|
|
libunique lets you send messages with commands to a running
|
|
instance using unique_app_send_message(). The commands can be either
|
|
predefined or custom. Some of the predefined libunique commands have
|
|
equivalents in GApplication. Instead of sending the UNIQUE_ACTIVATE
|
|
command, call <code class="function">g_application_activate()</code>, instead of sending the
|
|
UNIQUE_OPEN command, call <code class="function">g_application_open()</code>. The
|
|
UNIQUE_NEW and UNIQUE_CLOSE and user-defined commands don't
|
|
have direct replacement at this time.
|
|
</p>
|
|
<p>
|
|
As a replacement for custom commands, GApplication implements the
|
|
<span class="type">GActionGroup</span> interface and lets you add a group of actions with
|
|
<code class="function">g_application_set_action_group()</code>. The actions can then be invoked,
|
|
either by using the D-Bus interface for <span class="type">GAction</span> directly, or by
|
|
calling <code class="function">g_action_group_activate_action()</code> from another instance of
|
|
the GApplication. The <span class="type">GApplication</span> documentation contains an
|
|
example for using GApplication with actions.
|
|
</p>
|
|
<p>
|
|
For more complex needs, GApplication supports passing entire
|
|
commandlines to the running instance.
