After doing a bit more work with this and finding myself completely
lost, I've concluded that C programming at this level is out of my
depth. So I won't be pursuing it further.

| Hi Jim,
|
| I've done a bit more digging into this question about native icons,
| including recompiling Tk with "icns" replacing "cicn" in the
| tkMacOSXBitmap.c file. That yields no change, I still can't load any
| native icons. However, I noticed that the icon bitmaps in this file all
| seem to be based on resource files (cicn, ICON): that's also what you
| indicated. But aren't resource files more or less obsolete on Tiger?
|
| I loaded the "tclresource" extension (for dealing with resource files
| under OS X) into Wish and here is the output of a few operations:
|
| % resource open ~/Desktop/Wish.icns
| file does not contain resources in any fork
|
| % resource list
| %
|
| The "icns" file has no resource data at all, as far as I can see. And,
| at least based on what the extension tells me, there are no loaded
| resources running in memory.
|
| That would explain why loading "-bitmap application" into a label, for
| instance, returns white space: it's looking for a resource file (cicn?)
| and not finding any. Because "application" is defined as a native bitmap
| in tkMacOSXBitmap.c, calling the "-bitmap application" reference doesn't
| return an error.
|
| I've even tried resetting Tk to use QuickDraw instead of CoreGraphics,
| as the "cicn" resources are based on QD, correct? Still nothing.
|
| At this point, my conclusion is that the code in tkMacOSXBitmap.c needs
| to be updated--as to how, I'm not sure yet. I am going to look at the
| Icon Services API more closely to try to understand this better. What
| would be ideal is for Tk to be able to read .icns as native bitmaps, so
| that a command such as [image create bitmap foo -file foo.icns] would
| "just work." I don't know how or where the .icns file format is
| documented, however, and will have to delve into that as well.
|
| Whether my work on this will take the form of a patch to
| tkMacOSXBitmap.c or a separate "tkIcns" extension remains to be
determined.
|
| Any advice is appreciated.

| | Well, a quick perusal of the developer documentation shows this API:

| |

generating
| | a Tcl/Tk wrapper for accessing system icons, if there isn't already  the
| | capability to do so in Tk Aqua.
| |
| | Basically, I want to be able to browse a directory, i.e. glob, and
| | automatically call the correct bitmap as defined for the system for a
| | specific file or folder. I don't want to do a lot of hacks converting
| | system icons to .gifs or .pngs, which is what I'm doing now in the  code
| | I'm playing with.
| |
| | Jim or Daniel, is this something that would be useful? A "TkIcns"
| | package perhaps? Or is there a way programatically to do this already?
