I have a an NSTableView when ever I click on a specific header column the data in the table get reversed or sort upside down. I have checked NSTableView
as well as NSTableColumn
but couldn't find any method that disables this. I would be obliged if anyone can help in disabling this sorting on clicking on the header of a particular column.
Sorting of the NSTableView
is done by its sortDescriptors
, see here.
An NSTableColumn
uses its sortDescriptorPrototype
(see here) to generate the sort descriptor of the NSTableView
, depending on how many times you clicked the column header, etc.
If you use dataSource
to manage the data, then the sort descriptor is communicated via the delegate method tableView:sortDescriptorsDidChange:
, see here. You just need to ignore the change message to stop sorting.
If you use Cocoa bindings to manage the data, the sort descriptor is generated by the table column and set to the NSArrayController
. To stop it, just open the inspector of the binding of the table column, select value
, and uncheck "Creates Sort Descriptor."
