The '''_FULLSCREEN''' statement attempts to make the program window fullscreen.
|

{{PageSyntax}}
|
||
|
:::_FULLSCREEN [{ ''_OFF | _STRETCH | _SQUAREPIXELS''}]
|
||
|
|

|
||
|
{{PageDescription}}
|
||
|
* The statement can be used in ANY [[SCREEN (statement)|SCREEN]] mode. Set the screen mode (and text [[WIDTH]] when necessary) first!
|
||
|
* _FULLSCREEN can use the following methods:
|
||
|
** '''{{Parameter|_STRETCH}}''' default first choice attempts to mimic QBasic's full screens if possible. _FULLSCREEN function returns 1.
|
||
|
** '''{{Parameter|_SQUAREPIXELS}}''' default second choice enlarges the pixels into squares. _FULLSCREEN function returns 2.
|
||
|
** '''{{Parameter|_OFF}}''' turns fullscreen off after full screen has been enabled. _FULLSCREEN function returns 0.
|
||
|
* If no option/method is specified after _FULLSCREEN, QB64 chooses {{Parameter|_STRETCH}} or {{Parameter|_SQUAREPIXELS}} (note: this prioritizes {{Parameter|_STRETCH}} to mimic QBASIC when possible)
|
||
|
* '''Always''' check the fullscreen mode with the {{KW|_FULLSCREEN (function)|_FULLSCREEN}} function in your programs!
|
||
|
* 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 {{KW|_FULLSCREEN}} _OFF!
|
||
|
* '''NOTE:''' _FULLSCREEN can also be affected by custom [[_FONT]] size settings!
