Hi all,
I have a table view with all columns bound to keys of an
NSArrayController.
The array controller implements some data source methods, mainly for
drag and drop support.
One of the columns uses an NSImageCell to display 32 x 32 icons.
Scrolling the table view vertically gets very slow if the icons's
column is within the table view's visible portion.
Surprisingly, it gets a lot faster if I implement -
tableView:objectValueForTableColumn:row: in the data source (= the
array controller).
- tableView:objectValueForTableColumn:row: returns the value for
the corresponding key, which is exactly the same key as used by the
bindings.
The table view doesn't show this behaviour for its other columns
which use the default data cell (NSTextFieldCell).
Any ideas what might be going on here?
Nice weekend to everybody,
Peter
