Function of the toolbar-cross

Hey everyone, does anyone know how/where to edit a GUI's closing function (if there even is one)? I'm not talking about commands like close but the X-button in the top right corner of the window. By hitting the X-button I want my GUI to call a certain function. Any ideas?

This does execute the CloseRequestFcn of the figure:

function exampleCloseReq

figure('CloseRequestFcn',@closeme)

function closeme(src,evt);

disp('I''m closing');
delete(src)

Save this as exampleCloseReq.m
