I am traveling down the QuickLook path ...
I have followed all directions but my code is not being called by
qlmange as evidenced here:
7/12/09 4:46:08 PM qlmanage[855] [QL] Thumbnailing /users/davidblanton/
Aibnb18.pes. Content type UTI: dyn.ah62d4rv4ge81a3px. Generator used:
None
7/12/09 4:46:08 PM qlmanage[855] [QL] Thumbnailing for /users/
davidblanton/Aibnb18.pes done (No image created).
Is there some known secret sauce not divulged in the docs?

What is the preferred method of showing a file preview (my unique

The Accessory View looks 'hooky' to use , I want the preview in the
next browser column.
If you can image your content to a JPEG and/or PDF, it's very easy
to add these as Quicklook thumbnails and previews to a document
package. That avoids the need to write a QL plug-in for your format,
and the Open panel and Finder and QL preview in the Finder will
display these directly.
You need to use particular names for these preview images - it's
given in the docs somewhere. Here's the code I use to add them in my
app (subclass of NSDocument):
- (NSFileWrapper*) fileWrapperOfType:(NSString*) typeName error:
(NSError**) outError
{
NSData* mainContent = [self dataOfType:typeName error:outError];
if( mainContent == nil )
{
if( outError )
*outError = [NSError errorWithDomain:kOrteliusErrorDomain
code:kOrteliusNoDataErrorCode userInfo:nil];
return nil;
}
NSFileWrapper* fw = [[NSFileWrapper alloc]
initDirectoryWithFileWrappers:nil];
[fw addRegularFileWithContents:mainContent
preferredFilename:kOrteliusFilePackageMainContentFile];
// add "Quick Look" preview folder:
NSFileWrapper* qlFolder = [[NSFileWrapper alloc]
initDirectoryWithFileWrappers:nil];
[qlFolder setPreferredFilename:@"QuickLook"];
[fw addFileWrapper:qlFolder];
[qlFolder release];
// add preview and thumbnail
NSData* preview = [[self drawing] thumbnailData]; // JPEG
data
if( preview )
[qlFolder addRegularFileWithContents:preview
preferredFilename:@"Thumbnail.jpg"];
preview = [[self drawing] pdf]; // PDF data
if( preview )
[qlFolder addRegularFileWithContents:preview
preferredFilename:@"Preview.pdf"];
return [fw autorelease];
}
