Boost gurus,
I am using boost::bind in combination with boost::signals for a GUI
toolkit. The signals return bool for convenience, but it is often
desireable to bind a void function and connect it to a signal. Is there
a convenient way to assign a return value for a void function.
As an example:
-----------------------------------------------------------------
struct panel
{
void print() { std::cout << "print" << std::endl; }
}
struct widget
{
boost::signal<bool ()> on_event;
}
panel p;
widget w;
// is there some way to do something like this?
w.on_event.connect(boost::bind_return(panel::print, &p, true));
-----------------------------------------------------------------
Many thanks in advance,
Darren Hart
