Problem with data of uitable

Question

0 个投票

Hello I am working in a interface where a button displays a figure which contains a table with some data, I created the table with this code

t = uitable('Position',[20 50 260 100],'Data', d,...
'ColumnName', columnname,...
'ColumnFormat', columnformat,...
'ColumnEditable', [false true true],...
'RowName',[],'CellEditCallBack',@editTable_Callback,'Tag','Tabla1','HandleVisibility','Callback');

But when I try to retrieve the data as

get(handles.Tabla1,'Data')

it shows me an error

Reference to non-existent field 'Tabla1'.

Also if I look at handles it does not appear the handles of the table I created

I appreciate your assistance

since you're coding the uitable instead of using GUIDE you do not have the handles structure. you already have the handles for the uitable assigned to t.

so you just need to go get(t,'data').

the tag works differently when not using GUIDE as it is not also the same name as the GUI item. since you manually assign it to t you should know what item you're referring to. the tag is useful if you need to search for it but right now i cannot get a good instance when you need to. but to find the handles of the uitable if you do not have it you can find it by using the line findall(0,'tag','Tabla1')

Thanks Joseph I do not know if you can help me with another issue. if I try to change a value on the table i want to update the data in the position of t (Table) and save that information to use later in another function

function editTable_Callback(hObject,callbackdata,handles)
% hObject    handle to pb (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
r = callbackdata.Indices(1);
c = callbackdata.Indices(2);
if c==3
    d=struct2cell(callbackdata);
    dato=d(4,1);
else
    dato=eval(callbackdata.EditData);
end
hObject.Data{r,c} = dato

This function is supposed to change the data in the position and the if is because c that is the column in the third position is a popupmenu and I use this to convert to a char and the others I storage them as doubles but what I saw is that t value is not updating.

I appreciate your help

Thanks
