MATLAB: GUI

guiMATLAB

I had created a simple GUI counting the number of cllicks and displaying it in an Edit Box. I noticed two problems :-

1. the gui doesn't work if we directly run the .fig file.. we have to run its .m file first. Any comments?

2. on closing some of my gui's, it generates these type of errors –

*??? Error using ==> feval Undefined function or method 'figure1_DeleteFcn' for input arguments of type 'struct'.

Error in ==> gui_mainfcn at 96 feval(varargin{:});

Error in ==> loadimg [dats my file name] at 43 gui_mainfcn(gui_State, varargin{:});

Error in ==> @(hObject,eventdata)loadimg('figure1_DeleteFcn',hObject,eventdata,guidata(hObject))

??? Error using ==> delete Error while evaluating figure DeleteFcn*

dont understand what this delete function is matlab talking about.. i just used a push button callback for counting and displaying the number of clicks.. no other function..

1. Correct. You must run the .m file. .fig files are not designed to be executable.

2. You renamed your .m file and .fig file outside of GUIDE. When you do that, GUIDE gets messed up. If you want a different name, you have to do it within GUIDE. Now you will need to check all the code in the .m file to look for references to figure1 and you will need to use the property inspector to go through all the object properties in your .fig file looking for references to figure1 . You will probably find it easier to delete your existing .m and .fig file and to rebuild it in GUIDE.

It appears that you renamed your files instead of working in GUIDE to rename items there.

It is possible to chase down all the resulting problems and fix them, but to be honest it is common that the fastest way to proceed is to create a new GUIDE project under the desired name.

First of all, you don't need anything in the callback for the radio buttons or uipanel unless you want to do something, like change a static text label or load a popup list or something like that. You don't need it to just set a and b like you did, since you can get those in the pushbutton callback just by calling get(). So clear out your uipanel1_SelectionChangeFcn() callback and then have just this as the pushbutton callback:

function pushbutton1_Callback(hObject, eventdata, handles)
  a = get(handles.radiobutton1,'value');
  b = get(handles.radiobutton2,'value');
  if a == 1
    uiwait(msgbox ('first button'));
  end
  if b == 1
    uiwait(msgbox('second button'));
  end
end
