public class LoginForm
extends CustomComponent

LoginForm is a Vaadin component to handle common problem among Ajax applications: browsers password managers don't fill dynamically created forms like all those UI elements created by Vaadin.

For developer it is easy to use: add component to a desired place in you UI and add LoginListener to validate form input. Behind the curtain LoginForm creates an iframe with static html that browsers detect.

Login form is by default 100% width and height, so consider using it inside a sized Panel or Window.

Login page html can be overridden by replacing protected getLoginHTML method. As the login page is actually an iframe, styles must be handled manually. By default component tries to guess the right place for theme css.

Since:

5.3
