Re: SpDropListPresenter emptyList

by Russ Whaley

Yes, me too- and be careful, thereâs no going back - lots of deprecated methods in v10. Plus, for me, Iâm on MacOS Mojave. v10 wouldnât run - they fixed it so v10 runs - but now v9 wonât run for me, soâ¦ Iâm migrating to v10!

Re: SpDropListPresenter emptyList

by Robert Briggs

I just had a look at the method in P10.Â And one line of code is added to the emptyList method.Â I copied it to p9 and it no longer throws the exception.Â I will continue to look to see if there are further differences I need to âback-portâ ( or perhaps I just need to download the latest version of Spec2.

SpDropListPresenter emptyList

I think this might be a bug. When I send emptyList to a non-empty SpDropListPresenter it reports âSubscriptOutOfBounds: 1â. I seems to be due to emptyList setting the list model to a new empty OrderedCollection and a later method trying to access the first item in the collection.

Of course, you should first know what encoder is being used, after that, it is easy to use a different encoder. Consider: '/tmp/foo.txt' asFileReference readStreamEncoded: #utf8 do: [ :in | in upToEnd ]. '/tmp/foo.txt' asFileReference readStreamEncoded: #windows1252 do: [ :in | in upToEnd ]. '/tmp/foo.txt' asFileReference readStreamEncoded: #latin1 do: [ :in | in upToEnd ]. ZnCharacterEncoder knownEncodingIdentifiers. #windows1252 asZnCharacterEncoder. If you could post a small example of your file, I could try to help. It will probably be #windows1252 or #latin1. HTH, Sven

Illegal Leading Byte

by craig

Hi Guys, I'm reading a text file which is supposed to be ASCII encoded. This file contains a list of filepaths and was created by a Python program. Well, it turns-out that file names on Windows can contain illegal UTF-8 characters. This causes ZnUTF8Encoder to signal 'Illegal leading byte for utf-8 encoding' and crash the program. I would like to handle this situation more elegantly, is there a more appropriate code-page to use for the Windows filesystem? Craig

Re: The orange 'content modified' indicator

by Esteban Lorenzano

Re-hi :) Not because something was used before is good :) As I said, spec does not handles the concept of "dirty". Also, it does not has the concept of "accept" (accept what? what is dirty? within what context?). Knowing that is something that depends on your application. Editors, for example tend to put an asterisk in the name (and maybe a "mod" string in the status bar)... this is for example more friendly with colorblind people. I do not doubt the triangle was useful for you, but this is a punctual solution for a punctual problem, not a generic mechanism. Still as I said, you can easily implement something that would match your needs within your application. We do not have an "add triangle" style, but you can add/remove a style changing the border, you can hide/show an icon, whatever you want. There was someone in the community doing his own version of "controls with model" with spec (I do not remember who). I guess you need something like that, where you can keep the status of your model and know if something is dirty and how to react to that. Not hard to implement in a reusable way.
