Need help with a school treeplot "homework".

Build a GUI application for the syntaxes:

treeplot (p)
treeplot (p, nodeSpec, edgeSpec)

It is required in the graphical interface to find:

· A menu called 'Sintaxe' and 2 submenus that allows to select the syntax of the desired function

· An edit box for reading p

· Graphical objects to read input arguments nodeSpec, edgeSpec

· A button called 'Rezultat' that, when enabled, displays graphical representations of functions on an axis object.

So far i got this:

function varargout = untitled(varargin)
% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @untitled_OpeningFcn, ...
                   'gui_OutputFcn',  @untitled_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end
% End initialization code - DO NOT EDIT

function untitled_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);

function varargout = untitled_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;

function sintaxe_Callback(hObject, eventdata, handles)

function functia1_Callback(hObject, eventdata, handles)
treeplot([0 1 1]);

function functia2_Callback(hObject, eventdata, handles)
treeplot([0 1 1 1]);

uicontrol should be helpful here. Those callbacks don't do anything by themselves. The code you posted looks like a cleaned up version of the default output of GUIDE. GUIDE also has an option to generate the code for the .fig.

Managed to get this so far, however i wish to clean up a bit the code and also to rename the Menu from treeplot to Sintaxe and i can't find this option :( Any thoughts? Thanks a lot!

Why are you using a global, instead of saving it to a field in your guidata? And what do you mean with renaming the menu? Do you want to rename the function?

%replace
global aux;
aux = 0;
%with
handles.aux=0;
guidata(hObject,handles)

%and in pushbutton1_Callback, replace
global aux;
%with
aux=handles.aux;

Thanks Rik. When i run this, i get a fig file and i am able to run the submenus treeplot (p) and treeplot (p, nodeSpec, edgeSpec), but the main menu is called treeplot instead of Sintaxe like it was requested in the exercise content. Anyway thanks a lot for clearing out the global aux.
