Cool. You've demonstrated Ruby Blocks in C++.
How about creating a simple class:
class bend {
widget* _w;
public:
bend( widget* w ) : _w( w ) { _w->begin(); };
~bend() { _w->end(); };
}; // end bend
...;
widget* s = new widget( ... );
...;
{
bend b( s );
new control1( ... );
new control2( ... );
new control3( ... );
};
...;
