void ChangeBroadcaster::addChangeListener |
( |
ChangeListener * |
listener | ) |
|
Registers a listener to receive change callbacks from this broadcaster. Trying to add a listener that's already on the list will have no effect.
void ChangeBroadcaster::dispatchPendingMessages |
( |
| ) |
|
If a change message has been sent but not yet dispatched, this will call sendSynchronousChangeMessage() to make the callback immediately.
For thread-safety reasons, you must only call this method on the main message thread.
void ChangeBroadcaster::removeAllChangeListeners |
( |
| ) |
|
Removes all listeners from the list.
void ChangeBroadcaster::removeChangeListener |
( |
ChangeListener * |
listener | ) |
|
Unregisters a listener from the list. If the listener isn't on the list, this won't have any effect.
void ChangeBroadcaster::sendChangeMessage |
( |
| ) |
|
Causes an asynchronous change message to be sent to all the registered listeners.
The message will be delivered asynchronously by the main message thread, so this method will return immediately. To call the listeners synchronously use sendSynchronousChangeMessage().
void ChangeBroadcaster::sendSynchronousChangeMessage |
( |
| ) |
|
Sends a synchronous change message to all the registered listeners.
This will immediately call all the listeners that are registered. For thread-safety reasons, you must only call this method on the main message thread.
