Getting datas from users with GUI interface

Hi everyone,

NOTE: You can find my code at the end of the post.

I am coding a function on Matlab which requires parameters from users. To do so, I first used the 'inputdlg' function. It worked quite well but in order to make it more user-friendly (and complex), I want to improve it with GUI.

First, I used GUIDE interface in order to create the layout. In this layout, I put a 'Push' button so that the user can :

1. Close the current window (layout);
2. Run the main program with those datas.

To sum up what I have done,

1. I decided to use 'uiwait' to let the user putting datas on the window;
2. Then, in the XXX_OutputFcn, I store all datas I need in a structure (called 's');
3. Put 's' in the varargout {1} in order to get the datas in my main function;
4. In the Push Button Callback function, I put uiresume and delete(handles.figure1) in order to close the window.

My questions and problems are:

1. Do I need to put variables I need in ONE structure in order to get only varargout{1} or is there a solution to put as many varargout as I want (varargout{2}, varargout{3} and not having structure to post-treat)?? It seems to me that the second option does not work.
2. Running the .m file results in getting an error and I think I know the reason. By using "delete(handles.figure1)", it seems that it also deletes the 's' structure which is my output. Does someone have an easy-to-implement way to delete the window but to continue running the main function with datas from the user??

Thanks for the time you'll spend reading and answering my post,

Bastien,

CODE:

function varargout = UI_JFC_Montant(varargin)
% UI_JFC_MONTANT MATLAB code for UI_JFC_Montant.fig
% UI_JFC_MONTANT, by itself, creates a new UI_JFC_MONTANT or raises the existing
% singleton*.
%
% H = UI_JFC_MONTANT returns the handle to a new UI_JFC_MONTANT or the handle to
% the existing singleton*.
%
% UI_JFC_MONTANT('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UI_JFC_MONTANT.M with the given input arguments.
%
% UI_JFC_MONTANT('Property','Value',...) creates a new UI_JFC_MONTANT or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before UI_JFC_Montant_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to UI_JFC_Montant_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
