Hello!

Take a look at the documentation section about opening views: Opening Views :: Jmix Documentation.

There is an example of handling QueryParametersChangeEvent:

@ViewComponent
private H1 messageLabel;

public void setMessage(String message) {
    messageLabel.setText(message);
}

@Subscribe
public void onQueryParametersChange(final QueryParametersChangeEvent event) {
    List<String> messageParams = event.getQueryParameters().getParameters().get("message");
    if (messageParams != null && !messageParams.isEmpty())
        setMessage(messageParams.get(0));
}
