* ECOM plug-in creation for the standalone application.
|
|
28 |
* The view class must inherit this class to be able to signal the
|
|
29 |
* destruction of the interface implementation. If this implementation
|
|
30 |
* was created in the GS application, the destruction must not be
|
|
31 |
* signalled, since the view framework does it. If this implementation
|
|
32 |
* was created in the standalone USB UI application, the destruction
|
|
33 |
* must be signalled, since otherwise there will be memory leaks.
|
|
34 |
*
|
|
35 |
* The inherited CGSPluginInterface destructor does not signal the
|
|
36 |
* desctruction. Also, it cannot be signalled in the destructor of
|
|
37 |
* this class, since it would be called while deleting the view.
|
|
38 |
* This class stores the instance ID iDtor_ID_Key, because it can't
|
|
39 |
* access the private member variable of class CGSPluginInterface.
|
|
40 |
*
|
|
41 |
* Note that the implementation is inline, because the concrete
|
|
42 |
* plug-in has not been loaded. The implementation of this class can't
|
|
43 |
* reside in the plug-in to be loaded by the ECOM framework.
