how to make passing parametes between GUI and *.m files

%================== in my gui file 
mygui.m
-------

function pushbutton1_Callback(hObject, eventdata, handles)

   [filename, pathname] = uigetfile({'*.avi';'*.mpeg'}, 'Pilih Video');
   set(handles.edit1,'string',[pathname filename]);
   guidata(hObject, handles);

   %call my 'myfile.m'
   mymfile

%================== in my *.m file
mymfile.m
-------

function obj = setupSystemObjects()

   urlfiles = get(handles.edit1,'string');
   obj.reader = vision.VideoFileReader(urlfiles);

how to passing '[pathname filename]' in 'handels.edit1' to variabel 'urlfiles' in my 'mymfiles.m' cause i still get error.

"The class "handles" is undefined. Perhaps Java is not running."

Fitroh - why not just pass the list of videos to your setupSystemObjects function (which is presumably saved to a file called setupSystemObjects.m and not in myfile.m) as an input parameter? Change the signature and body of this function to

 function obj = setupSystemObjects(videoFiles)

 obj.reader = vision.VideoFileReader(videoFiles);

 % etc.

and then call this function from your callback as

 function pushbutton1_Callback(hObject, eventdata, handles)

 [filename, pathname] = uigetfile({'*.avi';'*.mpeg'}, 'Pilih Video');
 videoFiles = [pathname filename];
 set(handles.edit1,'string', videoFiles);
 setupSystemObjects(videoFiles);

Try the above and see what happens! The alternative is to use global variables, but that is something that can be avoided here.
