I wanted to do that already. Thanks for the directory names. Do you have an url where Apple discusses such directories? > Or better allow us to chnage the directory That's on my todo. As always, I need help. This is the kind of change people can do easily (the preference mechanism is already in place). So, if you want to hack on the launcher, this would be a good start. > The icons are odd, trying to get a new Pharo 3 image it says hit refresh > icon which took me some time to find.

I see 2 solutions: - have a menu item to refresh when right clicking on the "hit refresh button" message. - automatically download the content when expanding the tree. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Why won't my Pharo download run?
by PBK Research Nov. 7, 2013

Nov. 7, 2013

Hello! I have a problem with running Pharo 2.0 on one of my machines. I have two machines, both running Windows XP with SP3. On one of them I have a successful load of Pharo (actually it's a distribution of the Moose system, but that is just an application built on Pharo 2.0). This loads successfully when I double click on pharo.exe. On the other machine, the same action produces an immediate message: 'Pharo.exe has encountered a problem and needs to close'. Just in case this was some problem with Moose, I have just downloaded the latest one-click installation of Pharo 2.0 for Windows. This displays exactly the same behaviour - an immediate fail when I try to start it. I have tried to work out what may be different between the two machines. The one which will run Pharo has an Intel Celeron processor, the other an AMD Athlon XP (yes, they are both pretty ancient!), but I can't see why that should make any difference. The one curious thing is that Windows Explorer displays the type of the Pharo2.0.image file as 'Squeak image file'. There is an old version of Squeak installed on that machine; could that have any effect? I am a bit flummoxed by all this. Does anyone have any suggestions about how to diagnose the problem? Many thanks Peter Kenny

Spec - TextModel whenTextIsAccepted
by Bahman Movaqar Nov. 7, 2013

Nov. 7, 2013

Hi all, I'm writing a simple graphical version of the legendary "Hello, world". I have a window with a text field, a button and a label. What I'm trying to do is to make the button (which is initially disabled) enabled upon user entering text. However, it seems that the user first must "Accept" the text for the action to be fired. Here's some snippets of code: <code> initializePresenter textName whenTextChanged: [ buttonGreet enable ]. buttonGreet action: [ labelGreeting text: 'Hello, ', textName text, '!'. buttonGreet disable ]. initializeWidgets self instantiateModels: #( textName TextModel labelGreeting LabelModel buttonGreet ButtonModel ). labelGreeting text: ''. buttonGreet label: 'Greet Me!'; disable. </code> What am I doing wrong? TIA, PS: I have tried `whenTextChanged` to no avail --it shows the same behaviour. -- Bahman Movaqar (http://BahmanM.com) ERP Evaluation, Implementation & Deployment Consultant PGP Key ID: 0x6AB5BD68 (keyserver2.pgp.com)

Writing a GUI - Where to start?

Glad that it was usefull. Meanwhile HPDF is outdated (still on FFI, a port to NativeBoost would now be state of the art) and we also have Artefact for PDF generation as a "Pharo only" solution. One question: did you "hard code" the PDF layouts for the documents in the "lawsuitTracker" or what did you use to (quickly) define the report layouts? I would like to see some kind of general reporting engine in the future. Either a pharo based one or by using templates from existing engines (for instance JasperReports has a nice visual ui designer and layout templates are stored in XML files) With a future UIBuilder for PharoUI's, Seaside for Web-UI's and a (Pharo based) ReportingEngine Pharo could be an attractive solution to build business software... Thx T.

Re: [Pharo-users] I would rather pay for Smalltalkhub than use Github for free.

I see some very strong arguments against depending on github: - it is centralized infrastructure, essentially unsuitable for use with a distributed version control system; - it doesnât support working at the right granularity; - the smalltalk community is too small to have any influence on the directions github is taking. It is a commercial organization that can decide to do something we donât like at any time. It is free, so we are the product. Just take a look at sourceforge; - we can do much better than github (but donât have enough time). We should be using a P2P, bittorrent like system for version control. Stephan

Hi Damien, I tried your .dmg file on my iMac running OS 10.9 (Mavericks). It didn't work. The error message is "Pharo.app is damaged and can't be opened." A second download and retry gave the same result.

Shortcut to "Browse Class"
by Bahman Movaqar Nov. 5, 2013

Nov. 5, 2013

Hi all, As an absolute beginner, when using a workspace, most of the times I don't know the type of the value returned by a piece of code or its methods. So I have to select the value, right-click on it, from the menu (BTW is there a name for this menu?), select "Explore" and then select "Browse Class" or "Browse Full". Is there a shortcut to this functionality? TIA, -- Bahman Movaqar (http://BahmanM.com) ERP Evaluation, Implementation & Deployment Consultant PGP Key ID: 0x6AB5BD68 (keyserver2.pgp.com)
