Matlab: Changer couleur selon le choix d'un listBox

[invite19a844bd]

Salut,

Je veux changer la couleur d'un bouton "Pass" selon le choix du ListBox comme montre le code suivant:

function list_VIN_Callback(hObject, eventdata, handles) 
if strcmp(get(handles.list_VIN,'String'), '...............< Aucun >.............') 
  
    set(handles.Pass, 'BackgroundColor','red'); 
   
   else 
    set(handles.Pass, 'BackgroundColor','green'); 
    
end;

Quand je fais un choix VIN1, VIN2 ou VIN3 la couleur du bouton "Pass" devient verte mais quand je fais le choix "........<Aucun>........." la couleur ne change pas ou reste verte? Pourriez vous m'aider svp?

Merci

Bonjour,

Peux-tu poster ici le code complet, pour qu'on puisse l'executer et voir ce qui advient ?

Sinon, met-toi en mode débug et observe l'état des variables à chaque ligne, pour voir ce qui est conforme ou non aux attentes.

Tu programme pour quelle version de matlab ?

function varargout = ListBOx(varargin)
% LISTBOX MATLAB code for ListBOx.fig
% LISTBOX, by itself, creates a new LISTBOX or raises the existing
% singleton*.
%
% H = LISTBOX returns the handle to a new LISTBOX or the handle to
% the existing singleton*.
%
% LISTBOX('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in LISTBOX.M with the given input arguments.
%
% LISTBOX('Property','Value',...) creates a new LISTBOX or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before ListBOx_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to ListBOx_OpeningFcn via varargin.

Bonjour,

Je t'invite à te mettre en mode débug, en particulier à partir de la ligne :
>> if strcmp(get(handles.list_VIN,'S tring'), '...............< Aucun >.............')
et à observer l'état des variables à chaque ligne, pour voir ce qui est conforme ou non aux attentes.

Car le code que tu as envoyé n'est pas simulable en l'état.

Edit : je déplace la discussion dans un forum plus adapté.
