This is a question about the sample that was posted here last October, at
http://lists.squeakfoundation.org/pipermail/beginners/2006-October/001238.ht...
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.

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 !

Hi Wade, Edgar,
I wrote that sample application, so I'm sorry you had problems getting it working. As you worked out, it's fussy about the (number, and case of) file extensions it recognises. I've fixed those issues and uploaded a new version, as I'm sure that this will have caused other people problems too.
Edgar - you mentioned that you'd have done things differently. I started writing a more complex application, but realised that image handling on my Mac wasn't very fast, so I stripped the application back down, but thought it was useful to document what I'd produced as I had a lot of trouble getting to a core SystemWindow-based application. Are you saying that (i) using SystemWindow is not the approach you'd have taken, or (ii) that's not how you'd have implemented a SystemWindow-based application? (or both!).
I'd appreciate any comments you have, and may add them to the application as warnings to anyone who picks it up in future.
Thanks, Michael

I send a attached of some old thing I do for showing how a slide show of picts could be made to some Squeaker.
Don't take me as last word ! I sure many could do same better.
but realised that image handling on my Mac wasn't very fast,
On which Mac ? How many picts ? I curious

I do a PasteUpMorph container of all picts. But could be done as SystemWindow and using layout. When I have time I try to redo the demo , this time SystemWindow based and recursive. I have one folder with 1117 picts from my cousins trip to Italy... Clear to manage this kind my PasteUpMorph approach is not good. Maybe a modification of BookMorph (as MiStack ) with cards holding say 50 picts each and flipping the cards ...
Keep Squeaking and having fun !

Thanks, it's always good to see how someone else addresses the same problem.

1Ghz G4 PowerBook. Loading of pictures is very slow (eg > five seconds per image IIRC) compared to the same code running on my work machine. That's why I added in background loading and caching of images.

I'd not thought of that approach, could be very useful
