Hy,
I have the same Problem. I tried the solution of Paul Robinson, but
nevertheless, nothing happens.
Where is my mistake? Here is my code:
public static ScrollPanel scrollPanel;
// ...
private void loadInputFunctions() {
input.addKeyDownHandler(new KeyDownHandler() {
@Override
public void onKeyDown(KeyDownEvent event) {
if (event.getNativeKeyCode() == KeyCodes.KEY_ENTER) {
// ...
}
input.setText(">>");
Scheduler.get().scheduleDeferred(
new Scheduler.ScheduledCommand() {
@Override
public void execute() {
scrollPanel.scrollToBottom();
}
});
}
}
});
}
Thanks in advance.
