Application type

Type Parameter

Syntax {$APPTYPE GUI} or {$APPTYPE CONSOLE}

Default {$APPTYPE GUI}

Scope Global

Remarks

The $APPTYPE directive controls whether to generate a Win32 console or graphical UI application.

In the {$APPTYPE GUI} state, the compiler generates a graphical UI application. This is the normal state for a Delphi application.

In the {$APPTYPE CONSOLE} state (equivalent to the /CC command-line option), the compiler generates a console application. When a console application is started, Windows creates a text-mode console window through which the user can interact with the application. The Input and Output standard text files are automatically associated with the console window in a console application.

The IsConsole Boolean variable declared in the System unit can be used to detect whether a program is running as a console or graphical UI application.

The $APPTYPE directive is meaningful only in a program. It should not be used in a library, unit, or package.
