MATLAB: Displaying files using a Listbox

guiguidelistbox

Using GUIDE, I have a listbox that I wish to use to display a folder of files, then have the user select a file from the box, then click another pushbutton to run the selected file. I was looking at http://www.mathworks.com/help/techdoc/creating_guis/f6-7446.html#f6-11263 but was confused where the path to the directory goes or how I add that.

Under the section Specifying the Directory, I see list_box('create','path_to_folder') but am unsure if that is what I'm looking for.

Thanks for the help

Is the folder of files you wish to display going to be hardcoded into the GUI, or do you wish to have the user select the folder too?

EDIT

Here is an example how to do this. The following code works on my machine. I think you will put the stuff which gets the directory name in the listbox createfcn or the figure creatfcn. I don't use GUIDE anymore so I may be wrong about that. Give it a try and let me know what happens. Note, I commended the lines of importance to your problem.

function [] = GUI_LST_DIR()
S.fh = figure('units','pixels',...
              'position',[500 500 200 260],...
              'menubar','none',...
              'name','GUI_1',...
              'numbertitle','off',...
              'resize','off');
D = dir('C:\Users\matt fig\Documents\MATLAB');  % Here put your dir name.
D = {D(:).name};
D = D(~cellfun('isempty',strfind(D,'m')));
S.ls = uicontrol('style','list',...
                 'unit','pix',...
                 'position',[10 60 180 180],...
                 'min',0,'max',2,...
                 'fontsize',14,...
                 'string',D);      % Populate the string with D. 
S.pb = uicontrol('style','push',...
                 'units','pix',...
                 'position',[10 10 180 40],...
                 'fontsize',14,...
                 'string','Run File',...
                 'callback',{@pb_call,S});
function [] = pb_call(varargin)
% Callback for pushbutton, runs the selected M-File
S = varargin{3};  % Don't worry about this in GUIDE GUI.
% Instead of S.ls, use GUIDATA to get handle to listbox
C = get(S.ls,{'string','value'}); 
mfl = C{1}(C{2});  % The M-File string name.
eval(mfl{1}(1:end-2))  % Run the M-File

Here is a simple example. More basic GUI examples can be found here.

function [] = GUI_pop_to_list()

MATLAB: GUI adding elements in listbox

This is from my collection of GUIs for learning on the FEX.

function [] = GUI_2()
% Demonstrate how to add a new entry to a uicontrol string.  
% Creates a listbox with some strings in it, an editbox and a pushbutton.  
% User types some text into the editbox, then pushes the pushbutton.  The 
% user's text will be added to the top of the listbox.
% 
% Suggested exercise:  Modify the code so that hitting return after a 
% string is typed performs the same task as pushing the pushbutton.
