I recently put together a sequence of interlinked NSTableViews using
checkbox cells.
It displays the mixed state without problem. So no bug I think.
I used a datasource in this case, as below.
- (id)tableView:(NSTableView *)aTableView
objectValueForTableColumn:(NSTableColumn *)aTableColumn row:
(NSInteger)rowIndex
{
// for the checkbox column
if ([scriptHandler count] == [scriptHandler publishedCount]) {
state = NSOnState;
} else if ([scriptHandler publishedCount] > 0) {
state = NSMixedState;
} else {
state = NSOffState;
}
return [NSNumber numberWithInt:state];
}
It doesn't matter if I do the
[myCheckBox setState:NSMixedState];
the result is the same, the checkbox is shown as checked.
If I however use the same code (or even click all the three states) in
an ordinary check box (not cell), everything works as I expect it to
do.
This makes me suspect this to be a bug.
