  I tried it with scene

  from scene import Scene, Node, LabelNode, run class quiz(Scene): def __init__(self): super().__init__() self.pages = [] def setup(self): self.page_now = -1 self.buttons = Node() self.add_child(self.buttons) temp = LabelNode("start quiz?") temp.position = self.size/2 self.buttons.add_child(temp) def touch_began(self, touch): for i in self.buttons.children: if touch.location in i.bbox: if self.page_now < len(self.pages)-1: self.next_page() print("userer picked:", i.text) else: print("end of quiz") def next_page(self): self.buttons.remove_from_parent() self.page_now += 1 question, values = self.pages[self.page_now] page = Node() num_of_nodes = len(values) + 1 h = self.size.h / num_of_nodes w = self.size.w x = self.size.w * 0.5 but = LabelNode(question, font=('Helvetica', 40)) values.append("") for i in range(len(values)): but.anchor_point = (0.5, 1) but.position = (x, self.size.y - (h*i)) but.y_scale = min(w / but.size.x, h/but.size.y) but.x_scale = min(w / but.size.x, h/but.size.y) page.add_child(but) but = LabelNode(values[i], font=('Helvetica', 40)) self.buttons = page self.add_child(page) def add_page(self, question, values): self.pages.insert(-2, (question, values)) if __name__ == "__main__": app = quiz() app.add_page("do you like this code", ["yes", "no"]) app.add_page("do you understand this code", ["yes", "no", "whats code lol"]) app.add_page("if you add lots of text it gets smallergggggggggggggggggggggggggggggggggggggggg", ["oh ok, cool"]) run(app)

  @mikael perfect, that does exactly what I wanted. Combined with guided access mode on the iPad, once the python program starts to run the user shouldn’t be able to leave the view at all.

  But if anyone wants to use this code, I have edited the button function so it will eventually let you out, unfortunately I am not as elegant as @mikael

  Cheers

  #coding: utf-8 import ui, random from ui import * from objc_util import * def button_tapped(sender): rn=random.random() if rn <0.8: sender.title = 'unlucky, click again to close' button.size_to_fit else: view.close() UILayoutContainerView = ObjCClass('UILayoutContainerView') UISwipeGestureRecognizer = ObjCClass('UISwipeGestureRecognizer') def disable_swipe_to_close(view): v = view.objc_instance while not v.isKindOfClass_(UILayoutContainerView.ptr): v = v.superview() for gr in v.gestureRecognizers(): if gr.isKindOfClass_(UISwipeGestureRecognizer.ptr): gr.setEnabled(False) view = ui.View() view.background_color = (0.3,0.31,0.32) button = ui.Button(title='Click this button to close view') button.center = (view.width * 0.5, view.height * 0.5) button.flex = 'LRTB' button.action = button_tapped view.add_subview(button) view.present('fullscreen', hide_title_bar=True) disable_swipe_to_close(view)

  @midas9087, you can allow ”unsafe browsers” from Google settings, if I recall correctly. Unsafeness had maybe something to with SSL/TLS versions.

  @Cethric made a full GLKit wrapper, which might do what you want.
  In scene, you will be limited to converting each frame to .jpg by using the SceneView screen capture method, i think, since there is no way to get data out of a shader.

  @shinya.ta In topic , which code did you try because the topic shows an evolution of code.
  I wrote this code but you will not find a solution to the globe key there.

  Notification/Callback/Hooks when ui.View is presented or closed?

  Here is a way to capture all notifications:
  https://github.com/jsbain/objc_hacks/blob/master/notification_capture.py

  This could be modified to observe a specific object, selector, etc. I believe there is a notification when a view is shown, but i didnt see an obvious one when the X is pushed.

  The confusing thing about what you are asking is that sheet is already basically modal, since it blocks anything else happening. in which case wait_modal might be what you want.

  For truly non-modal "windows", you might consider the Overlay, found here. This lets you create resizable views that float, and you can use connect to register actions that get called when the view is closed.

  Finally, it would be possible to delete the standard X, and replace it with your own button.

  v.objc_instance.superview().superview().superview().subviews()[1].subviews()[1]

  gives me the X button on ipad when presenting as sheet. This might be different on iPhone, and might be different if you have leftbuttonitems or rightbuttonitems defined.

  But this lets you, for instance, hide the default X, and define your own using right_button_items.

  v=ui.View() def c(sender): v.close() print('closed') v.right_button_items=[ui.ButtonItem(action=c,title='X')] v.present('sheet') v.objc_instance.superview().superview().superview().subviews()[1].subviews()[1].hidden=True

  i'm pretty sure that numba is not created in raw python, therefor it cannot be used with pythonista, especially if you are downloading it using stash.

  See https://stackabuse.com/how-to-send-emails-with-gmail-using-python/

  You seem to be missing the ehlo/helo, which i think google uses to help prevent ddos. also, if you didnt have a time.sleep in there, you may have been flagged as a bad user. you are limited to 20 messages per second or something. also, i think google prefers that you connect to one session to send multiple messages rather than connect once per message.

  check those bounce messages to see if there are any errors shown.

  @cvp Thank you for your information. I got "Hello World !!" message by transmitting the result of script via clipboard. I misunderstood the specification of "Run script" action Because the quality of translated documentation of actions is a bit worse.

  I made a tree drawing thing a couple of years when I saw this vid, I recommend checking out some of his other videos, they aren’t in python but it’s some really nice concepts and he explains them in terms that can translate to other languages

  from ui import ImageContext, Path, set_color, fill_rect from math import sin, cos, pi from random import random #help(random) def r(x, y, t): # t = t +(random() -0.5)*0.5 return x*cos(t) - y*sin(t), y*sin(t) + x*cos(t) class tree: def __init__(self): self.startlen = 50 self.maxit = 9 self.th = 5*pi/4 self.thl = pi/12 self.thr = -pi/12 self.p = Path() self.short = 0.85 self.size = 1000 def draw(self): self.p = Path() self.stopn = self.startlen * (self.short ** self.maxit) with ImageContext(self.size, self.size) as cx: set_color((255,255,255)) fill_rect(0,0,self.size, self.size) set_color((0,0,0)) self.p.line_width = 0.9 self.p.move_to(self.size/2, self.size) self.branch(self.startlen, self.size/2, self.size*4/5, 5*pi/4) self.p.stroke() cx.get_image().show() def branch(self, len, x, y, t): self.p.line_to(x, y) if len > self.stopn: self.p.move_to(x,y) x1, y1 = r(len, len, self.thl+t) self.branch(len*self.short, x+x1, y+y1, self.thl+t) self.p.move_to(x,y) x1, y1 = r(len, len, self.thr+t) self.branch(len*self.short, x+x1, y+y1, self.thr+t) #self.branch(len*self.short, x+x1, y+y1, self.thr+t) self.p.move_to(x,y) if __name__ == '__main__': s = tree() #s.thl += 0.25 #for i in range(100): s.draw()

  @JonB, still, can be difficult to tell where the error really comes from, when you have these bits and pieces of eval_js flying around.
