pop up in address_book GUI demo with .mat file

hi all...

Could anyone show me how to use pop up menu in address_book gui demo rather than use push button menu??

thanks

Answer 1

[per isakson]

See GUI 28 and 33 in the FEX contribution 41 Complete GUI Examples

[Luhur]

thanks, but its different when using .mat file..

please be more specific..

[Walter Roberson]

Using a pop-up menu is not different when one is using a .mat file.

[Luhur]

would you mind explain it with the gui demo address_book.fig inside matlab??? cause my application similar with the demo and im not familiar with GUI..

thank you..

[Walter Roberson]

I do not have access to MATLAB today, so I cannot examine what they have done in that particular demo.

When you wrote "its different when using .mat file", did you mean that it is different when using GUIDE? The main difference when using GUIDE is that GUIDE likes to name the functions according to what kind of uicontrol is being used. The change at the MATLAB level between a pushbutton and a pop-up is very small, just set the uicontrol 'style' property to 'popup'

[Luhur]

okay, but please get back to me when you have access to matlab, i really need it, since it similar to my application. thanks

[Walter Roberson]

It would be much easier if you were to ask specific questions.

the push button replace with pop up menu. from the demo address_book.fig it used 2 push button previous and next. the script:

% ------------------------------------------------------------

% Callback for the Prev and Next buttons

% Pass a string argument (str) indicating which object was selected

% ------------------------------------------------------------

function Prev_Next_Callback(hObject, eventdata, handles, str)

% hObject handle to Prev_Next (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

% Get the index pointer and the addresses

index = handles.Index;

Addresses = handles.Addresses;

% Depending on whether Prev or Next was clicked change the display

switch str

case 'Prev'

% Decrease the index by one

i = index - 1;

% If the index is less then one then set it equal to the index of the

% last element in the Addresses array

if i < 1

i = length(Addresses);

end

case 'Next'

% Increase the index by one

i = index + 1;

% If the index is greater than the size of the array then point

% to the first item in the Addresses array

if i > length(Addresses)

i = 1;

end

end

% Get the appropriate data for the index in selected

Current_Name = Addresses(i).Name;

Current_Phone = Addresses(i).Phone;

set(handles.Contact_Name,'string',Current_Name)

set(handles.Contact_Phone,'string',Current_Phone)

% Update the index pointer to reflect the new index

handles.Index = i;

guidata(hObject,handles)

[Walter Roberson]

To adapt, use this routine as the callback for the popup menu, but do not pass any string in to it.

Instead, at the top,

menuval = get(hObject, 'Value');

menustrings = cellstr( get(hObject, 'String') );

str = menustrings{menuval};

And that's it for the code changes, provided that you set the popup menu to have entries 'Prev' and 'Next'

[Luhur]

you mean delete the whole script mine above and change it with yours?? can you be more specific as i a beginner for this.. if u dont have access to the matlab demo then i wrote the hole code in the next answer...

[Walter Roberson]

function Prev_Next_Callback(hObject, eventdata, handles) %CHANGE

% hObject handle to Prev_Next (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

menuval = get(hObject, 'Value'); %NEW

menustrings = cellstr( get(hObject, 'String') ); %NEW

str = menustrings{menuval}; %NEW

% Get the index pointer and the addresses

index = handles.Index;

Addresses = handles.Addresses;

% Depending on whether Prev or Next was clicked change the display

switch str

case 'Prev'

% Decrease the index by one

i = index - 1;

[etc to the rest of the routine]

And have this routine be the callback for your popup menu.

error walter... its sound:

??? Error using ==> address_book>Prev_Next_Callback

Too many input arguments.

Error in ==> gui_mainfcn at 96

feval(varargin{:});

Error in ==> address_book at 43

gui_mainfcn(gui_State, varargin{:});

Error in ==>

@(hObject,eventdata)address_book('Prev_Next_Callback',hObject,eventdata,guidata(hObject),'Next')

??? Error while evaluating uicontrol Callback

i already change the push button to pop up menu, with:

tag: Prev_Next

string: 1. Next

2. Prev

still error

any suggestion???

[Walter Roberson]

Use the property editor on that popup menu, and remove the comma and the 'Next' from the calling sequence.

[Luhur]

nice!! i miss that!! thanks walter!! :)

[Luhur]

walter.. i have some similar question,,

what if i have 2 pop up menu that related. each other, at first i have 1 structure. that contain 2 member

let say:

Car.truck.a=10

Car.truck.b=20

and

Car.jeep.c=7

Car.jeep.d=14

the 2 pop up menu are related, for example if i chose popup1 the string i jeep and truck, then after chose 1 ,let say i chose jeep, then the 2nd popup menu (popup2) revealed option c or d, then after i chose d, the value of text is 14.

how can i built this kind of case??

thank you

[Luhur]

Any thought Mr Walter?? i also post it in a new question for the detail..

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