Call method from another GUI

I have two GUIs, GUI1 and GUI2. Before I close GUI2 completely, I want to call a function from GUI1.

% In GUI2
gui1 = findobj('Tag', 'GUI1');
gui1.callThisBeforeClosingFcn();
close(handles.GUI2);

I get an error when trying to call the GUI1 function - "No appropriate method, propery, or field 'callThisBeforeClosingFcn' for class matlab.ui.Figure."

What is the correct way to call that function?

I cannot guess, what "gui1.callThisBeforeClosingFcn()" should be. Perhaops you want to call a function before closing the figure autoamtically? But what might "from another GUI" mean then...

figure('CloseRequestFcn', @callThisBeforeClosingFcn, ...
       'DeleteFcn', @callThisBeforeClosingFcn);

and your function:

function callThisBeforeClosingFcn(FigH, EventData)
handles = guidata(FigH);
... do whatever you want
figure('CloseRequestFcn', [], ...
       'DeleteFcn', []);
delete(figure);

Now simply close or delete the figure, or close it using the "x" in the window border and the specified function is called automatically.

The function I want to call is from another GUI's m file. I have GUI2.m, from which I need to call the function callThisBeforeClosingFcn that is located in GUI1.m. Does this help clarify?

In other words - I want to call a method from another m file. How can I do that?
