Further such key code can be triggered.

Doing so different accelerator

configurations are merged together; a suitable

command registered for the given key code is searched
|

and will be dispatched.
|
|
|
|
@attention
|
|
|
|
Because exceution of an accelerator command can be dangerous
|
|
(in case it force an office shutdown for key "ALT+F4"!)
|
|
all internal dispatches are done asynchronous.
|
|
Menas that the trigger call doesnt wait till the dispatch
|
|
is finished. You can call very often. All requests will be
|
|
queued internal and dispatched ASAP.
|
|
|
|
Of course this queue will be stopped if the environment
|
|
will be destructed ...

- delete the object

=> If it stands currently in its execute method, they will
|
|
be finished. All further queued requests will be removed
|
|
and further not executed!
|
|
|
|
- "let it stay alone"
|
|
=> All currently queued events will be finished. The
|
|
helper kills itself afterwards. A shutdown of the
|
|
environment will be recognized ... The helper stop its
|
|
work immediatly then!
