How to set background color of cell with NSButtoncell type in NSTableView?

问题

This is my table view delegate:

- (void)tableView:(NSTableView *)tableView willDisplayCell:(id)aCell forTableColumn:(NSTableColumn *)tableColumn row:(int)row
{
    id theRecord;
    NSMutableString *gid;

    theRecord = [tableDataSource objectAtIndex:row];
    gid = [theRecord objectForKey:@"gid"];

    if (([gid intValue] % 2) != 0)
    {
        [aCell setDrawsBackground: YES];
        [aCell setBackgroundColor: [NSColor colorWithCalibratedRed: 237.0 / 255.0
                                                             green: 243.0 / 255.0
                                                              blue: 254.0 / 255.0
                                                             alpha: 1.0]];

    }
    else
    {
        [aCell setDrawsBackground: NO];
    }
}

It works fine to display normal cell but the tableview get frozen after I add a cell with NSButtonCell type (for checkbox). How to fix it ?

Any help would be appreciated.

回答1:

According to the NSButtonCell reference, you can only specify a background color for borderless buttons. Have you tried to use borderless button cells ?

Moreover, I cannot find setDrawsBackground: method for NSButtonCell; I can only find it for NSTextFieldCell. Have you tried to remove the call ?
