Problem Error when trying to appear / disappear a text edit based on some radio buttons within a button group

I'm making a GUI where basically I have 3 radio button within a button group and out I have 3 edit text. Depending on the selection of a radio edit button disappears for a particular text, entry in the other 2 values and operate with them. Up there in the first run and all good, the problem is that after that first calculate the change in radio button and get rid of a text edit and re-make it appear that he was invisible and will not let me get the following error: ??? Error using ==> set Invalid handle object.

Error in ==> Direct_E>uipanel1_SelectionChangeFcn at 102
    set(handles.p1,'Visible','off');

Error in ==> gui_mainfcn at 96

??? Error while evaluating uicontrol Callback

This is my source code:

function varargout = Direct_E(varargin)

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

Does anyone know why this happens? Thank you very much, Luis

Please, Can anyone help me? It is very important. Thanks.

Answer 2

[Andy Dixon]

It's a bit difficult to see what's going on without the .fig file created by GUIDE. However, I've put together a basic function which shows the behaviour you're trying to get, I think.

Hopefully the code is easy enough to understand and will give you an idea why yours is failing.

Andy

% START CODE
  function test_ToggleControls
  % Create figure
  h = figure('Visible','on');
  % Add two radio buttons
  uicontrol('Parent',h, ...
    'Callback',@cb_radioBtn1, ...
      'Position',[50 100 100 18], ...
      'String','Button 1', ...
      'Style','RadioButton', ...
      'Tag','radioBtn1');
  uicontrol('Parent',h, ...
    'Callback',@cb_radioBtn2, ...
      'Position',[50 80 100 18], ...
      'String','Button 2', ...
      'Style','RadioButton', ...
      'Tag','radioBtn2');
  % Add two edit boxes
  uicontrol('Parent',h, ...
      'Position',[155 100 100 18], ...
      'Style','Edit', ...
      'Tag','edit1', ...
      'Visible','off');
  uicontrol('Parent',h, ...
      'Position',[155 80 100 18], ...
      'Style','Edit', ...
      'Tag','edit2', ...
      'Visible','off');

    % Callback functions for radio button 1
    function cb_radioBtn1(h, eventData)
    handles = guihandles(gcbf);
    set([handles.radioBtn1 handles.radioBtn2],'Value',0)
    set(h,'Value',1)
    set([handles.edit1 handles.edit2],'Visible','off')
    set(handles.edit1,'Visible','on')

    % Callback functions for radio button 2
    function cb_radioBtn2(h, eventData)
    handles = guihandles(gcbf);
    set([handles.radioBtn1 handles.radioBtn2],'Value',0)
    set(h,'Value',1)
    set([handles.edit1 handles.edit2],'Visible','off')
    set(handles.edit2,'Visible','on')
  % END CODE

Answer 3

[Luis Manuel]

Thanks for your answer.The problem is when the program does his first calculation on function "REPRESENTAR_Callback", I don´t understand why it is happens. I have reviewed it 100 times but I don´t understand. Help me please. Thank you.

[Andy Dixon]

Luis,

In REPRESENTAR_Callback you seem to using uicontrol handle values within your calculations. This may not be the cause of your problem, but it seems strange.

For example: if seleccion = 1, you use the uicontrol handles b1 and p1 to calculate termino_Fresnel

I haven't managed to replicate your error. Can you post the .fig file that goes with your code somewhere?

Andy

[Luis Manuel]

What is your e-mail? My email is: [e-mail]. Please, send me a message and I can send you my source code and my figure. Thank you.

Answer 5

[Luis Manuel]

I have upload my .fig and .m files. This is the link:

Thank you,

Luis

[Andy Dixon]

I'm afraid I can't do anything with your code as it causes a segmentation violation in MATLAB. I'm only using R2006b and I assume your code was created in a later version. In particular, the form of the uicontrol callbacks has changed.

Sorry about that.
