Examples of com.vaadin.terminal.VariableOwner

com.vaadin.terminal.VariableOwner

Listener interface for UI variable changes. The user communicates with the application using the so-called variables. When the user makes a change using the UI the terminal trasmits the changed variables to the application, and the components owning those variables may then process those changes.
