Vcl.Forms.TApplication, Vcl.Forms.TScreen, and Vcl.Forms.TForm are the classes that form the backbone of all applications by controlling the behavior of your project:

  • The TApplication class forms the foundation of an application by providing properties and methods that encapsulate the behavior of a standard program.
  • TScreen is used at run time to keep track of forms and data modules that have been loaded as well as maintaining system-specific information such as screen resolution and available display fonts.
  • Instances of the TForm class are the building blocks of your user interface of the application. The windows and dialog boxes in your application are based on TForm.
