> FT is FastTable. This is a project begun by Esteban to replace the old slow list on Pharo. > Pharo 5 uses FastTable now. Thanks for the details. Should I update to Pharo5 tu use FT ? As for my progress in debugging things. I see that the roots and the children behave differently (although they are created equal by my nodeFromTreeStructure: method), for instance, root nodes are not inspectable, when I try to see them in an inspector I get : MessageNotUnderstood SpecTreeNodeModel>>gtInspectorMorphIn. Children nodes can be seen in the inspector without a hitch. Also, root nodes know their widget (a MorphicTreeNodeAdapter) whereas the children return nil. Any help, even just a reference at someplace to look, would be appreciated. On Mon, 26 Oct 2015 at 11:49 Ferlicot D.

Re: [Pharo-users] fast subclassing/class creation in tests

by Peter UhnÃ¡k

Thanks Nicolai, the suspension seems to have quite a significant performance impact. Out of curiosity I did some benchmarking. Although the numbers seems to vary a lot based on something (the size of the image jumped from 25 to 40MB after I was done... and there seems to be some correlation with the performance). Repeatedly running a benchmark seems also detrimental as the performance can drop by over 30%... so probably it would be best to run each benchmark in a completely new image... However the fact that the performance decreases over time is problematic, because that means that running the test suite will get worse over time. I find it also peculiar to see that unlogged anonymous classes are faster when the announcer is NOT suspended. And while for classes the improvement was ~40x, for methods it was over 200x faster... so I guess the best way is to modify performTest behavior to something like ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ MyTestClass>>performTest SystemAnnouncer uniqueInstance suspendAllWhile: [ super performTest ] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Benchmarks (I've removed decimal parts and thousand separators because they are always confusing me): Class creation with announcer: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ [ |cls| cls := Object subclass: #Something. cls removeFromSystem. ] bench. "'9 per second'" [ |cls| cls := Object subclass: #Something. cls removeFromSystemUnlogged. ] bench. "'173 per second'" [ |cls| cls := Object newAnonymousSubclass. cls removeFromSystem. ] bench. "'4 per second'" [ |cls| cls := Object newAnonymousSubclass. cls removeFromSystemUnlogged. ] bench. "'512 per second'" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Class creation without announcer: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ [ SystemAnnouncer uniqueInstance suspendAllWhile: [ |cls| cls := Object subclass: #Something. cls removeFromSystem. ] ] bench.

"'368 per second'" [ SystemAnnouncer uniqueInstance suspendAllWhile: [ |cls| cls := Object newAnonymousSubclass. cls removeFromSystemUnlogged. ] ] bench.

Re: [Pharo-users] How to store an image file as a method source

by Peter UhnÃ¡k

I use IconFactory (which I wrote for this purpose) ( http://smalltalkhub.com/#!/~peteruhnak/IconFactory or Catalog Browser ), it works in the same way as Pharo icons (base64 representation of the image which is then converted to a Form object). Catalog browser offers also ExternalIconFamily but I have no knowledge of that. But I remember that someone was working on referencing external files, so maybe this is it.

Re: [Pharo-users] How to programatically select an item in a Spec TreeModel ?

by Edouard KLEIN

What is FT ? I did some debugging. When I send the selected:#true message to a root node, it goes down to the Morphic classes, and everything is fine, when I send it to a child node, the dependents array of the TreeNodeModel is nil, so nobody gets the message. I don't know enough about Spec yet to understand what dependents are and why there are none on a child node. Because I really need to get this done quickly, I will try to write a quick and dirty fix in a subclass that will directly talk to the morphic objects underneath. Now, with some guidance from you guys, I would be really happy to take some time and write some useful code that could solve this problem correctly, and have it commited for anyone to use. But first, in order to justify to my employer that coding with Pharo was a good choice, I need to make my application work. I'll update here as I go.

How to store an image file as a method source

by Dimitris Chloupis

So how you guys covert image files to strings to be stored as method sources ? I want to make a custom GUI that will contain a lot of images and I am a bit on a dilema whether I should put the images as method source as we do already with pharo icons OR just link to external files and find how I can download those files from Pharo. No idea whats the best course of action . Any suggestions ?
