The _ALLOWFULLSCREEN statement allows setting the behavior of the ALT+ENTER combo.
Syntax
- _ALLOWFULLSCREEN [{_STRETCH|_SQUAREPIXELS|OFF|_ALL}][, {_SMOOTH|OFF|_ALL}]
Description
- Calling the statement with no parameters enables all four possible full screen modes (and is the default state when a program is started): both _STRETCH (_SMOOTH and _OFF) and _SQUAREPIXELS (_SMOOTH and _OFF).
- Using _ALLOWFULLSCREEN _ALL, _ALL has the same effect.
- _ALLOWFULLSCREEN only affects the behavior of ALT+ENTER. The _FULLSCREEN statement is not bound by _ALLOWFULLSCREEN's settings so all modes can be accessed programmatically.
- To limit just the mode but allow both _SMOOTH + _OFF antialiasing modes, pass just the first parameter: Example: _ALLOWFULLSCREEN _SQUAREPIXELS
- To allow multiple modes with _SMOOTH or _OFF as default, pass just the second parameter. Example: _ALLOWFULLSCREEN , _SMOOTH
- Any possible permutation of the parameters is allowed.
- With _ALLOWFULLSCREEN _OFF you can trap Alt+Enter manually in your program and reassign it. See example 2 below.
Availability
- Version 1.3 and up.
Examples
Example 1: Allowing only one fullscreen mode with square pixels and no antialiasing:
_ALLOWFULLSCREEN _SQUAREPIXELS , OFF |
Example 2: Disabling _FULLSCREEN with Alt+ENTER so the combo can be manually trapped:
DO CLS LOCATE 7 PRINT " - Press ALT+ENTER to test trapping the combo..." PRINT " _ Press SPACEBAR to allow fullscreen again..." k& = _KEYHIT IF k& = 13 THEN IF _KEYDOWN(100307) OR _KEYDOWN(100308) THEN altEnter = altEnter + 1 END IF ELSEIF k& = 32 THEN fullscreenEnabled = NOT fullscreenEnabled END IF LOCATE 14 IF fullscreenEnabled THEN _ALLOWFULLSCREEN _ALL , _ALL altEnter = 0 PRINT "_ALLOWFULLSCREEN _ALL, _ALL" LOCATE 18 PRINT "ALT+ENTER will trigger all four fullscreen modes now." ELSE _ALLOWFULLSCREEN OFF PRINT "_ALLOWFULLSCREEN OFF" END IF IF altEnter THEN LOCATE 18 PRINT "ALT+ENTER manually trapped"; altEnter; "times." END IF _DISPLAY _LIMIT 30 LOOP |
