II.2.Exemple :
le GUIDE génère deux fichiers :
· un fichier .fig (non éditable) contenant les
objets graphiques Figure, Axes et Pushbutton ;
· un fichier .m contenant le code du fonctionnement de
l'interface graphique.
Il reste ensuite à ajouter au fichier .m, le code
correspondant à l'action à effectuer lors du clique sur le
bouton, à savoir le changement de couleur de l'objet Axes.
Dans notre cas, il faut ajouter la ligne suivante :
set(handles.axes1, 'color', rand(1,3))
Elle se place à la fin du code dans la fonction
pushbutton1_Callback
Le contenu du fichier .m créé par le GUIDE devient
donc :
function varargout = exemple_guide(varargin)
% EXEMPLE_GUIDE MATLAB code for exemple_guide.fig
% EXEMPLE_GUIDE, by itself, creates a new EXEMPLE_GUIDE or raises
the existing % singleton*.
%
% H = EXEMPLE_GUIDE returns the handle to a new EXEMPLE_GUIDE or
the handle
to

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