Guide not generating callbacks

Hi,

I have a GUI that is made with GUIDE. The GUI works but when I have to modify the GUI with an extra button or something, I click View>Callbacks on the new button and GUIDE does not automatically generate new callback function for it.

Does anyone know the cause for this?

Have you tryed saving the new gui? In my experiance the new callbacks are only made after you pressed save.

I have tried saving the new modifications, if that is what you mean. I already have an existing GUI where GUIDE used to automatically generate callbacks. Now when I make add some modifications, it does not generate the new callbacks, even after saving.

I will describe how I add a new button;

1. In matlab press GUIDE
2. Open Existing GUI
3. C:\MyGui
4. Now add a Push Button

If I use your method ViewCallbacks>callback in my code there appears a new function named: pushbutton2_Callback(hObject, eventdata, handles). Somthimes it is named "Newfunction"

If that does not work you can try my method:

1. Right click the new pushbutton and select property inspector.
2. Go to "Tag" you can find this on the left side 7th from the bottom
3. On the right side of "Tag" you see the text "Push Button"
4. Replace this text with w/e you want your function to be named for example: NewPushbutton
5. now close the inspector
6. On your guiscreen pres the save button

if it is correct you will now get your new function code looking like:

% --- Executes on button press in NewPushbuttonTag.
function NewPushbuttonTag_Callback(hObject, eventdata, handles)
% hObject    handle to NewPushbuttonTag (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

Maybe this different method will help

Hi Nick,

Unfortunately that didn't work either. Sighhh

Hello Horace,

Well the last thing I can think of than is to save the entire gui with new button with a different file name. And coppy paste the code you already wrote to the new file.

Hi Horace,

If you navigate to Tools->GUI Options, is "generate callback function prototypes" enabled?

[Horace]

YES! That was the issue! Thanks!

Great; One success for the week already!

Please accept this answer.

Another dog!? I didn't know you had two.

[Sean de Wolski]

Yup!

My wife (whose parents have sled dogs) wants a third since we're trying to get into ski-jouring. However, the snow gods aren't cooperating.

So great!

It is effective for me!
