MATLAB: How to call a function into a pushbutton GUI

gui

Hello ,

I have a GUI with 3 buttons, and a list box.

I would like to update the listbox, when i press a button.

The listbox contents are mat files located in a specific folder.

Here the script of the listbox :

function listbox2_Callback(hObject, eventdata, handles) % hObject handle to listbox2 (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 listbox2 contents as cell array % contents{get(hObject,'Value')} returns selected item from listbox2 handles.output = hObject; global files global A

set(handles.listbox2,'string',{files.name}); guidata(hObject, handles); contents = cellstr(get(hObject,'String')); %returns listbox1 contents as cell array A=contents{get(hObject,'Value')}

guidata(hObject,handles)

I would like to call this function into the push button

For the moment in pushbutton, i have :

function pushbutton2_Callback(hObject, eventdata, handles) % hObject handle to pushbutton2 (see GCBO) % eventdata reserved – to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA)

global files files = dir(fullfile(pwd,'manoeuvres','Calage_*')); guidata(hObject,handles)

I tried lot a command in order to launch it in the push button but i cant work

How can i manage to do that?

Thx for your reply

OK, my bad , i did not used the good push button ...... :)

So its work with this script inside the pushbutton :

files = dir(fullfile(pwd,'manoeuvres','Calage_*')); set(handles.listbox2,'String',{files.name}); guidata(hObject, handles);

MATLAB: Create a popup menu based on dynamic data

Hi I spoke to someone and eventually figured it out so thank for your reply anyway. The data is stored in a cell array and i had a push button to select the data. But the problem was in defining the string to be used and not putting the correct thing in the callback part of the code. The code below is what seems to work.

% --- Executes on button press in pushbutton3.
function pushbutton3_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton3 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB


% handles    structure with handles and user data (see GUIDATA)

% Extract curve information
ci = handles.wlog.curve_info(2:end, 1);
handles.ci = ci;
% Update handles structure
guidata(handles.figure1, handles);
% Set popupmenu1 string for list
set(handles.popupmenu1,'string',ci)
% --- Executes on selection change in popupmenu1.
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
%data = evalin('base','ci');
data = guidata(handles.figure1);
set(hObject, 'String', data.handles.ci)
% --- Executes during object creation, after setting all properties.
function popupmenu1_CreateFcn(hObject, eventdata, handles)
% hObject    handle to popupmenu1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called
% Hint: popupmenu controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end

MATLAB: How to return the values of variables in GUI

Set varargout in the output function to whatever you want.

% --- Outputs from this function are returned to the command line.
function varargout = controlsuite_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
  global contents;  % Whatever variable you want....
  try
     fprintf(1, 'In controlsuite_OutputFcn\n');
    varargout{1} = contents;
  catch ME
    errorMessage = sprintf('Error in function controlsuite_OutputFcn.\n\nError Message:\n%s', ME.message);
    fprintf('%s\n', errorMessage);
    WarnUser(errorMessage);
  end
  return; % from controlsuite_OutputFcn

You can pass out more by setting varargout{2}, etc. Be sure to make contents global in the function where you assign it also.
