<p>Qt4 And Hildon Home Widget Interaction</p> <p><b>New page</b></p><div>The code in this wiki page is taken from the [http://maemo.org/packages/view/dlh/ dlh application] and the [http://maemo.org/packages/view/dlh-widget/ dlh widget]. Since it is FOSS, the source code is available for anyone to adapt freely.<br /> <br /> == Service ==<br /> The com.nokia.dlh.service file defines the D-Bus service provided by the Qt4 application:<br /> <br /> [D-BUS Service]<br /> Name=com.nokia.dlh<br /> Exec=/opt/maemo/usr/bin/dlh<br /> <br /> There&#039;s a reference to this service in the dlh.desktop file too:<br /> X-Osso-Service=com.nokia.dlh<br /> <br /> == Application ==<br /> <br /> In the class definition of the objects which will interact with the home widget you need the Q_CLASSINFO macro:<br /> <br /> class Widget : public QWidget<br /> {<br /> Q_OBJECT<br /> Q_CLASSINFO(&quot;D-Bus Interface&quot;, &quot;com.nokia.dlh&quot;)<br /> [...]<br /> <br /> The slots have the same name of the D-Bus messages; Q_NOREPLY mark a method to be called and not wait for it to finish processing before returning (see Qt docs):<br /> <br /> Q_NOREPLY void CallStartDialog();<br /> <br /> The class constructor contains the service and the object registration:<br /> <br /> QDBusConnection::sessionBus().registerService(&quot;com.nokia.dlh&quot;);<br /> QDBusConnection::sessionBus().registerObject(&quot;/com/nokia/dlh&quot;,this, QDBusConnection::ExportAllContents);<br /> <br /> == Home Widget ==<br /> <br /> Some defines:<br /> <br /> #define DLH_SERVICE &quot;com.nokia.dlh&quot;<br /> #define DLH_OBJECT &quot;/com/nokia/dlh&quot;<br /> #define DLH_IFACE &quot;com.nokia.dlh&quot;<br /> <br /> In the init function you have to initialize the osso library (see [http://maemo.org/api_refs/5.0/5.0-final/libosso/ libosso docs]):<br /> <br /> osso_context = osso_initialize (&quot;com.nokia.dlh-widget&quot;, &quot;0.1&quot;, 0, NULL);<br /> <br /> When you want to execute the Qt object&#039;s slot &#039;&#039;CallStartDialog&#039;&#039; from the home widget you will use the following instruction:<br /> <br /> osso_rpc_run(osso_context,<br /> DLH_SERVICE,<br /> DLH_OBJECT,<br /> DLH_IFACE,<br /> &quot;CallStartDialog&quot;, NULL, DBUS_TYPE_INVALID);<br /> <br /> That&#039;s all!</div>
