outlineView(_:shouldEdit:item:)

Returns a Boolean value that indicates whether the outline view should allow editing of a given item in a given table column.

Declaration

@MainActor optional func outlineView(_ outlineView: NSOutlineView, shouldEdit tableColumn: NSTableColumn?, item: Any) -> Bool

Parameters

  • outlineView:

    The outline view that sent the message.

  • tableColumn:

    The table column.

  • item:

    The item.

Return Value

true to permit outlineView to edit the cell specified by tableColumn and item, false to deny permission.

Discussion

If this method returns true, the cell may still not be editable—for example, if you have set up a custom NSTextFieldCell as a data cell, it must return true for isEditable to allow editing.

The delegate can implement this method to disallow editing of specific cells.
