Text mode rendering (TUI mode)

What is the text mode (TUI)?

The text user interface (TUI) has been designed for character-based terminals. This mode can be used to run your application on a text terminal hardware or in a terminal emulator.

In TUI mode, all application forms will display within the current terminal device or emulator as shown.

Enabling text mode

In order to run a Genero program on text mode, set the FGLGUI environment variable to 0 (zero).

Important: On UNIX™ platforms, you need to configure your terminal capabilities with the TERM, TERMINFO or TERMCAP environment variables.

Checking for text mode in programs

In the program code, use the ui.Interface.getFrontEndName() method to query for the front-end type.

When this method returns "console", the program executes in text mode.
