Re: [Pharo-users] Red Exclamation in Nautilus?

by Johan Fabry

Hi Tim, just a quick response to one of your questions: if a class has a red ! in front of it, it means that there is no class comment.

Re: [Pharo-users] Building UI with Spec vs Pharo

by Johan Fabry

Hi Peter, Spec is a user interface framework that is meant to be able to create any kind of user interface. On the other hand Glamour is meant for browser-like user interfaces where there is a flow from one element to another. So the answer is: it depends on what you want to do. Could you tell us what is it that you are trying to build? On Jul 9, 2014, at 11:39 AM, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > Hi, > > what is the recommended framework for building UIs? As I understand it Spec should be able to handle pretty much anything, however Glamour has quite a lot of nice features and was recommended here http://forum.world.st/Roassal-amp-Spec-td4690745.html as a higher-level abstraction framework (albeit the issue here was mostly Roassal which as I understand is a non issue since there is Roassal2Spec package). However I haven't seen things like forms (text inputs, checkboxes, (radio)selects, buttons) or popups (yes/no confirmations, prompts) made in Glamour so I am unsure whether it is possible. > > Thanks, > Peter ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

Hi Tim The exclamation mark marks a class that does not have a comment.

Red Exclamation in Nautilus?

by Tim Mackinnon

Guys - it's been a while since I've used Pharo, and in 3.0 its come along with leaps and bounds. But I'm struggling to know what many things mean, and what the UI is telling me? Is it written up somewhere? I also quite quickly seemed to get into troubles with the new Nautilus browser where it gives me walkbacks and won't let me select things. I've started again with a new image and am trying again to do some simple things - and see if I can come up with the use cases. As a starting point - I've just created a new class, with a new Category name and the class has a red exclamation mark next to it. What does that mean? Also what is the difference between Add Class, and Add full Class in the context menu? I ended up just typing over the definition of an existing class as there is no flyover help for either of these to know what it does?

Building UI with Spec vs Pharo

by Peter UhnÃ¡k

Hi, what is the recommended framework for building UIs? As I understand it Spec should be able to handle pretty much anything, however Glamour has quite a lot of nice features and was recommended here http://forum.world.st/Roassal-amp-Spec-td4690745.html as a higher-level abstraction framework (albeit the issue here was mostly Roassal which as I understand is a non issue since there is Roassal2Spec package). However I haven't seen things like forms (text inputs, checkboxes, (radio)selects, buttons) or popups (yes/no confirmations, prompts) made in Glamour so I am unsure whether it is possible.

Re: [Pharo-users] How to download Pharo40?

by Yuriy Tymchuk

Hi Tim, if you want a 1-click thing, you can get it from: http://pharo.org/download There is no such thing available for Pharo 4 as itâs in a development stage and only experienced hackers use it. You can run Pharo with ./pharo-ui Pharo.image as described at http://get.pharo.org. Personally I download images themselves. You can launch them on Mac with double click. Maybe youâll be also interested in Pharo launcher: http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher Cheers!

Re: [Pharo-users] Using FFI

yes, FFI does not handle ** arguments.
