Setappdata et Getappdata

**avia767** · 22/06/2014, 01h47

Bonjour,
je souhaite créer sous guide une GUI avec ;
1- Des variables initialisés des le lancement
2- Variable globales qui s'affiche sur le workspace des le lancement
3- Variables que je peux modifier a partir de ma GUI et les voir sous le workspace sous la forme matricielle, toutes mes valeurs modifié sont enregistrés dans mes variable.
4-enregistrer les valeurs de mes variables

pour cela l'utilisation de appdata avec les setappdata et getappdata est recommande selon ma lecture.

voici le code que j'ai commencé mais je n'arrive pas avec appdata.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

function varargout = test111(varargin)
% TEST111 MATLAB code for test111.fig
%      TEST111, by itself, creates a new TEST111 or raises the existing
%      singleton*.
%
%      H = TEST111 returns the handle to a new TEST111 or the handle to
%      the existing singleton*.
%
%      TEST111('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TEST111.M with the given input arguments.
%
%      TEST111('Property','Value',...) creates a new TEST111 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before test111_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to test111_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

Pour stocker les valeurs dans le Workspace de MATLAB, tu peux soit utiliser assignin à la fin du CallBack du bouton :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

assignin('base', 'a', handles.a)

Soit récupérer les valeurs directement depuis MATLAB (tant que l'objet Figure n'est pas détruit) :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part
