Hi, Tried several solutions found in the forum but none of them worked, in my program, when a cell is selected, all the info of the row is displayed in different edit cases, when the cell in the uitable is edited and enter is pressed, the wanted value changes properly but the CellSelectionCallback is called again and the indices this time are inexistent and returns an error. Any way of fixing this? Thanks in advance

Yes, here is the code

function uitable2_CellSelectionCallback(hObject, eventdata, handles)                
% hObject    handle to uitable2 (see GCBO)
% eventdata  structure with the following fields (see MATLAB.UI.CONTROL.TABLE)
%  Indices: row and column indices of the cell(s) edited
%  PreviousData: previous data for the cell(s) edited
%  EditData: string(s) entered by the user
%  NewData: EditData or its converted form set on the Data property. Empty if Data was not changed
%  Error: error string when failed to convert EditData to appropriate value for Data
% handles    structure with handles and user data (see GUIDATA)
matriz = handles.dia;
indices = eventdata.Indices;
handles.edit2.String = num2str(matriz(indices(1),1));    
handles.edit3.String = num2str(matriz(indices(1),2));    
      if matriz(indices(1),3) < 0                              
          valor = matriz(indices(1),3) + 24*3600;                   
          set(handles.checkbox1,'value',1);                            
      else
          valor = matriz(indices(1),3);                             
          set(handles.checkbox1,'value',0);                            
      end
      horas = floor(valor/3600);                                       
      resto = rem(valor,3600);
      minutos = floor(resto/60);
      if minutos == 0
          handles.edit4.String = strcat(num2str(horas),':','00');      
      else
          handles.edit4.String = strcat(num2str(horas),':',num2str(minutos));  
      end
      if matriz(indices(1),4) < 0                             
          valor = matriz(indices(1),4) + 24*3600;                    
          set(handles.checkbox2,'value',1);                             
      else
          valor = matriz(indices(1),4);                              
          set(handles.checkbox2,'value',0);                             
      end
      horas = floor(valor/3600);                                        
      resto = rem(valor,3600);
      minutos=floor(resto/60);
      if minutos == 0
          handles.edit5.String = strcat(num2str(horas),':','00');      
      elseif minutos <10
          handles.edit5.String = strcat(num2str(horas),':','0',num2str(minutos));
      else
          handles.edit5.String = strcat(num2str(horas),':',num2str(minutos));  
      end
handles.edit6.String = num2str(matriz(indices(1),5));        
handles.edit7.String = num2str(matriz(indices(1),6));
% set(hObject,'Enable','Off');
guidata (hObject,handles);

This is used in case the user selects a cell, a series of edits will display the information of the row in the matrix but if i change what's contained in the cell and press enter, it re-enters the CellSelection and gives an error without refreshing the value.

Nice. I posted the rest as an answer so that this question is marked as solved.

Noah 2023-12-27

Hi - this simples way to do is just to "refresh" the "Data" field;

% Refresh the "Data" field" to its own = Unselect

handles.my_tbl.Data = handles.my_tbl.Data;

Following the comments under the question, we've arrived to the answer.

For some reason, pressing enter after entering data in a UItable activates your cellselectionCallback (which isn't the case when I try it using a simple UI table in 2018a).

When your cellSelectionCallback is activated after pressing enter, the indices are empty.

The real solution would be to prevent the unnecessary callback in the first place but without playing around with your entire GUI I cannot do that remotely.

The alternative solution is to escape from the callback function when the indices are empty.

Insert this at the top of your cellSelectionCallback function.

if isempty(eventdata.Indices)
  return
end

function [] = DeselectCellinUItable()

%---------------------------------------------------------------

uif = uifigure();

uif.Units = 'normalized';

uif.Position = [0.10, 0.50, 0.80, 0.40];

%---------------------------------------------------------------

uit = uitable(uif);

uit.Units = 'normalized';

uit.Position = [0.10, 0.50, 0.80, 0.40];

uit.Data = cell2table(num2cell(rand(10,7)));

uit.RowName = 'numbered';

uit.ColumnEditable = true;

uit.SelectionType = 'cell';

uit.Multiselect = 'off';

uit.SelectionChangedFcn = @(src,event) DeselectUItable;

%---------------------------------------------------------------

function DeselectUItable

uit.Selection = [];

end

%---------------------------------------------------------------

end
