FULLSCREEN

Part of: LOGO.ENV

Controls whether to have Terrapin Logo occupy the entire screen or

Syntax

GPROP "LOGO.ENV "FULLSCREEN
PPROP "LOGO.ENV "FULLSCREEN TRUE/FALSE

Description

FULLSCREEN sets Terrapin Logo to fullscreen if its value is set to TRUE, or to normal size if its value is set to FALSE. It reports the current fullscreen setting.

Not all browsers allow a program to occupy the entire screen. In that case, setting the FULLSCREEN property to TRUE does not have any effect.

Also, do not expect any Logo panel to properly report its size immediately after setting the property. The change to fullscreen and back is independent from the execution of a Logo program, and resizing all panels takes some time before Logo is made aware of the changes.

Examples

GPROP “LOGO.ENV “FULLSCREEN Result: FALSE
