I've got an NSTableView that displays (via bindings) data from an NSTreeController. The application frequently appends/changes data to/in the bound array.
The problem is that if the user has selected a row in the table, but has scrolled so that the selected data is no longer visible, when the application updates the array it causes the display to auto-scroll so that the selected line is once again on screen. This is pretty frustrating to users, especially since new data can arrive at any time.
Is there any way of disabling this feature?
You may have to subclass NSTableView and override -scrollRowToVisible:, temporarily bracketing the call to super. This may also require a custom BOOL ivar in your subclass to keep track of whether you want to scroll.
I would start by setting a breakpoint there to see when exactly the autoscroll is triggered. This should help to find the proper moments to toggle the ivar.
