Bug in pages or in program ?
Posted: Fri Dec 13, 2024 11:48 am
Apparently my question about a possible bug has gone unnoticed.
See https://nitisara.ru/forum/viewtopic.php ... 627#p15627
That's why I posted it here in the hope that someone can help.
I've been trying to make a background for a custom toolbar for some time now, but I can't.
I want to create the toolbar in a separate page that remains visible and then return to the default page "" on which the program should generate the output.
The code below gives a minimal example:

IF BUTTON_PRESSED("stop") THEN RETURN 0
RETURN 1 ' from function
CreateButton:
' create all toolbar buttons
ypos=-6
FILL COLOR 0,0,0
DRAW COLOR 1,1,1
FILL ALPHA 0
DRAW ALPHA 1
BUTTON "stop" TEXT "stop" AT int(sw*.4),ypos
init=1
END DEF

If you run that program, you will see circles drawn from the center of the screen to the top, after which the program stops.
If you remove the "REM" statement after the "Checkbutton:" label, the program will display a colored top bar, but only draw one circle and stop after the usual time. While running, the program can be stopped prematurely by pressing "stop" in the top bar.
Why don't the other circles appear?
How can I fix this?
