why does GUIDE not save components handles

M-file code:

function pushbutton1_Callback(hObject, eventdata, handles)
handles.myValue=999;
disp(5);
disp(handles);

If start this code from M-file by F5 button, the command windows shows:

 5
        figure1: 173.0032
    pushbutton1: 179.0032
          axes1: 174.0032
         output: 173.0032
        myValue: 999

But if start by double clicking the .fig file, command window shows only:

 5
        myValue: 999

In Matlab HELP it is said: "When the GUI is fully initialized, the handles structure contains only handles to all the components in the GUI and custom data added in any CreatedFcn callbacks and/or the OpeningFcn."

but at the same time I see error messages about missing fields in the handles structure while my gui program is running.

For example this code:

function pushbutton1_Callback(hObject, eventdata, handles)
axes(handles.axes1);
plot(rand(5));

will work well ONLY if start it from M-file with F5 button, or if create the handles.axes1 MANUALY like this:

function axes1_CreateFcn(hObject, eventdata, handles)
handles.axes1=hObject;
guidata(hObject, handles);

Otherwise Matlab displays an error: "Referring to non existing field handles.axes1"

I was sure that the GUI handle structure would consist handles to all added in GUIDE components as it is said in HELP. In result, relying on this, I waste so much time finding reason for that "non existing filelds" messages. May be

This is why you never run a GUIDE GUI from the figure.

Always run the *.m file associated with it. This creates all of that stuff and does the initializations.

What if I need to make .exe? sorry, but you suggestion sounds like not to use things if you don't know how .

[Sean de Wolski]

If you need to make an executable, use the *.m file as the entry-point or main file. The *.fig file should packaged automatically based on the dependency analysis and then the *.m file will be run.

The *.fig file with a GUIDE GUI is literally just a figure with no intelligence. The *.m file gives it that intelligence which is why it needs to be run..

[Alexandr Troshchanovskii]

Thank you very much Sean! You really helped me to understand the things.

.. now I understood that all the initialization data is in the *.m file that's why I must start it first.
