Program Plan Intro

JavaFX:

• JavaFX denotes a library that is used to build internet applications.
• The applications that are written with this library can be made to execute across multiple platforms.
• The applications developed using JavaFX could be executed on devices such as Mobile phones, TVs, tablets as well as desktop computers.
• It provides a rich graphics set as well as media API’s.
• It leverages modern graphical processing unit through hardware accelerated graphics.
• It provides interfaces through which developers can combine UI control as well as graphics animation.
• The additional technologies are not required when JavaFX is been included in program.
• It provides classed for 2D as well as 3D graphics.

Scene builder:

• A scene builder is been used to create a GUI visually.
• It is used to construct a GUI by dropping and dragging components needed on a blank window.
• The components of windows could be arranged visually.
• It sets various properties of components to create required appearance for GUI.
• The GUI is then saved to an FXML file.

Controller class:

• The main application class is responsible for building scene graph and displaying GUI.
• The “controller” class is responsible for handling events that occurs while application is running.
• The items present in “controller” class includes:
  • The necessary “import” statements.
  • Private variables for referencing components with “fx:id” in scene graph.
  • An optional “initialize” method that is been called automatically after FXML file is loaded.
  • Event listener methods.
