20// This class functions as an adapter from a RemoveRowsTableModel to a Cocoa
21// NSArrayController, to be used with bindings.
22// It maps the CanRemoveRows method to its canRemove property, and exposes
23// RemoveRows and RemoveAll as actions (remove: and removeAll:).
24// If the table model has groups, these are inserted into the list of arranged
25// objects as group rows.
26// The designated initializer is the same as for NSArrayController,
27// initWithContent:, but usually this class is instantiated from a nib file.
28// Clicking on a group row selects all rows belonging to that group, like it
29// does in a Windows table_view.
30// In order to show group rows, this class must be the delegate of the
31// NSTableView.

44// title for a group row, usually the first column. If the model doesn't have
45// groups, it can be nil.
