Thread Subject: connecting 2 GUIs

I want to call a gui (built by codes) using a push button in
another gui (built by guide) but I get this error:

Output argument "XYfinal" (and maybe others) not assigned
during call to "C:\Documents and
Settings\Ibo\Desktop\GUI\domain_definition.m
(domain_definition)".

Where is the problem?

Try using the function uiwait.

The .m file domain_definition.m should get and return the
handle of figure that it creates.

  fig = domain_definition;

  ...
   
  uiwait(fig)
  ...

We have no idea where the problem is (and I believe the other
posters suggestion of uiwait() is irrelevant to the problem.)

Your function domain_definition is not assigning a value to all
of its output arguments (the names before the '=' in the 'function'
line), but the calling routine has an output variable in the
corresponding position and so requires that the value be defined
by the function.

domain_definition.m is not provided by Matlab, so we have no idea
what the code in it looks like, and no idea what the routine is
intended to do. You also did not provide any context code, so we
do not have any idea what arguments you are passing when you
invoke domain_definition().

It is as if you asked us, "I named my car Frodo. The
trouble light comes on in the car. What is the problem?" without
giving us any information about the make or age of the car or how
you had been driving it or its repair history, or any odd noises
you had been hearing, or any steering problems, etc., and you are
expecting us to be able to tell you "Oh, you must have a 1968
Ford Fiesta, and when you make the left hand turn and start going
up a hill that is between 1.8 and 2.1 kilometers away from where you
started the car, the car is warning you that you are low on
brake fluid in the front-right brake."

You wrote the code; you've told us essentially nothing about it;
we can't tell you *why* the problem is occuring! Read your code!
Put in breakpoints and trace the code and figure out *why* you
are not assigning a value to XYfinal.

Thanks for the reply
Mesh_console is my main GUI and domain_definition is a gui
that when the user pushes a push button on the main gui is
called.

the code was working well but when I developed the
domain_definition gui and had to use the handle of its
figure in the code this error started

I tried to handle with the way that you told but I think
when we create gui with guide it's a bit different.

The hanlde of domain_definition is my_h and now the main gui
says that the my_h is unknown. How can I introduce this
handle to the main gui?

Here is the code for domain_definition. This gui should be
called by a push button in mesh_console gui and trasnfer the
XYfinal (coordinates of xy) to mesh_console when we select 4
points on it.
The code works very well by itself:

function [XYfinal]=domain_definition

my_h=figure('Name','Input_Using_GUI',...

    'WindowButtonDownFcn',@clickButtonDown,...
    'WindowButtonMotionFcn',@buttonMotion,...

The variable my_h should be defined in the output.

function [my_h, XYfinal]=domain_definition
 my_h=figure('Name','Input_Using_GUI',...
     'Numbertitle','off',...
     'WindowButtonDownFcn',@clickButtonDown,...
     'WindowButtonMotionFcn',@buttonMotion,...
     'Position',[100 100 700 600]);

I have done this before but I again gave it a try and again
got the same error message. I think my_h by itself cannot be
recognized by the main GUI.

FYI the call back function is:

% --- Executes on button press in pb_input_using_GUI.
function pb_input_using_GUI_Callback(hObject, eventdata,
handles)
% hObject handle to pb_input_using_GUI (see GCBO)
% eventdata reserved - to be defined in a future version of
MATLAB
% handles structure with handles and user data (see GUIDATA)

[my_h,XYfinal]=domain_definition;
[coordinates]=auto_nomination(XYfinal);


    set(handles.xA,'String',coordinates(1));
    set(handles.yA,'String',coordinates(2));
    set(handles.xB,'String',coordinates(3));
    set(handles.yB,'String',coordinates(4));

Hello Huy,

I ONLY add uiwait(my_h) before
clickButtonDown(varargin)function and it worked as what I
wanted. We did not need to add the function to the main
function. You're the man, thanks!!!

uiwait(my_h);
function clickButtonDown(varargin)

But I am wondering how we can add our own function to a GUI
created by GUIDE, I tried it sometimes but it always failed.

Addressing only the last part of your discussion, you should
be able to add any function you'd like at the bottom of the
main GUI code generated by GUIDE. Alternativly if you used
the "property editor" to change the 'tag' property of the
buttons you created in GUIDE to what you'd like the callback
function to be named, GUIDE will automatically adjust the
callback function accordingly.
