如何在Matlab指南列表框中使用动态数据列表

% --- Executes just before your_guide_name is made visible.
function your_guide_name_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to your_guide_name (see VARARGIN)

% Choose default command line output for your_guide_name
handles.output = hObject;

% Initialize dynamic data list
handles.dynamicList = {'Item 1', 'Item 2', 'Item 3'};

% Bind dynamic data list to listbox
set(handles.listbox1, 'String', handles.dynamicList);

% Update handles structure
guidata(hObject, handles);

% --- Executes on button press in updateButton.
function updateButton_Callback(hObject, eventdata, handles)
% hObject    handle to updateButton (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Update dynamic data list
handles.dynamicList = {'Item 4', 'Item 5', 'Item 6'};

% Bind updated dynamic data list to listbox
set(handles.listbox1, 'String', handles.dynamicList);

% Update handles structure
guidata(hObject, handles);

% --- Executes on selection change in listbox1.
function listbox1_Callback(hObject, eventdata, handles)
% hObject    handle to listbox1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get selected item index
selectedIndex = get(hObject, 'Value');

% Perform operation based on selected item index
switch selectedIndex
    case 1
        disp('Selected Item 1');
    case 2
        disp('Selected Item 2');
    case 3
        disp('Selected Item 3');
    otherwise
        disp('Invalid selection');
end

% --- Executes during object creation, after setting all properties.
function listbox1_CreateFcn(hObject, eventdata, handles)
% hObject    handle to listbox1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called

% Hint: listbox 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');
