Hello,
I have an outline view with a column with an NSButtonCell in it. I want to make
that button invisible and inactive for all outline rows. Here is my code for
the ouline view's delegate:
- (void)outlineView:(NSOutlineView *)outlineView willDisplayCell:(id)cell
forTableColumn:(NSTableColumn *)tableColumn item:(id)item
{
if ( ! [item isLeaf] )
{
if ( [[tableColumn identifier] isEqualToString:@"toReconnect"] )
{
[cell setEnabled:NO];
[cell setTransparent:YES];
}
}
}
setEnabled works on single cells, and as expected: the outline row's button is
grayed out. Oddly, setTransparent affects all cells in the column, i.e. the
button appears in no row, not even the ones that have no children.
That's confusingly inconsistent, to me. What should I do to make invisible only
the checkboxes in the row that have a twirly triangle?
Thanks,
Rainer
