Stage is the top level container in JavaFX. It provides attributes such as fullScreen, iconified, opacity, style, icons, resizable, title which loosely maps to corresponding methods in java.awt.Frame. But it doesn’t provide any functionality to create Dialog behavior (modal, no task bar icon etc) and also support for setAlwaysOnTop. These two features are required to get the actual Widget feel. As of now the Stage shows a taskbar icon for each application.
