Yes not sure what caused it. I have just copied a table and its
datasource from another part of my project, which also has a checkbox
and it also works fine in my sheet. I'm now gradually changing the
datasource to what I want for this table. So far so good.
So problem solved - but I'm not sure what caused the original weirdness.

Hi, I write a simple project, and put a NSTalbeView in the window,

controller is as following:

return 128;

- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:
(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex

return [NSNumber numberWithInt:1];
}
@end
it works fine.

Subject: Weird NSTableView with checkboxes issue
I have an NSTableView in a sheet window. It has one column and a
valid dataSource and delegate. There are 128 rows. If I populate
the view with Textcells, sliders or popup button cells the
tableview scrolls normally, but if I populate the listbox with
checkbox cells the scrolling becomes extremely jerky. In the
datasource objectValueForTableColumn method I just do the following:
id)tableView:(NSTableView *)tableView objectValueForTableColumn:
(NSTableColumn *)tableColumn row:(int)row{
return [NSNumber numberWithInt:0];
}
my datasource/tableview is copied from another project that does
exactly the same thing and it scrolls just fine. The console/
debugger etc. show nothing is amiss.
Any suggestions what may be causing the problem?
Thanks!
Peter
