Re: NSTableView, adding a NSImage in the cell

Hi,

You want to use an NSImageCell I believe... Basically... In your
awakeFromNib you want to get the right table column, and set it's data cell
to be an NSImageCell, (sort of like this)

NSTableColumn* theColumn =
        [mTableView tableColumnWithIdentifier:@"SubScript"];
[theColumn setDataCell:[[NSImageCell alloc] initImageCell:nil]];


You cold do this in two places - if you are using a custom NSTableView then
you can stick this in it's awakeFromNib, or alternatively, you can do it in
the window controller's awakeFromNib (which is where I did it in this bit of
code... I've actually done both)

Then, in your

- (id)tableView: objectValueForTableColumn: row:

Delegate method, you want to return the image for the right column...

Eg

- (id)tableView:(NSTableView *)tableView
objectValueForTableColumn:(NSTableColumn *)tableColumn row:(int)row {
    NSString* ident = [tableColumn identifier];
    if ([ident isEqual:@"SubScript"])
    {
        return [[[self script] itemAtIndex:row] image];
    }
    // else if... Etc...
}

Hope this helps ;-)
