Hi, Andy...
You need to subclass NSTableView and override the following method:
- (NSDragOperation)draggingSourceOperationMaskForLocal:(BOOL)isLocal;
From this method, you should return whatever NSDragOperation masks you
support. The default implementation returns NSDragOperationNone if
"isLocal" is not true. This means that it won't support dragging
outside of your application to any other application, including the
Finder.
HTH,

Hey all,
I have a simple NSTableView and I'm trying to make it so the user can
drag files into my list view and drag files out of it into the Finder.
I have the dragging from the Finder to my app working, but I can't
get the Finder to accept my drags.
Here's what my tableView: writeRows: toPasteboard: code looks like:
- (BOOL) tableView: (NSTableView *) tableView writeRows: (NSArray *)
rows toPasteboard: (NSPasteboard *) pboard
{
std::vector<ProjectFileRef>* files = mFiles;
NSMutableArray* fileNames = [NSMutableArray arrayWithCapacity: [rows
count]];
for(int i = 0; i < [rows count]; i++) {
int rowIndex = [[rows objectAtIndex:i] intValue];
ProjectFileRef fileRef = (*files)[rowIndex];
NSString* absolutePath =
ConvertCppStringToObjCString(fileRef.GetAbsolutePath());
[fileNames addObject: absolutePath];
}
[pboard declareTypes:[NSArray arrayWithObject:NSFilenamesPboardType]
owner:nil];
[pboard setPropertyList:fileNames forType:NSFilenamesPboardType];
return YES;
}
From the debugger I've verified that absolutePath is indeed a valid
file path, but the Finder wants nothing to do with my drag. Its not
even giving the drag feedback hilite. I can drag fine from within my
application (within the same list view or from document to document).
I'm probably doing something stupid, but I can't see it. Any pointers?
Thanks,
