[vwnc] working with image files on Mac OS X

I'd like to interact with Quartz and/or Core Image libraries on the Mac. Does anybody have experience with this from VisualWorks?

I only need to interact with the file system, showing thumbnails of image files (possibly many of them, so I guess this would be performant only using the native Mac image handling libraries), being able to select them and know the selected file in VW.

Any pointers are appreciated.

You could simply use a native file dialog. This even offers cover
flow, filtering and sorting at no extra cost. Use OjectiveCConnect to
connect to class NSFileOpenPanel.

Re: [vwnc] working with image files on Mac OS X

sounds like an interesting approach. I do not want a modal dialog however, but a constantly open view of the filesystem, and knowing in Smalltalk which file(s) are selected, and from within Smalltalk modify the file names or copy and move files.

The most ideal would be (I guess) to embed the NSFileOpenPanel in a Smalltalk window. Don't know if that will work and how to achieve it. I have done this extensively on Windows but never on Mac.

I will try to find out how this might work, but if anyone has a bit more examples or information I will be much obliged.

Ah, I see. I do similar things with a customized NSFileOpenPanel
implemented with Cocoa (XCode). You may want to compile a framework
and link that to Smalltalk via DLLCC. The code isn't cross-platform
anyway.

In my case the panel notifies Smalltalk about selection changes, then
Smalltalk opens the file and displays its properties in the customized
accessory view of the panel (the panel stays open all the time). This
way I have a native file dialog that allows for browsing files by
their content details before opening.

However, the native panels are always modal. I don't think you can
change that easily.
