Error when getting selected cell indices - R2019b

Hi,

I'm running into an error when using the cell selection callback for a uitable. Below is how i have defined the callback function, the function and the error message i am getting.

classdef PFTable < Component
    properties
        Table
    end
    
    methods    
        function obj = PFTable(model, parent, varargin)
            obj@Component(model, parent);
            obj.Table = uitable('Parent', obj.Panel);
            obj.Table.CellSelectionCallback = @(s, event) obj.setToSelectedCell(obj);
            obj.set(varargin{:});
        end
    end
    
    methods (Access = protected)
        function setToSelectedCell(obj, event)
            indices = event.Indices;
        end
    end
end

The error message i get is

Unrecognized method, property, or field 'Indices' for class 'PFTable'.

Error in PFTable/setToSelectedCell (line 69)
            indices = event.Indices

Error in PFTable>@(s,event)obj.setToSelectedCell(obj) (line 13)
                obj.Table.CellSelectionCallback = @(s, event) obj.setToSelectedCell(obj);
 
Error using matlab.ui.internal.controller.uitable.WebMWTableController/handleEvent (line 588)
Error while evaluating Table CellSelectionCallback.

Am i getting this error because the access to the function is protected?

Any advice on how to get the callback working would be great!

Hi i've got the answer solved,

classdef PFTable < Component
    properties
        Table
    end
    
    methods    
        function obj = PFTable(model, parent, varargin)
            obj@Component(model, parent);
            obj.Table = uitable('Parent', obj.Panel);
            obj.Table.CellSelectionCallback = @obj.setToSelectedCell;
            obj.set(varargin{:});
        end
    end
    
    methods (Access = protected)
        function setToSelectedCell(obj,~,e)
            indices = e.Indices;
        end
    end
end

            obj.Table.CellSelectionCallback = @(s, event) obj.setToSelectedCell(obj);

You are not passing the event into the method.

When i update the callback to this

obj.Table.CellSelectionCallback = @(s, event) obj.setToSelectedCell(obj, event);

I get this error

Error using PFTable/setToSelectedCell
Too many input arguments.

Error in PFTable>@(s,event)obj.setToSelectedCell(obj,event) (line 13)
            obj.Table.CellSelectionCallback = @(s, event) obj.setToSelectedCell(obj,
            event);
