following code in red has been removed in vaadin 7 , i am doing vaadin 6 to 7 migration . 

What should be the equivalent code that has to be follwed here . 

FYI: PasswordChangeForm  : Form class in vaadin 6 
even if depricated ,  form.getWindow() method is removed . How to handle this 

In this case addListener -> addClickListener -- depends on the type of listener you are trying to add.

As for the Window thing, in Vaadin 6 you were always in a Window, but this is not the case in Vaadin 7. Windows are basically only meant for popups, although you can cover the whole browser window with it still. What you want to do in that part of your code depends on how you have changed other parts of your code. If there is still a Window parent that you need to remove you could for example give that as a reference to the form and add the getter yourself, or you could iterate through parents until you find one that is instanceof Window. If your form is no longer in a Window you'll need to change the view by some other means.
