public interface WalletChangeEventListener
Implementors are called when the contents of the wallet changes, for instance due to receiving/sending money or a block chain re-organize.
void onWalletChanged(Wallet wallet)
Designed for GUI applications to refresh their transaction lists. This callback is invoked in the following situations:
When this is called you can refresh the UI contents from the wallet contents. It's more efficient to use this rather than onTransactionConfidenceChanged() + onReorganize() because you only get one callback per block rather than one per transaction per block. Note that this is not called when a key is added.
