<title>The &k3b; &DCOP; Interface</title>
|
||
|
|
<para>&k3b; features, like many other &kde; applications as well, a
|
||
|
|
&DCOP; interface which makes it possible to control a part of it's
|
||
|
|
functionality from ⪚ a shellscript.</para>
|
||
|
|
<para>To use these &DCOP; functions you can either use the
|
||
|
|
<command>dcop</command> commandline program or the more convenient
|
||
|
|
<application>Kdcop</application> application. Both provide the same
|
||
|
|
functionality so it's mostly a matter of taste and context of usage when
|
||
|
|
deciding which way to choose.</para>
|
||
|
|
<para>This chapter assumes that you're using the <command>dcop</command>
|
||
|
|
commandline program. To access &k3b;'s &DCOP; functions, make sure that
|
||
|
|
&k3b; is started and then enter something like this at a console:
|
||
|
|
<screen>
|
||
|
|
<prompt>#</prompt> <command>dcop</command> <option>k3b</option> <option>K3bInterface</option> <replaceable>[function]</replaceable>
|
||
|
|
</screen>
|
||
|
|
</para>
|
||
|
|
|
||
|
|
<para>Besides the generic &DCOP; functions available to all &kde;
|
||
|
|
applications, &k3b;'s DCOP interface mainly consists of two parts as described below.</para>
|
||
|
|
|

|
|
<sect1>
|
||
|
|
<title>The default K3bInterface</title>
|
||
|
|
|
||
|
|
<para>The default K3b DCOP interface provides functionality like copyCD, formatDVD, and methods for creating new projects.</para>

|
|
|

|
<para>As result from one of the createXXXProject methods one gets a DCOP reference to the newly created project:
|
||
|
|
|
||
|
|
<programlisting>DCOPRef(k3b,K3bProject-0)</programlisting>
|
||
|
|
|
||
|
|
Alternatively you may create a project using the command line:
|
||
|
|
|
||
|
|
<screen>
|
||
|
|
<prompt>#</prompt> <command>k3b</command> <replaceable>--audiocd</replaceable>
|
||
|
|
</screen>
|
||
|
|
|
||
|
|
and then retrieve a reference to this project with
|
||
|
|
|
||
|
|
<screen>
|
||
|
|
<prompt>#</prompt> <command>dcop</command> <option>k3b</option> <option>K3bInterface</option> <replaceable>currentProject</replaceable>
|
||
|
|
</screen>
|
||
|
|
|
||
|
|
Using this reference it is possible to manipulate the project using the <link linkend="k3bprojectinterface">K3bProjectInterface</link>.</para>

<para>K3b offers the K3bProjectInterface as listed above or the more powerful K3bDataProjectInterface which only applies to data projects (CD and DVD):
|
||
|
|
|
||
|
|
<programlisting>
|
||
|
|
void createFolder(QString name)
|
||
|
|
void createFolder(QString name,QString parent)
|

void addUrl(KURL url,QString parent)
|
||
|

void addUrls(KURL::List urls,QString parent)
|
||
|
|
void removeItem(QString path)
|
||
|
|
void renameItem(QString path,QString newName)
|
||
|
|
void setVolumeID(QString id)
|
||
|
|
</programlisting>
|
||
|
|
</para>
|
||
|
|
|
||
|
|
<para>Using this it is possible to fill a data project with files and folders from a script.
|
||
|
|
The following script for example creates a new data project, adds several folders to the project, and adds files to the newly created folders:
|
||
|
|
|
||
|
|
<programlisting>
|
||
|
|
#!/bin/bash
|
||
|
|
PROJECT=$(dcop k3b K3bInterface createDataCDProject)
|
||
|
|
dcop $PROJECT createFolder test
|
||
|
|
dcop $PROJECT createFolder foo
|
||
|
|
dcop $PROJECT createFolder bar /foo
|
||
|
|
dcop $PROJECT addUrl /home/trueg/somefile.txt /foo/bar
|
||
|

</programlisting>
