Accessing variables between pushbuttons in MATLAB GUI

Hi,

I have two pushbuttons in MATLAB GUI. When I press one pushbutton it executes certain set of codes including function call. The variables returned by this function call need to be sent to the function call which executes when other push button is pressed. But, I get the following error:

Error using hg.uicontrol/get The name 'MySet' is not an accessible property for an instance of class 'uicontrol'.

Error in test3>pushbutton_forfind_Callback (line 481) MySet = get(handles.pushbutton1,'MySet');

Error in gui_mainfcn (line 96) feval(varargin{:});

Error in test3 (line 42) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)test3('pushbutton_forfind_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

MySet is the variable returned by function called by first pushbutton which needs to be passed to another function call in second pushbutton. How can I resolve this error?

Thanks.

How are you setting 'MySet' to be a field of handles? You need to use either setappdata & getappdata or guidata.

I m doing this in function call of pushbutton 1:

handles.MySet = MySet;
guidata(hObject, handles);

Then retrieving in another pushbutton2 by:

MySet = get(handles.pushbutton1,'MySet');

Just

MySet = handles.MySet;

Thanks a lot for pointing out this. I am so happy that it worked.
