MATLAB: Select one of two images displayed on a GUI

Question

Hey guys, im experiencing some problems. I have a GUI where I display my two images so the user can easily choose one of them through two buttons.

function removedBackgroundSelectorView_OpeningFcn(hObject, eventdata, handles, varargin)
    axes(handles.axes1);
    imshow(varargin{1}{1});
    axes(handles.axes2);
    imshow(varargin{1}{2});
    handles.output = hObject;
    guidata(hObject, handles);

The callbacks:

function button1_Callback(hObject, eventdata, handles)
    handles.output = handles.axes1;
    uiresume;
function button2_Callback(hObject, eventdata, handles)
    handles.output = handles.axes2;
    uiresume;

And the output function

function varargout = removedBackgroundSelectorView_OutputFcn(hObject, eventdata, handles) 
    uiwait;
    varargout{1} = getimage(handles.output);

So, there is my problem, it does not matter wich button I press, I always get the image from axes2. I tried really hard to solve it by myself but had no results.

Thanks

You need to call guidata() otherwise handles is not updated permanently. You made a new output field but it's basically thrown away when you exit the push button callback.
