Hi,
I use [NSWorkspace sharedWorkspace] iconForFile:filePath] to get
the 128x128
icon of a file or a folder. It works well, but it is amazingly
slow. It get
the icon in about 1 second, much more that getting a thumbnail of a
large
jpg file by CGImageSourceCreateThumbnailAtIndex.
Is a faster way, even an old carbon way, working on Tiger and Leopard?
Best Regards

Well, on my machine (G4 DP 1.25Ghz 1 Gig RAM)), it takes 0.002
seconds to do it. There is something else happening in your case I
reckon.
Here's my complete IBAction:
- (IBAction)chooseFile:(id)sender
{
NSOpenPanel *panel;
NSString *chosenFile;
int result;
NSString *title = @"Choose the file";
NSString *okButtonTitle = @"Choose";
panel = [NSOpenPanel openPanel];
[panel setCanChooseDirectories:YES];
[panel setCanChooseFiles:YES];
[panel setAllowsMultipleSelection:NO];
[panel setTitle:title];
[panel setPrompt:okButtonTitle];
result = [panel runModalForDirectory:nil file:nil types:nil];
NSLog(@"time 1");
if (result == NSOKButton) {
chosenFile = [panel filename];
NSImage *aImage = [[NSWorkspace sharedWorkspace]
iconForFile:chosenFile];
[myView setFileIcon:aImage];
[myView setSize:NSMakeSize(128.0,128.0)];
[myView setNeedsDisplay:YES];
[slider setFloatValue:128.0];
[currentSize setStringValue:@"128"];
}
NSLog(@"time 2");
}
