listbox.m

I ve made an aplication in matlab using GUI, where you can load an image(.jpg) and a file (.txt).

function varargout = Listbox(varargin)
% LISTBOX M-file for Listbox.fig
%      LISTBOX, by itself, creates a new LISTBOX or raises the existing
%      singleton*.
%
%      H = LISTBOX returns the handle to a new LISTBOX or the handle to
%      the existing singleton*.
%
%      LISTBOX('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in LISTBOX.M with the given input arguments.
%
%      LISTBOX('Property','Value',...) creates a new LISTBOX or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Listbox_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Listbox_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

% --- Executes just before Listbox is made visible.
function Listbox_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 Listbox (see VARARGIN)

% Choose default command line output for Listbox

% UIWAIT makes Listbox wait for user response (see UIRESUME)
% uiwait(handles.figure1);


% --- Outputs from this function are returned to the command line.

% varargout  cell array for returning output args (see VARARGOUT);

% eventdata  reserved - to be defined in a future version of MATLAB

% --- Executes on button press in pushbutton1.

% --- Executes during object creation, after setting all properties.

% 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.
