/**

* 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

* We provide an Implementation of the interface.
