuilder-Morphic do this UI feedback thing right. frank </pre> Frank Shearar 2013-05-22T07:48:03 http://permalink.gmane.org/gmane.comp.lang.smalltalk.squeak.general/169158 <pre> On 21-05-2013, at 6:49 PM, David T.

With that in mind, I'd be inclined to focus on just one of these ideas and bring it to completion before taking on the next. IMO, the two-stage highlighting idea seems like something that would be a real benefit in terms of perceived responsiveness, so I'd vote for that one. Dave </pre> David T.

It's amazing how often writers of tools forget this and even more amazing how often the writers of UI widgets ignore any thought of providing a way to support the needed instant feedback. My rantette today particularly refers to what happens in the MC repository browsers but is generally applicable; even the plain old code browser ought to be getting it right but doesn't - it's just that on a fast machine you don't often notice that. On slower machines it can be so damn annoying people simply give up. I'd prefer that didn't happen. So, when you click on a package version the very first thing that should happen is the list item ought to be highlighted *right now*, before any start is made on the downloading of the package.
