Probably in class B connect to signal emitted by class A, in which you
change a label. In rough pseudocode that would look like this:
class A
{
public:
signal_something();
};
class B
{
Label m_l;
A m_a;
public:
B();
something_handler();
};
B::B()
{
m_a.signal_something().connect(*this, &something_handler());
}
B::something_handler()
{
m_l.set_text("blabla");
}
