@mikael Thanks for the pull to refresh example. I really appreciate the help. I had a couple issues. The biggest issue was only being able to refresh once after the view is loaded. The second Issue was when pulled too far down, the refresh function was called multiple times. I think I solved these issues. I attached the solution I came up with below.
import ui, sound class scrollViewDelegate: maxPull = -100 def __init__(self): self.refresh = False def scrollview_did_scroll(self, scrollview): x, y = scrollview.content_offset if y <= 0: delta = max(y, self.maxPull) / self.maxPull if (y <= self.maxPull and not scrollview.tracking and scrollview.decelerating and not self.refresh): scrollview['refresh_bg'][ 'refresh_label'].text_color = 0.50, 0.50, 0.50, delta self.contentRefresh() elif (y <= self.maxPull - 10 and scrollview.tracking and not scrollview.decelerating and not self.refresh): scrollview['refresh_bg']['refresh_label'].text = 'Release to refresh' scrollview['refresh_bg'][ 'refresh_label'].text_color = 0.50, 0.50, 0.50, delta elif (y >= self.maxPull - 10 and scrollview.tracking and not scrollview.decelerating and not self.refresh): scrollview['refresh_bg']['refresh_label'].text = 'Pull to refresh' scrollview['refresh_bg'][ 'refresh_label'].text_color = 0.60, 0.60, 0.60, delta def contentRefresh(self): self.refresh = True sound.play_effect('ui:click3') #print('refreshing') ui.delay(self.contentDidRefresh, 0) def contentDidRefresh(self): self.__init__() w, h = ui.get_screen_size() sv = ui.ScrollView() sv.name = 'Scrollview' sv.always_bounce_horizontal = False sv.always_bounce_vertical = True sv.directional_lock_enabled = True sv.scroll_indicator_insets = (10, 0, 10, 0) sv.bounces = True sv.paging_enabled = False sv.indicator_style = 'black' sv.scroll_enabled = True sv.background_color = 1.0, 1.0, 1.0 sv.content_inset = (0, 0, 0, 0) sv.content_size = (w - 10, h*2) sv.delegate = scrollViewDelegate() rb = ui.View() rb.name = 'refresh_bg' rb.alpha = 1.0 rb.background_color = 0.90, 0.90, 0.90 rl = ui.Label() rl.name = 'refresh_label' rl.alpha = 1.0 rl.alignment = ui.ALIGN_CENTER #rl.background_color = 'white' rl.text = 'Pull to Refresh' rl.text_color = None rl.font = ('<system>', 14) rb.add_subview(rl) sv.frame = (0, 0, w, 0.5) rb.frame = (0, -600, sv.width, 600) rl.frame = (0, rb.height - 32, sv.width, 32) sv.add_subview(rb) sv.present('fullscreen')

@mikael @Stephen Thanks for the quick responses.
I’ve never really dabbled in Python, I’ve just started to really try and teach myself so I could build an app to help manage my shop at work. I was trying to build a pull to refresh function into my scroll view. I’m just working on trying to make sense of all this and make something useful I can add to my app later. I’ll give it a go this weekend and see what I can accomplish. -

is there an example of how you get a scroll view to recognize touch events?
