The _DISPLAY function returns the handle of the current image that is displayed on the screen.
- currentImage& = _DISPLAY
- Returns the current image handle value that is being displayed. Returns 0 if in the default screen image.
- Not to be confused with the _DISPLAY statement that displays the screen when not using _AUTODISPLAY.
Example: Creating a mouse cursor using a page number that you create in memory without setting up page flipping.
SCREEN _NEWIMAGE(640, 480, 32) 'any graphics mode should work without setting up pages _MOUSEHIDE SetupCursor PRINT "Hello World!" DO: _LIMIT 30 DO WHILE _MOUSEINPUT: LOOP 'main loop must contain _MOUSEINPUT ' other program code LOOP SUB SetupCursor ON TIMER(0.02) UpdateCursor TIMER ON END SUB SUB UpdateCursor PCOPY _DISPLAY, 100 'any page number as desination with the _DISPLAY function as source PSET (_MOUSEX, _MOUSEY), _RGB(0, 255, 0) DRAW "ND10F10L3F5L4H5L3" _DISPLAY 'statement shows image PCOPY 100, _DISPLAY 'with the function return as destination page END SUB
Note: Works with the _DISPLAY function return as the other page. If mouse reads are not crucial, put the _MOUSEINPUT loop inside of the UpdateCursor SUB.
