Make selected row bold in NSTableView

Question

I try to make bold row selection style in NSTableView without any highlighting

I switched highlighting off:

[myTable setSelectionHighlightStyle:NSTableViewSelectionHighlightStyleNone];

However I have some troubles making text bold in selected row. As I suggested, I need to change properties of NSTableView's source:

- (void) tableViewSelectionDidChange: (NSNotification *) notification
{
    NSDictionary *boldFont = [NSDictionary dictionaryWithObject:[NSFont boldSystemFontOfSize:13.0]
                                                         forKey:NSFontAttributeName];
    NSDictionary *normalFont = [NSDictionary dictionaryWithObject:[NSFont systemFontOfSize:13.0]
                                                         forKey:NSFontAttributeName];

    for(MyClass *obj in tableSourceList)
        obj.name = [[NSMutableAttributedString alloc]
                           initWithString:obj.name
                               attributes: normalFont];

    long row = [myTable selectedRow];
    MyClass objectAtSelectedRow = [tableSourceList objectAtIndex: row];
    objectAtSelectedRow.name = [[NSMutableAttributedString alloc]
                            initWithString:dr.dreamname
                                attributes: boldFont]; 
    [tableSourceList replaceObjectAtIndex:row withObject:objectAtSelectedRow];
}

Unfortunately, there's no effect.

How to make text in row bold when selected?

Answer 1

You can try to achieve by altering the table cell to be rendered in the table's delegate:

- (void)tableView:(NSTableView *)aTableView willDisplayCell:(id)aCell forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex {
    // Maybe a test on the table column is recommanded if some cells should not be modified
    NSIndexSet *selection = [aTableView selectedRowIndexes];
    if ([selection containsIndex:rowIndex]) {
        [aCell setFont:[NSFont boldSystemFontOfSize:12]];
    } else {
        [aCell setFont:[NSFont systemFontOfSize:12]];
    }
}
