/**
 * Opie and Qtopia uses a component system called QCOM
 * which was first part of the Qt 3.0 API but was made
 * prviate during the betas. Opie and Qtopia still use it
 * and we're happy with it.
 * Every starts with the QUnknownInterface. It supports functions
 * for reference counting and the most important one
 * is for a query. Every QCOM interface got a global unique id ( GUID,UUID )
 * query is used to see if a interface is supported by
 * a dynamic shared object ( dso / plugin )
 * For tasks like loading Applications, InputMethods, Today, MenuButton,
 * Taskbar, Style, Email Client there are specefic Interfaces you
 * need to implement. The interfaces inherits from QUnknownInterface and
 * you'll need inherit from the interface.
 * As example we will use the Taskbar interface

/*
 * The taskbar applet interfaces wants us to implement position() and applet()
 * additionally we need to implement add(), release() and queryInterface for QUnknownInterface
 * luckiy there is a macro for the reference counting
 * We provide an Implementation of the interface.
