Class: SynchronousWindowSensorInheritance:Object | +--WindowSensor | +--SynchronousWindowSensor
Description:These sensors are not used with regular views. In contrast to a regular windowSensor, instances of SynchronousWindowSensor do NOT put events into a queue and do NOT wakeup any windowGroup process. Instead, the underlying view is notified synchronously (via a message send) immediately about the event. SynchronousWindowSensor are used for only one single situation: when a super-modal debugger is open (i.e. one that is debugging the scheduler or event-dispatcher). This debugger's windowGroup is augmented with a synchronous Sensor, in order to prevent the event handling code from suspending any process (you cannot suspend the scheduler; you should not suspend the event dispatcher). This is pretty tricky and magic - and you don't have to understand this. (consider this system internal code) Instance protocol:dummy event flushing
