Post Date: 01/12/2015 Partout oÃ¹ des dÃ©cisions critiques doivent Ãªtre prises, Thales est prÃ©sent. Sur les marchÃ©s que nous servons -Â aÃ©ronautique, espace, transport terrestre, sÃ©curitÃ©, dÃ©fenseÂ -, nous assurons la maÃ®trise de la Â« chaÃ®ne de dÃ©cision critique Â» pour aider nos clients Ã choisir la meilleure option et Ã agir en consÃ©quence. Lâexpertise de sesÂ 65 000 collaborateurs, sa puissance technologique et sa prÃ©sence opÃ©rationnelle dansÂ 56 paysÂ font ainsi de Thales un acteur clÃ© de la sÃ©curitÃ© des citoyens, des infrastructures et des Etats. <> La Global Business Unit SystÃ¨mes de Mission de DÃ©fense, leader europÃ©en et troisiÃ¨me acteur mondial sur ses marchÃ©s par sa taille et son niveau technologique, conÃ§oit des Ã©quipements et des systÃ¨mes de mission pour avions, hÃ©licoptÃ¨res et drones militaires, bÃ¢timents de surface et lutte sous la mer. Elle propose Ã©galement une offre complÃ¨te de services de maintenance en condition opÃ©rationnelle. Thales SystÃ¨mes AÃ©roportÃ©s, filiale du Groupe Thales (3200 collaborateurs) regroupe diffÃ©rents domaines dâactivitÃ©s : systÃ¨mes de mission pour avions de mission et drones, Radars aÃ©roportÃ©s de combat et surveillance, SystÃ¨mes de Guerre Electronique (air, terre, mer, espace), Soutien et Service Client. Dans le cadre de notre dÃ©veloppement, nous recherchons un(e) : STAGE : Multi-fenÃªtrage sous Pharo Smalltalk (Logiciel) â H/F BasÃ©(e) Ã Brest (29) Contexte : Notre entitÃ© dÃ©veloppe rÃ©guliÃ¨rement des maquettes dâinterfaces homme-machine (IHM) innovantes. Lâinnovation se situe autant au niveau de lâergonomie quâau niveau du design graphique visuel ou des Ã©lÃ©ments dâinteraction. Le maquettage est souvent utilisÃ© en sÃ©ance avec les opÃ©rationnels, dâoÃ¹ lâemploi dâun langage dynamique comme Smalltalk qui permet la modification rapide (et en sÃ©ance) du code et des Ã©lÃ©ments dâinteraction. Le maquettage/prototypage des interfaces Homme-Machine est donc actuellement rÃ©alisÃ© sous SMOCK, un framework de maquettage dÃ©veloppÃ© en Smalltalk. Smalltalk Pharo est un excellent candidat pour la plateforme finale d'exÃ©cution du framework de maquettage/prototypage, cependant, certaines limitations de Pharo nous empÃªchent de l'utiliser de maniÃ¨re industrielle. Missions : Nous souhaitons expÃ©rimenter un environnement de maquettage sous Pharo, cependant, cette derniÃ¨re limite lâaffichage des IHM Ã lâintÃ©rieur d'une seule fenÃªtre de l'OS. Nous souhaitons, en relation avec la communautÃ© Pharo, dÃ©velopper le multi-fenÃªtrage. Le stagiaire devra implÃ©menter un mÃ©canisme permettant l'ouverture et gestion de fenÃªtres multiples dans les OS Windows et Linux Ã minima. Une rÃ©utilisation de code existant dans la communautÃ© Pharo et une reversion de code en OpenSource est envisageable. Le candidat sera l'interlocuteur entre Thales et la communautÃ© Pharo. Le candidat Ã©valuera diffÃ©rentes solutions de multi- fenÃªtrage sous diffÃ©rents critÃ¨res (performance, robustesse de la solution, portabilitÃ© de la solution...). La solution devra anticiper le futur et prÃ©voir d'afficher des contenus visuels variÃ©s (vidÃ©o, primitives de dessin 2D, OpenGL...). L'objectif sera de dÃ©velopper un prototype IHM multi-fenÃªtres de dÃ©monstration sur Pharo afin de dÃ©montrer les nouvelles capacitÃ©s et un aperÃ§u des performances. Formation souhaitÃ©e : Master 2 Pro ou 3Ã¨me annÃ©e d'Ecole d'IngÃ©nieur. Connaissances souhaitÃ©es : Le stagiaire devra avoir une connaissance du Smalltalk ou Ãªtre motivÃ© par lâapprentissage de celui-ci. Il devra ensuite Ãªtre motivÃ© par la conception dâinterface homme machine de nouvelles gÃ©nÃ©rations et novatrices. PÃ©riode souhaitÃ©e et durÃ©e : Ã partir de janvier 2015 pour une durÃ©e de 6 mois.

Re: [Pharo-users] Pointer Detective - Inspecting an Object (instance) and Doing a "PointerDetective openOn: self." leads to a System Error in Pharo?

by Mircea S.

Joined Fogbugz. Managed to zero in closer to the issue. It seems the problem only happens with your latest commit (10) The one before that works as advertised. Also tried the latest commit on Squeak 4.5 All In One and on the latest Build of Pharo 4 and they both pop up a Debugger instead of the White Crash. Easy to replicate, even the example on the smalltalkhub page crashes it. Maybe there is some hardware difference, running a Retina mac on Yosemite, could this be it? (vm should be the same) Steps: Get Pharo 3 Open Monticello Add repository. Open repository. Choose latest commit (10) Load Open Workspace Paste in example and Do It -> White screen press esc to remove.

Editable text field inside Roassal/Trachel Canvas

by Peter UhnÃ¡k

Hi, is it possible to embed (any) editable text field inside Roassal? I managed to add the editor morph inside Trachel's athens canvas, however there is no way I can access it... my guess is that TRMorph takes all the events, or drawing the morph on the canvas destroys something. I tried it with PluggableTextFieldMorph (shows the border of the edit field, but no text), and TxTextEditorMorph (shows text). Is there any way around this? Adding the morph inside AthensWrapMorph works correctly, so my guess is that TRMorph must be doing something... perhaps I should also add it as a submorph of TRMorph somehow? My testing code follows: ------------------------------------------------ "opening the canvas and adding custom shape" trCanvas := TRCanvas new. text := SBEditableTextShape new. trCanvas addShape: text. trCanvas open. ------------------------------------------------ ------------------------------------------------ "content of SBEditableTextShape - same as the attachement" 'From Pharo4.0 of 18 March 2013 [Latest update: #40470] on 1 February 2015 at 10:13:04.069249 pm'!

Re: [Pharo-users] Seaside - How do I install Scriptaculous on a clean Seaside install (via Configuration Browser) on Pharo?

by Johan Brichau

You _can_ use Gofer to load individual packages, but the point of the Metacello configuration is that it will install the dependencies for you. So, itâs not a good idea to load them individually, unless you want to end up missing some prerequisite packages.
