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

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);
