Detailed Description

Slots are type-safe representations of callback methods and functions.

A Slot can be constructed from any function, regardless of whether it is a global function, a member method, static, or virtual.

Use the SigC::slot() template function to get a SigC::Slot, like so:

 SigC::Slot1<void, int> slot = SigC::slot(someobj, &SomeClass::somemethod);

or

 m_Button.signal_clicked().connect( SigC::slot(*this, &MyWindow::on_button_clicked) );

The compiler will complain if SomeClass::somemethod has the wrong signature.

You can also pass slots as method parameters where you might normally pass a function pointer.
