[gtkmm] Gtk::Window

[Alexander Bussman <buxman telia com>]

Hi!
I wonder if it's a way to lock the application until a newly created 
window is closed.
I need to do that because I want to grab a string from that window (that 
the user writes).

something like this I mean:
...
mywindow.show();
wait_until_mywindow_is_closed();
std::string data = mywindow.getData();
...

I can't figure out a good way to do this.... anyone?
