[gtkmm] window destroy event

[Erwan Ancel <eancel amadeus net>]

Hi,

I have troubles while handling the destroy event of a window: I would like
to avoid destroying the window in some cases.
I connect a method to the event: this works fine:
myWindow.signal_delete_event().connect(SigC::slot(*this,
&MyWindow::closeCrossClicked));

But In this method MyWindow::closeCrossClicked, how can I cancel the window
destruction ?
