Hi I'm trying to create a GUI that use several algorithms and functions and, some of the things that I am trying to do is to call GUIs with other GUIs but I don't want to create a GUI that callsback another one but rather I want one that can integrate the three GUIs in one, kind of the tab systems in Chromme or another explorer.
Thanks

According to this post, there is tab-panel capability in R2011a. I don't have R2011a so don't have hands-on experience. But even if you don't have tab-panel, there is also a practical approach to help you organize your GUI elements.

Here is the link from TMW. It seems to be still a "undocumented feature" in R2011a. http://www.mathworks.com/help/techdoc/uitools_csh/error_pages/bslcn87.html

Sorry to comment after I accepted the answer but, I'm having a problem with the implementation of the visible property using a list box to choose between 3 options that should control the visible property of the elements in my GUI. The problem is that when I change between one selection in the list box to another, it doesn't change the visible property of the elements, actually it doesn't do anything. But if I run the same code for manipulating the visible property in GUI_OpeningFcn it works perfect.
Can you help me with that? maybe I'm missing something and I can't find it.
Thanks

I put all my elements that are corresponding to that listbox option inside a panel. I only need to set the visibility of the panel to be off to hide all the elements inside the panel. Remember, if you have multiple options, at any time, you want to turn on one panel and turn off one panel. So you need to have a way to remember the panel that was previous on. I use 'UserData' for that. The code is pretty simple. I don't have a good idea what is your problem. It sounds like not related to this particular technique.
function OptionList_Callback(hObject, eventdata, handles) %#ok
% hObject handle to OptionList (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: contents = get(hObject,'String') returns OptionList contents as cell array
% contents{get(hObject,'Value')} returns selected item from OptionList
contents = get(hObject,'String');
CurrentSelection=contents{get(hObject,'Value')};
PreviousSelection=get(hObject,'UserData');
set(hObject,'UserData',CurrentSelection);
set(handles.([PreviousSelection,'Panel']),'Visible','Off');
set(handles.([CurrentSelection,'Panel']),'Visible','On');

In the code above, assume your listbox has option for 'x','y' and 'z', the panel name in the GUI is purposely named as xPanel, yPanel and zPanel to make it work.
When you design your GUI using GUIDE, you can make xPanel visible and put it at the desired position. Set the 'Visible' property of yPanel and zPanel to be 'Off' and put them at the outer of your GUI layout. Once your GUI design is done, you can re-size your GUI window to leave yPanel and zPanel at outside. In your GUI's OpeningFcn callback, you need to read in the postion of xPanel and assign them to the position of yPanel and zPanel. yPanel and zPanel are still invisible so won't cause problem. This way, when you choose different option from the listbox, the view of the different panel is seamlessly transitioned.
