<section id="signals2.examples.tutorial.hello_world_slot">
<title>hello_world_slot</title>
<para>
This example is a basic example of connecting a slot to a signal
and then invoking the signal.

<section id="signals2.examples.tutorial.hello_world_multi_slot">
<title>hello_world_multi_slot</title>
<para>
This example extends the hello_world_slot example slightly by connecting more than one
slot to the signal before invoking it.

<title>ordering_slots</title>
<para>
This example extends the hello_world_multi_slot example slightly by
using slot groups to specify
the order slots should be invoked.

<section id="signals2.examples.tutorial.slot_arguments">
<title>slot_arguments</title>
<para>
The slot_arguments program shows how to pass arguments from a signal invocation to slots.

<section id="signals2.examples.tutorial.signal_return_value">
<title>signal_return_value</title>
<para>
This example shows how to return a value from slots to the signal invocation.
It uses the default <classname>optional_last_value</classname> combiner.

<section id="signals2.examples.tutorial.custom_combiners">
<title>custom_combiners</title>
<para>
This example shows more returning of values from slots to the signal invocation.
This time, custom combiners are defined and used.

<section id="signals2.examples.tutorial.disconnect_and_block">
<title>disconnect_and_block</title>
<para>
This example demonstrates various means of manually disconnecting slots, as well as temporarily
blocking them via <classname>shared_connection_block</classname>.

<section id="signals2.examples.tutorial.passing_slots">
<title>passing_slots</title>
<para>
This example demonstrates the passing of slot functions to a private signal
through a non-template interface.

<section id="signals2.examples.tutorial.extended_slot">
<title>extended_slot</title>
<para>
This example demonstrates connecting an extended slot to a signal. An extended slot
accepts a reference to its invoking signal-slot connection as an additional argument,
permitting the slot to temporarily block or permanently disconnect itself.

<title>doc_view</title>
<para>
This is the document-view example program which is described in the
<link linkend="signals2.tutorial.document-view">tutorial</link>. It shows
usage of a signal and slots to implement two different views of
a text document.
