I have already found this solution... But thank you anyway.

I don't believe that nobody here knows how to do that.
Maybe I do.
I did it for an NSOutlineView. Shouldn't be any difference for a table
view.
I subclassed the outline view with the followig code:
- (void)draggedImage:(NSImage *)anImage endedAt:(NSPoint)aPoint
operation:(NSDragOperation)operation {
NSPoint mousePoint = [NSEvent mouseLocation];
NSPoint winPoint = [[self window]
convertScreenToBase:mousePoint];
NSPoint viewPoint = [self convertPoint:winPoint fromView:nil];
// if the drag session ended in the same outline view
// do nothing
if (NSMouseInRect(viewPoint, [self visibleRect], [self
isFlipped])) {
}
// the drag ended outside the view
else {
if( [[self dataSource] respondsToSelector:
@selector(removeEntry:)]) {
// code for sound and a poof animation
// iterating through dragged items and removing them from
// the data source
NSEnumerator *enumerator = [[[self dataSource] draggedEntries]
objectEnumerator];
id entry;
while (entry = [enumerator nextObject]) {
[[self dataSource] removeEntry:entry];
}
// update GUI
[self reloadData];
}
}
}
Hope it helps.
Chears,
Joern
