Question

How can I change the color of a cell in my NSTableView?

Answer 1

//for VIEW based TableViews using Objective C
//in your NSTableViewDelegate, implement the following
//this customization makes the column numbers red if negative.
- (NSView *)tableView:(NSTableView *)inTableView
   viewForTableColumn:(NSTableColumn *)tableColumn
                  row:(NSInteger)row
{
    NSTableCellView *result = nil;
    if ([tableColumn.title isEqualToString: @"Amount"]) {
        //pick one of the following methods to identify the NSTableCellView
        //in .xib file creation, leave identifier "blank" (default)
         result = [inTableView makeViewWithIdentifier:[tableColumn identifier] owner:self];
        //or set the Amount column's NSTableCellView's identifier to "Amount"
        result = [inTableView makeViewWithIdentifier:@"Amount" owner:self];
        id aRecord = [[arrayController arrangedObjects] objectAtIndex:row];
        //test the relevant field's value
        if ( aRecord.amount < 0.0 )
            [[result textField] setTextColor:[NSColor colorWithSRGBRed:1.0 green:0.0 blue:0.0 alpha:1.0]];
    } else {
        //allow the defaults to handle the rest of the columns
        result = [inTableView makeViewWithIdentifier:[tableColumn identifier] owner:self];
    }
    return result;
}
