Almost exactly the same way. If you are only interested in failure:
public void foo() {
image.addErrorHandler(new ErrorHander() {
public void onError(ErrorEvent event) {
...
}
});
}
Or if you are interested in both success and failure, your class can
implement both interfaces or you can to synthesize a third interface
that combines them:
public void foo() {
interface WinAndLose extends LoadHandler, ErrorHander { }
WinAndLose wal = new WinAndLose() {
public void onLoad(LoadEvent event) {
}
public void onError(ErrorEvent event) {
...
}
}
image.setErrorHandler(wal);
image.setLoadHandler(wal);
}
