This is a question about the sample that was posted here last October, at

http://lists.squeakfoundation.org/pipermail/beginners/2006- October/001238.html

I am not able to make it work. I was able to file in the code and start an instance from a workspace with 'SampleImageViewerMorph new.' I click on the 'dir' button in the upper left hand corner of the resulting Image Viewer Morph window, and that summons a directory browser UI that I can navigate to a directory that has jpgs in it. ( e.g., "C:\Documents and Settings\wades\My Documents \My Pictures\rocks5"). When I hit the 'accept' button in the directory browser, it goes away and the path to the directory I picked goes into the location bar or whatever you'd call it in the Image Viewer Morph window. A balloon comes up, saying 'When I'm populated, you can click on a file to load it.' Nothing happens.

If I try hitting the little '>' button by the location bar on the Image View Morph window, I get an "error out of bounds." If I debug that, I see that the error happens in SampleImageLoader>>loadImage: it appears that the SampleImageLoader's collection members are empty.

I tried making an instance of SampleImageLoader from the workspace, thinking I could manually initialize it and load the image list.

a _ SampleImageLoader new. a inspect. (open a transcript) a loadImagesBelow: 'c:\stuff\rpics' The transcript shows "Entering DosFileDirectory on 'c:\stuff \rpics'" and then nothing else happens.

Should any of this work?

I am using:

Squeak3.9 latest update: #7067 Current Change Set: Unnamed1 OK

On WinXP SP2. _______________________________________________ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners

I file the code and could see is working.

SampleImageViewerMorph new on a Workspace Or select the class in the Sustem Browser and alt - click for "more" and then "sample instace"

Could be enhanced to read all the picts formats and not only jpg.

Hints: Go to Utilities >> graphicsFileSuffixes. Investigate "senders" Have fun !

I got SampleImageLoader's loadImagesBelow working: the problem was that it was trying to match files ending with .jpg or .jpeg, but my files had .JPG.

I still am having problems with the package though. It appears that the SampleImageLoader is not getting hooked up with the Model correctly.

Are you using 3.9?
