Function related to Event Listener not found

Hi all,

I have a simulink model (.slx file) and a gui (.mlapp file created with App Designer). They are located into the same folder. I added the following code to the StartFcn of the simulink model

h = add_exec_event_listener('blockDiagram/mySubSys', 'PostOutputs', @gui.myFunc);

and I defined a function, called myFunc, into the gui file, in this way

methods (Access = public)

          function myFunc(block, ~)
              % code
          end

end

Unfortunately, when I run the model, the Command Window displays the following error

Undefined function 'gui.myFunc' for input arguments of type 'Simulink.RunTimeBlock'.

So, how can I solve this problem ?

Thank you for reading.

Perhaps

h = add_exec_event_listener('blockDiagram/mySubSys', 'PostOutputs', @(varargin) gui.myFunc);

or

h = add_exec_event_listener('blockDiagram/mySubSys', 'PostOutputs', @(varargin) myFunc(gui));

Hi, thank you for your reply. When I use the first expression, MATLAB says me

 The class gui has no Constant property or Static method named 'myFunc'.
 Error in gui>@(varargin)gui.myFunc

When I use the second expression, MATLAB opens several windows of my GUI, but it doesn't print any error message.

However, App Designer suggests that I have to "use app as the first argument for myFunc". But the result is the same.
