-<a name="GActionGroup.description"></a><h2>Description</h2>
-<p>
-<a class="link" href="GActionGroup.html" title="GActionGroup"><span class="type">GActionGroup</span></a> represents a group of actions. Actions can be used to
-expose functionality in a structured way, either from one part of a
-program to another, or to the outside world. Action groups are often
-used together with a <a class="link" href="GMenuModel.html" title="GMenuModel"><span class="type">GMenuModel</span></a> that provides additional
-representation data for displaying the actions to the user, e.g. in
-a menu.
-</p>
-<p>
-The main way to interact with the actions in a GActionGroup is to
-activate them with <a class="link" href="GActionGroup.html#g-action-group-activate-action" title="g_action_group_activate_action ()"><code class="function">g_action_group_activate_action()</code></a>. Activating an
-action may require a <a href="./../glib/glib/glib-GVariant.html#GVariant"><span class="type">GVariant</span></a> parameter. The required type of the
-parameter can be inquired with <a class="link" href="GActionGroup.html#g-action-group-get-action-parameter-type" title="g_action_group_get_action_parameter_type ()"><code class="function">g_action_group_get_action_parameter_type()</code></a>.
-Actions may be disabled, see <a class="link" href="GActionGroup.html#g-action-group-get-action-enabled" title="g_action_group_get_action_enabled ()"><code class="function">g_action_group_get_action_enabled()</code></a>.
-Activating a disabled action has no effect.
-</p>
-<p>
-Actions may optionally have a state in the form of a <a href="./../glib/glib/glib-GVariant.html#GVariant"><span class="type">GVariant</span></a>. The
-current state of an action can be inquired with
-<a class="link" href="GActionGroup.html#g-action-group-get-action-state" title="g_action_group_get_action_state ()"><code class="function">g_action_group_get_action_state()</code></a>. Activating a stateful action may
-change its state, but it is also possible to set the state by calling
-<a class="link" href="GActionGroup.html#g-action-group-change-action-state" title="g_action_group_change_action_state ()"><code class="function">g_action_group_change_action_state()</code></a>.
-</p>
-<p>
-As typical example, consider a text editing application which has an
-option to change the current font to 'bold'. A good way to represent
-this would be a stateful action, with a boolean state. Activating the
-action would toggle the state.
-</p>
-<p>
-Each action in the group has a unique name (which is a string). All
-method calls, except <a class="link" href="GActionGroup.html#g-action-group-list-actions" title="g_action_group_list_actions ()"><code class="function">g_action_group_list_actions()</code></a> take the name of
-an action as an argument.
-</p>
-<p>
-The <a class="link" href="GActionGroup.html" title="GActionGroup"><span class="type">GActionGroup</span></a> API is meant to be the 'public' API to the action
-group. The calls here are exactly the interaction that 'external
-forces' (eg: UI, incoming D-Bus messages, etc.) are supposed to have
-with actions. 'Internal' APIs (ie: ones meant only to be accessed by
-the action group implementation) are found on subclasses. This is
-why you will find - for example - <a class="link" href="GActionGroup.html#g-action-group-get-action-enabled" title="g_action_group_get_action_enabled ()"><code class="function">g_action_group_get_action_enabled()</code></a>
-but not an equivalent <code class="function"><code class="function">set()</code></code> call.
-</p>
-<p>
-Signals are emitted on the action group in response to state changes
-on individual actions.
-</p>
-<p>
-Implementations of <a class="link" href="GActionGroup.html" title="GActionGroup"><span class="type">GActionGroup</span></a> should provide implementations for
-the virtual functions <a class="link" href="GActionGroup.html#g-action-group-list-actions" title="g_action_group_list_actions ()"><code class="function">g_action_group_list_actions()</code></a> and
-<a class="link" href="GActionGroup.html#g-action-group-query-action" title="g_action_group_query_action ()"><code class="function">g_action_group_query_action()</code></a>. The other virtual functions should
-not be implemented - their "wrappers" are actually implemented with
-calls to <a class="link" href="GActionGroup.html#g-action-group-query-action" title="g_action_group_query_action ()"><code class="function">g_action_group_query_action()</code></a>.

-</p>
-<p>
-The interface provides a default implementation of this function that

-therefore, must override either this function or all of the others.
