TApplication = class(TComponent)
class PASCALIMPLEMENTATION TApplication : public System::Classes::TComponent
TApplication is the type used for a FireMonkey GUI-based windowed application.
TApplication encapsulates a windowed application. The methods and properties introduced in TApplication reflect the fundamental actions related to creating, running, sustaining, and destroying a FireMonkey application on Windows and OS X operating systems.
Each GUI application automatically declares an Application variable as the instance of the application.
TApplication does not appear on the Component Palette, nor is it available in the form designer to visually manipulate; so it has no published properties. Nevertheless, some of its public properties can be set or modified at design time in the Forms and Application pages of the Project > Options dialog box.
Tip: For application-wide properties and methods that affect the display, see TScreen.
