The _FULLSCREEN statement attempts to make the program window fullscreen.


Syntax

_FULLSCREEN [_STRETCH|_SQUAREPIXELS|_OFF][, _SMOOTH]


Parameters

  • _STRETCH default first choice attempts to mimic QBasic's full screens if possible. _FULLSCREEN (function) returns 1.
  • _SQUAREPIXELS alternate choice enlarges the pixels into squares on some monitors. _FULLSCREEN returns 2
  • _OFF turns _FULLSCREEN off after full screen has been enabled. _FULLSCREEN (function) returns 0.
  • Second optional parameter _SMOOTH applies antialiasing to the stretched screen.


Description

  • Set the SCREEN mode and text WIDTH when necessary first. Otherwise there may be desktop view issues.
  • _FULLSCREEN with no parameters chooses _STRETCH or _SQUAREPIXELS (prioritizes _STRETCH to mimic QBasic if possible)
  • Check the fullscreen mode with the _FULLSCREEN function in your programs when a method is required.
  • It is advisable to get input from the user to confirm that fullscreen was completed or there were possible monitor incompatibilities.
  • If fullscreen is not confirmed with a _FULLSCREEN (function) return greater than 0, then disable with _FULLSCREEN _OFF.
  • NOTE: _FULLSCREEN can also be affected by custom _FONT size settings and make program screens too large.


Examples

Example 1: Setting the screen mode first prevents enlargement of the desktop before the program window is set: 

SCREEN 12
_FULLSCREEN
IF _FULLSCREEN = 0 THEN _FULLSCREEN _OFF 'check that a full screen mode initialized

LINE (100, 100)-(500, 400), 13, BF

Example 2: How fonts and _FULLSCREEN affect the program's window size. 

SCREEN 0
DO
    PRINT
    LINE INPUT "Enter MODE 1) ENLARGE WINDOW  2) FULL _SQUAREPIXELS  3) FULL _STRETCH: ", WMODE$

    SELECT CASE ENLARGE%
        CASE 1, 2, 3, 4, 5: STYLE$ = "MONOSPACE, BOLD"
        CASE 6, 7, 8, 9: STYLE$ = "MONOSPACE"
        CASE ELSE: STYLE$ = "MONOSPACE"
    END SELECT

    SELECT CASE WMODE$
        CASE "1"
            full = _FULLSCREEN
            IF full > 0 THEN _FULLSCREEN _OFF
            f& = _LOADFONT("c:\windows\fonts\lucon.ttf", 13 + ENLARGE%, STYLE$)
            _FONT f&
        CASE "2"

    END SELECT

    mode = _FULLSCREEN

    PRINT "_FULLSCREEN mode ="; mode,
    PRINT "PRESS ESC TO END OR ENTER TO CONTINUE..."

    DO: SLEEP: B$ = INKEY$: LOOP UNTIL B$ = CHR$(13) OR B$ = CHR$(27)

    GOSUB ClearFont

LOOP UNTIL B$ = CHR$(27)
GOSUB ClearFont
END

FCHECK:

    IF TIMER < Z3 THEN Z3 = Z3 - TIMER
    IF TIMER - Z3 > 4 THEN EXIT DO

PRINT "    2 for _STRETCH"
PRINT "    3 for _SQUAREPIXELS"
PRINT "    4 for _STRETCH, _SMOOTH"
