[Solved] Adding scrollbar to screen based on iterative size

[revlith]

I'm trying to have a scrollbar only added to the choice screen based on if the options are going offscreen.

I've gotten it so that it consistently has a scroll bar if i uncomment the line beneath the viewport, and the counting works. But all my code does right now is move the options to the left without a scrollbar. I can get it to add a scrollbar to the window if the options go offscreen but that's useless. I have no idea why this doesn't work, please help

Code: Select all

screen choice(items):  
    window:
        style_prefix "choice"
        $ needS = False
        area (350, 100, 1250, 750)
        viewport:
#            scrollbars "vertical"
            vbox:
                spacing 40
                $ count=0
                for i in items:
                    $ count +=1
                    if count >= 9:
                        $ needS = True

                        textbutton i.caption action i.action
                        
                    else:
                        textbutton i.caption action i.action

            if needS:
                scrollbars "vertical"

Try something along the lines of:

Code: Select all

screen choice(items): 
    window:
        style_prefix "choice"
        area (350, 100, 1250, 750)
        viewport:
            if len(items) >= 9:
                scrollbars "vertical"
            vbox:
                spacing 40
                for i in items:
                    textbutton i.caption action i.action
