38 /* Corresponding XML definition code:
39  * ----------------------------------
40  *
41  * The following lines from the xml_gui/packager.xml file show the corresponding configuration:
42  *
43  * <button name="add item" orphan="false" register="" submit="true" disable="false">
44  * ...
45  * <srvListener object = "AddFile_listener"/>
46  * </button>
47  *
48  * The tag <srvListener> connects the listener object to widget. In this case the attribute "object" is used
49  * which means that initialised instance of a listener object has to be available. This instance is created
50  * by the following xScript call in the file xml_script/packager_init.xml:
51  *
52  * <Declare objname = "AddFile_listener" objtype = "packager.listeners.AddFile_li" objctx = "forever"/>
53  *
54  * It is also possible to use the attribute "class" whithin the <srvListener> tag to add a new instance
55  * (presumed the availability of a parameterless cunstructor - you find an example with a paramtrized
56  * constructor in "GetInput_li.java") of a listener. In this case you don't
57  * have to use any xScripts. It would look like this:
58  *
59  * <srvListener class = "packager.listeners.AddFile_li"/>
