/**
* A dispatcher that serves as a proxy for style commands with arguments
* i . e . . uno : StyleApply ? . . . in order to provide useful status updates to
* generic UI elements such as toolbars or menubar . It listens to special
* status commands , and computes a boolean status out of them . Then it
* forwards that boolean status to the listener , as if it was the status
* of the original command .
*
* Note that the implementation is minimal : Although the UI element appears
* to be the owner of the dispatcher , it ' s still responsible , as usual , to
* call removeStatusListener same amount of times as addStatusListener ,
* otherwise the dispatcher might not be destructed . In addition this
* implementation might hold a hard reference on the owner , and it ' s the
* responsibility of the owner to destroy the dispatcher first , in order
* to break the cycle .
