gtkmm, how can I make my program waiting the clicked signal from a button?

Question

I want to make my program waiting until a button is clicked.

The problems are,

• I can't use trhead
• I can't use a dialog or another window
• I cant't use a function like Glib::usleep() because it makes the interfaces insensitive.

I don't found any strategy to solve that problem.

Ok, I found a solution:

// computation going on
while( Gtk::Main::events_pending() )
Gtk::Main::iteration();
// computation continued
