Re: [Pharo-project] How to know 'real' extent of a PanelMorph

by Gary Chambers

Try #minExtent, though that won't cater for things with scrollbars. Perhaps worth re-implementing #optimalExtent to deal with those. Regards, Gary ----- Original Message ----- From: Cyrille Delaunay To: pharo-project Sent: Friday, May 20, 2011 2:34 PM Subject: [Pharo-project] How to know 'real' extent of a PanelMorph Hello, I have a panelMorph composed by several row/columns with different kind of morphs. What I would like to know is, what is the extent / size that I should use to FULLY display this panel (without scrollbars). Each time I ask for the extent of a panelMorph, it answers 50@40, whatever what is inside. If you openInWorld you will have something very very small. Is there a way to retrieve an extent with which the panel morph will be 'well' displayed (without having scrollbars everywhere)? In other words, what I really want to know is: Given two panelMorph, is there a way to say that one need more place than the other to be displayed?

Re: [Pharo-project] Tiling windows

by laurent laffont

On 1.2: Gofer it squeaksource: 'LaurentLSandbox'; version: 'Polymorph-Widgets-LaurentLaffont.388'; load. Then open or move a window so the TaskBar is updated and you have a new "magic" button on bottom left. (note this is hacky actually, I will write a nicer version this week if people like it).

[Pharo-project] Complete MethodContext stack for testing

by Mariano Martinez Peck

Hi guys. We need to do some test to serialize a MethodContext to a file, materialize it, and then compare it to the original. One of the problems we face is that some values in the MethodContext are changed so it is difficult to test. So...what we would like is to get a "bottom" MethodContext that we can ask #sender, and to that one #sender, and like that....and the whole stack should cannot be changed. Another problem is that I cannot do a #deepCopy on a MethodContext because #basicNew: throws errror. Is this possible? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] What happens with named primitives in CM ?

by Mariano Martinez Peck

Hi folks. I was inspecting for example the CM of Integer >> #bitAnd: and the first literal is an array like this: #(#LargeIntegers #primDigitBitAnd 0 17) I understand the first and the second elements, but I don't the third and the fourth. What are they? (0 and 17) because then even seem to change their value. I am asking because I am serializing CompiledMethod and then at materialization time I am putting just two zeros for the moment. But I am not sure what they mean. Thanks in advance, -- Mariano http://marianopeck.wordpress.com

Hi rafael Thanks for helping for the translation. are in the spanish speaking mailing-lists? I will probably do a lecture before the esug conference at edinburgh. Are you planning to attend ESUG?

This is easier to do Smalltalk in a group. If you look at the SmalltalkParty, i organize several times in Paris. We start with maybe less than 10 people at the beginning and after several years, we were more than 40 ... Create also a Smalltalk mailing-list if there is none in Spain.
