POPMENU cb1 and IUTABLE: UITB1

1 I have: POPMENU cb1 and IUTABLE: UITB1

 in the object POPMENU  desire to click each option and need the object IUTABLE is full.

 Each option object  POPMENU a different data in IUTABLE. (Data: Data1, Data2, Data3)

[Geoff Hayes]

Dany - please clarify what you need help with. Are you just trying to populate the table with data that is dependent upon the item selected in the popup menu?

[Dany León]

YES, IN MENU HAS 3 OPTIONS FOR EACH OPTION THE "uitable" OBJECT IS FILLED WITH A DIFFERENT DATA

Dany - if you want to fill the uitable with a different set of data given the selection in the popup menu, then you will need to create a callback for the popup menu and have it respond to the user selection. Something like

 function popupmenu1_Callback(hObject, eventdata, handles)
 % hObject    handle to popupmenu1 (see GCBO)
 % eventdata  reserved - to be defined in a future version of MATLAB
 % handles    structure with handles and user data (see GUIDATA)

 % Hints: contents = cellstr(get(hObject,'String')) returns popupmenu1 contents as cell array
 %        contents{get(hObject,'Value')} returns selected item from popupmenu1

 % get the index of the selected value (from the menu: 1, 2, or 3)
 selectionId = get(hObject,'Value');

 % populate the table with a different set of data depending upon the selection
 switch selectionId
    case 1
        set(handles.uitable1,'Data',1*ones(4,4));
    case 2
        set(handles.uitable1,'Data',2*ones(5,5));
    case 3
        set(handles.uitable1,'Data',3*ones(6,6));
 end

Note how we use use handles to update the uitable (named uitable1). The above is just a simple example which you should be able to fit for your needs. Try it and see what happens!

Thanks a lot Geoff. I have a data with 3 attributes, in the following path load ('C:\data.mat'); I can not load the data. Where I should put the code?

[Geoff Hayes]

Dany - the code to load the file would be in the pop up menu callback. What do you mean by can not load the data? Are you observing an error or some other problem?

[Dany León]

Data loading is not possible to uitable. Doesn't recognize the data "data" in the workspace

function cb1_Callback(hObject, eventdata, handles)

load ('C:\data.mat','data1','data2,'data3');

selectionId = get(hObject,'Value');

switch selectionId

      case 1
        set(handles.uitb1,'Data',data1,'ColumnNane',colummname);
      case 2
        set(handles.uitb1,'Data',data2,'ColumnNane',colummname);
      case 3
        set(handles.uitb1,'Data',data3,'ColumnNane',colummname);
  end

Error

Undefined function or variable "data1".

Error in Myfig>cb1_Callback (line 87)

Error in gui_mainfcn (line 95)
        feval(varargin{:});
Error in Myfig (line 42)

      gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata) Myfig 
('cb1_Callback',hObject,eventdata,guidata(hObject))

[Geoff Hayes]

Dany - there are a handful of bugs in the above code. The line

 load ('C:\data.mat','data1','data2,'data3');

is missing a single quote around data2 and so should be replaced with

 load ('C:\data.mat','data1','data2','data3');

The local variable colummname is undefined, and the property 'ColumnNane' is incorrect and should be 'ColumnName'.

I was able to create a simple example that is very similar to yours, and I can load the uitable. Please make the above corrections and try again. Also, put a breakpoint in the cb1_callback and step through the code to see what the problem might be.

Geoff Hayes thanks a lot
