hay everyone ...
i'm trying to solve the problem caused when the user click the close button of the window created using CL_DisplayWindow and nothing happened.

i have tried to handle the the signal emitted using this line:

window.sig_window_close().connect( closeButtonClicked );
where closeButtonClicked is a custom defined function that close the application and release resources.

but the main problem is that solution doesn't work for me.
any suggestion?
