NSTableView issue

[Andreas Höschler]

Hello all,

I wondered why I could not select (Copy) a cell in a tableView in one 
of our apps. I finally found that thi sis due to

- (void) setDataSource: (id)anObject
{
  /* Used only for readability */
  const SEL sel_a = @selector (numberOfRowsInTableView:);
  const SEL sel_b = @selector 
(tableView:objectValueForTableColumn:row:);
  const SEL sel_c = 
@selector(tableView:setObjectValue:forTableColumn:row:);
  if (anObject && [anObject respondsToSelector: sel_a] == NO)
    {
      [NSException
        raise: NSInternalInconsistencyException
        format: @"Data Source doesn't respond to numberOfRowsInTableView:"];
    }

  if (anObject && [anObject respondsToSelector: sel_b] == NO)
    {
      [NSException raise: NSInternalInconsistencyException
                   format: @"Data Source doesn't respond to "
                   @"tableView:objectValueForTableColumn:row:"];
    }


  _dataSource_editable = [anObject respondsToSelector: sel_c];

  NSLog(@"setDataSource %@ %@ %d", anObject, 
NSStringFromSelector(sel_c), _dataSource_editable);
  /* We do *not* retain the dataSource, it's like a delegate */
  _dataSource = anObject;

  [self tile];
  [self reloadData];
}

_dataSource_editable being NO. I have not implemented 
tableView:setObjectValue:... in my data source, sincen I do not 
actually want ti edt the cells, but I wantto be able to select and copy 
from the columns I set to be editable. On MacOSX this works. A solution 
tomake this working on GNustep would be to implement the method in 
question and simply do nothing. But may be the SPEC sould be checked 
here. MacOSX at least behaves differently.

Regards,

  Andreas
