@short implements a normal frame of hierarchy
@descr An instance of these class can be a normal node in frame tree. A frame support influencing of his
subtree, find of subframes, activate- and deactivate-mechanism as well as
set/get of a frame window, component or controller.
@attention This implementation supports three states: a)uninitialized, b)working, c)disposed
If you call wrong methods in modes a) or c) ... you will get some exceptions.
How you should work with this service:
i) create it by using "xServiceManager->createInstance(...)"
ii) call XInitialization::initialize() with a valid window reference or use createInstanceWithArguments() at i)
iii) works with object
iv) dispose object by calling XComponent::dispose()
After iv) all further requests are rejected by exceptions! (DisposedException)
@base TransactionBase
help to implement unbreakable interface calls
@base OBroadcastHelper
OPropertySetHelper
implements the property set
@base OWeakObject
provides the refcount and XInterface, XWeak
@devstatus ready to use

@short standard constructor to create instance by factory
@descr This constructor initialize a new instance of this class by valid factory,
and will be set valid values on his member and baseclasses.
@attention a) Don't use your own reference during an UNO-Service-ctor! There is no guarantee, that you
will get over this. (e.g. using of your reference as parameter to initialize some member)
Do such things in DEFINE_INIT_SERVICE() method, which is called automatically after your ctor!!!
b) Baseclass OBroadcastHelper is a typedef in namespace cppu!
The microsoft compiler has some problems to handle it right BY using namespace explicitly ::cppu::OBroadcastHelper.
If we write it without a namespace or expand the typedef to OBrodcastHelperVar<...> -> it will be OK!?
I don't know why! (other compiler not tested .. but it works!)
@seealso method DEFINE_INIT_SERVICE()
@param xContext is the multi service manager, which creates this instance.
The value must be different from NULL!
@onerror ASSERT in debug version or nothing in relaese version.

@descr Normaly we don't need this information really. But we can use it to

Algorithm: - first we have to check if we are a top (task) frame
It's not enough to be a top frame! Because we MUST have the desktop as parent.
But frames without a parent are top too. So it's not possible to check isTop() here!
We have to look for the type of our parent.
- if we are a task frame, then we have to check if we are the first one.
We use a static variable to do so. They will be reset to afterwards be sure
that further calls of this method doesn't do anything then.
- Then we have to trigger the right event string on the global job executor.
