Hi! > If you're heading to make "Roassal the best visualizing engine of the Universe" then what are your intentions with connecting it to the outer world ? This is a rather broad question :-) While our visualizations are meant to run in a standard Smalltalk environment, they are exportable to HTML. Interaction are also preserved. Here are two simple examples: https://dl.dropboxusercontent.com/u/31543901/TMP/memoryBlueprintExample.html <https://dl.dropboxusercontent.com/u/31543901/TMP/memoryBlueprintExample.html> https://dl.dropboxusercontent.com/u/31543901/online/WebReport/seisms.html <https://dl.dropboxusercontent.com/u/31543901/online/WebReport/seisms.html> And a larger and more complex example is in the file https://dl.dropboxusercontent.com/u/31543901/TMP/ExampleReport.zip <https://dl.dropboxusercontent.com/u/31543901/TMP/ExampleReport.zip> check the file Example.pillar.html > Will it remain a multiplatform toolbox ? Or are you heading towards a BI desktop or Web app ? Roassal will remain closely linked to Smalltalk (VisualWorks & Pharo).

Unique Mouse Wheel Events
by Sean P. DeNigris March 23, 2015

March 23, 2015

Cross-posted to Pharo dev, Squeak dev, and Squeak VM lists (but Pharo list rejected so I am reposting there separately)... Recently, we discovered on the Pharo dev list that the key combination used to fake wheel events - ctrl + arrowKey - may be a bit too simple. Apparently ctrl+horizontalArrowKey is a standard in-use combo in Linux and Windows, so adding horizontal wheel events broke some users' workflows. So I propose "ctrl + alt + shift + cmd + arrowKey". The new combo is: very unlikely to be typed backward-compatible with existing Pharo and Squeak images, which only checks that either cmd or ctrl is pressed frees up ctrl + arrow for our Linux/Windows friends For Pharo, there is: https://github.com/pharo-project/pharo-vm/pull/72 Fogbugz Issue 15209: "Mouse Wheel Events Keyboard Clash", with a slice all ready on the image side once the VM patch is integrated. NB: I changed the combo in the VM for Mac OS and OSX. Are these the only two platforms that fake wheel events? I searched a bit but didn't see similar logic for other platforms... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Unique-Mouse-Wheel-Events-tp4814475.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Re: [Pharo-dev] [Moose-dev] Re: The Grapher charting engine

Yes. Although RTDevVarDecorator is not rooted into strong maths. It was more an experiment. If you look at the class RTDevVarDecorator, you will see it is quite simple. Adding decoration in a chart made with Grapher is very simple.

Color arithmetical operations are broken
by Aliaksei Syrel March 22, 2015

March 22, 2015

Hi, I played with colors and found out, that arithmetical operations with colors are completely broken. https://pharo.fogbugz.com/f/cases/15188/Color-ariphmetical-operations-are-b… Result is not a valid Color - just garbage. It happens because alpha is not being initialized and stays nil. It seems that operation were implemented before alpha support was added. So I propose the following solution: Color red - Color red = Color transparent (Color white alpha: 1) - (Color white alpha: 0.5) = (Color white alpha: > 0.5) R,G,B are subtracted as before. Alpha channels are subtracted too. Color red + Color blue = Color magenta Color red + Color transparent = Color red (Color white alpha: 0.5) + (Color white alpha: 0.5) = (Color white alpha: 1) > R,G,B are added as before. Alpha channels are added too. Multiplication and division by number doesn't change alpha channel. Cheers, Alex
