Changes to Trunk (http://source.squeak.org/trunk.html) in the last 24 hours: http://lists.squeakfoundation.org/pipermail/packages/2015-June/008741.html Name: Morphic-mt.987 Ancestors: Morphic-cmm.986 Fixes a regression in scroll bars that "automagically" scrolled on mouse move due to the latest changes. Makes #wantsEveryMouseMove functional again and adds it to the EventHandler, too. It also duplicates the additional checks regarding mouse focus, submorphs, button down, etc. =============================================

BUG Automagic scrolling ?
by karl ramberg 03 Jun '15

03 Jun '15

In latest image the mouse seem to scroll sliders just by mouse over the scroll bar. It's a very unusual behavior, and I think I would like to opt out of it. Is there a preference or is this a bug ? Karl

Events in Morphic originate in a Hand, pass to a target morph, and are then dispatched by an EventHandler. EventHandlers support redirection of mouse and keyboard activity by specifying and independent recipient object and message selector for each of the possible events. In addition each eventHandler can supply an optional value parameter for distinguishing between, eg, events from a number of otherwise identical source morphs. The basic protocol of an event handler is to receive a message of the form mouseDown: event in: targetMorph and redirect this as one of mouseDownRecipient perform: mouseDownSelector0 mouseDownRecipient perform: mouseDownSelector1 with: event mouseDownRecipient perform: mouseDownSelector2 with: event with: targetMorph mouseDownRecipient perform: mouseDownSelector3 with: event with: targetMorph with: valueParameter depending on the arity of the mouseDownSelector. !

Ongoing development could then be done by anyone interested, and everyone would be free to use it. Absolutely. Please take it and use it in any way you think is worthwhile. I’d rather you packaged it in a way you think is useful than my trying to guess what it is you need. Everybody on your list is a better programmer than I am and I look forward to learning from what they decide to change. You have my unreserved permission do take the code and use it in any way that could be useful to you.

Bug: list filtering is acting on multiple lists at once
by Chris Muller 02 Jun '15

02 Jun '15

1) Standard TrunkImage, default preference settings. 2) Open a browser, select a class. 3) Select a method category. 4) Move mouse into methods list, but don't click. 5) Type a filter. Both the category list (which has keyboard focus) AND the list under the hand filtering simultaneously.

New Cog VMs available

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3365 CogVM source as per VMMaker.oscog-eem.1332/r3365 Newspeak Cogit: Fix the regression in implicit receiver sends caused by VMMaker.oscog-eem.1317 (fix to performance regression caused by using XCHG on x86). The implicit receiver cache uses SendNumArgsReg to refer to the cache object. Hence we must use TempReg for genPushRegisterArgsForNumArgs: in this case. So refactor to genPushRegisterArgsForNumArgs:scratchReg:, passing either TempReg or SendNumArgsReg as approprate. -- best, Eliot

New Cog VMs available

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3364 CogVM binaries as per VMMaker.oscog-eem.1331/r3364 General: Merge with Pharo (with VMMaker.oscog-EstebanLorenzano.1322). Changes are null to Squeak VM. Pulled in are conditionally compiled changes for directory & file creation (added ceration permissions) and to macro used to read image file (for iPhone). Cogit: Test the outerContext and method for sanity in the machine code closure value primitive(s). Spur must check to fail in the presence of forwarders. To support the primitive provide TstCqR support on x86 (already exists on ARM), and use it to implement genJumpImmediate: et al. Use the new genJumpImmediate: et al in various basic access primitives. Good for a 5%-10% increase in 0 tinyBenchmarks on Spur. Guard access to the inline cache tag in PICs in GC routines by inlineCacheTagsMayBeObjects. Spur: Spur must follow forwarders in machine code before it follows forwarders in stack pages (since stack page parsing examines methods). Further, closed PICs that refer to unmarked objects must be discarded in freeUnmarkedMachineCode. And closedPICRefersToUnmarkedObject: should guard against an immediate selector. -- best, Eliot
