Error running GUI outside of GUIDE

Hi,

I designed a UI using GUIDE, such that the push button allows me to select a file from a folder and a list box displays the name of the file. I proceeded to run it (run figure in GUIDE) and it worked.

The issue here is when I close GUIDE and open the .fig file. In this case, it returns the error shown:

??? Reference to non-existent field 'listbox3'.

Error in ==> mlp_gui>sel_out_dat_Callback at 84
set(handles.listbox3,'String',handles.outputdata)

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> mlp_gui at 42
    gui_mainfcn(gui_State, varargin{:});

Error in ==>
@(hObject,eventdata)mlp_gui('sel_out_dat_Callback',hObject,eventdata,guidata(hObject))

??? Error while evaluating uicontrol Callback

My guess for this error is that the handle for the listbox was not created in the case where I operated the UI outside of GUIDE?

Any suggestions to correct this will be helpful.

Thanks!

Are you trying to run the m-file associated to the fig-file? You have to run the .m file in order to run your GUI.

( Right click on m-file -> run )

( Type in command window the name of the m-file (no-extension needed) )

Hi David,

No, I'm not. I'm trying to get the GUI itself (i.e. .fig file) to work. In my case the GUI (.fig) works when I run it from the m-file or GUIDE. But once I close both and try to run .fig on its own it fails.

On the other hand, are you saying that I cannot run the GUI using just the .fig file? That I would need to prompt it using the m-file instead?

Thanks.

Click GUI icon on toolbar or Type GUIDE in Command Window... Then GUI window opens.... Click Open Existing GUI... Open the GUI created by you... Then RUN

Hi Ravi,

Thanks for the help, but this isn't the issue.

I tried running the GUI (.fig) by clicking on it in the Current folder window and it failed, but it was ok when I tried running (debugging) it in the m-file or GUIDE.

Please advise.
