MATLAB: SelectionChangeFcn not receiving handles

Question

I'm trying to have a gui (made using GUIDE) run some code when the selection of a radio button is changed.

The radio buttons are in a uipanel, I have added the following to the OpeningFcn:

set(handles.uipanel1,'SelectionChangeFcn',@uipanel1_SelectionChangeFcn);

and defined the SelectionChangeFcn as:

function uipanel1_SelectionChangeFcn(hObject, eventdata, handles)
who

However, the output of 'who' is:

Your variables are:
eventdata  hObject

Is there a way to pass the handles structure to it too? I have a function that updates the gui, based on the contents of handles which I want to call from the SelectionChangeFcn.

Cheers

Answer 1

set(handles.uipanel1,'SelectionChangeFcn',...{@uipanel1_SelectionChangeFcn,handles});
