Spec2 Pharo8/9; icons

Dear all,

What would be the best Pharo version to start building a Spec2 GUI for an app - Pharo 9 which is under development but with novelties in Spec2, or Pharo 8?

What's the best (easiest ...) way to import new icons into Smalltalk ui icons? Is there any special bitmap format to be considered?

Thanks and best wishes,

Tomaz

Re: Spec2 Pharo8/9; icons

Hello Tomaz

Dear all,

What would be the best Pharo version to start building a Spec2 GUI for an app - Pharo 9 which is under development but with novelties in Spec2, or Pharo 8?

I would go for P9. It may be a bit shaky from time to time but for example you can milestoned your image and if the next one is shaky you wait.

We are always developing in bleeding edge so eating our own dog food (and p9 has been nice so far).

Just now we got Spec20 0.6 and it contains many improvements.

I hope to be able to start to code some mini tutorial (learning myself and writing what I’m learning).

What's the best (easiest ...) way to import new icons into Smalltalk ui icons? Is there any special bitmap format to be considered?

png is better and there is a library to manage icons

I do not have the name but you can load icons.

But look around.

Thanks and best wishes,
Tomaz

Thanks, Stephane, I'll switch to P9.

For icons I found the necessary code in ThemeIcons>>loadIconsFromUrl. Here's a simplistic approach to load icons from PNGs in a local ZIP archive, if somebody needs it:

| themeIcons newIcons |

newIcons := IdentityDictionary new.
themeIcons := ThemeIcons new.

((FileSystem zip: 'C:\icons\a.zip' asFileReference)
open workingDirectory allChildrenMatching: '*.png') do:
[ :each | newIcons
at: each base asSymbol
put: (themeIcons readPNGFrom: each )].
newIcons.

Best wishes,

Re: Spec2 Pharo8/9; icons

thanks for sharing. I will add it to the chapter Tips of the new book on Spec20 :)

I remember also that there is a project to manage icon sets.

Hi,

> I remember also that there is a project to manage icon sets.

I found the library - it's ImageForm
(https://github.com/pablo1n7/ImageForm). If you use it, there's no need to
use ThemeIcons>>#readPNGFrom:.

The above code becomes:

To make this example complete:

Re: Spec2 Pharo8/9; icons

I'm sorry, the raw tag at forum.world.st ate the code :-)

| newIcons |

newIcons := IdentityDictionary new.
((FileSystem zip: 'C:\icons\a.zip' asFileReference)
open workingDirectory allChildrenMatching: '*.png') do:
[ :each | newIcons
at: each base asSymbol
put: (ImageForm open: each )].

SpToolBarButton new
label: 'Go!';
icon: (newIcons at: #iconFileName).

Re: Spec2 Pharo8/9; icons

In recent spec2 (head) we added support so that an application can have an iconProvider so it means that you can

using the ThemeIcons load and manage a set of icons for your application.
