Class QTPlayerEventHandler

+--quicktime.app.players.QTPlayerEventHandler
Direct Known Subclasses: QTPlayerAWTEventHandler
public abstract class QTPlayerEventHandlerextends java.lang.Object
When a QTPlayer is addedTo some kind of display space it receives
an addedTo (or removedFrom) notification. At this point the QTPlayer
will dispatch to the QTPlayerEventHandler to return a QTPlayerEventHandler
which will handle all of the events that are generated from the source of interest
that the player has been added to.
Applications can install custom event handler for the QTPlayer and in this construction
process custom event handlers will be made first. If not custom event handlers are appropriate
and a default handler exists it will be made and returned. The first event handler that is
found will be returned as the event handler for any given QTPlayer.
The QTPlayerEventHandler is expected to handle all events for the QTPlayer.
