Could you please show an example?

Hi, this is OK but the black circle is over the red one, how can we put the black circle behind as background?

Hi everybody, thx for helping, I’ll buy Pyto and try.

Thx for trying, I’ll wait!

Thx, the question is now if Pyto can read the barometer sensor value, below a short code which runs fine under Pythonista:

from objc_util import ObjCInstance, ObjCClass, ObjCBlock, c_void_p

pressure = None

def get_pressure():
  
  def handler(_cmd, _data, _error):
    global pressure
    pressure = ObjCInstance(_data).pressure()

  handler_block = ObjCBlock(handler, restype=None, argtypes=[c_void_p, c_void_p, c_void_p])

  CMAltimeter = ObjCClass('CMAltimeter')
  NSOperationQueue = ObjCClass('NSOperationQueue')
  if not CMAltimeter.isRelativeAltitudeAvailable():
    print('This device has no barometer.')
    return
  altimeter = CMAltimeter.new()
  main_q = NSOperationQueue.mainQueue()
  altimeter.startRelativeAltitudeUpdatesToQueue_withHandler_(main_q, handler_block)
  try:
    while pressure is None:
      pass
  finally:
    altimeter.stopRelativeAltitudeUpdates()
    #print('Updates stopped.')
    return pressure.floatValue()*10

pressure = get_pressure()
print(pressure)

I just downloaded it but my trial period already expired because I probably already tried it some times ago and since I don’t know if it works, I don’t want to buy it. If you’ve it, could you try if it runs when iPad is asleep?

I don’t know PyTo but I will try, thx in any case

@cvp I’m not sure to understand what you mean, but calling a pythonista script from a shortcuts or an automation requires the iPad to be awake

Yes, it works but only if the iPad is awake

Yes but only everyday, I want to read the value of the barometer sensor every hour, I can get this value with Pythonista. I didn’t find a way to get this information in shortcuts nor in JS (scriptable).
I found also a way to do some tasks every hour in shortcuts but I don’t find a way to get the barometer sensor value.

Hi everybody, I could call a Pythonista script from shortcuts using url and safari but it works only if the iPad is awake, is there a way to let it work when the iPad is asleep?
I also tried running a Pythonista script using scheduler but it works only if I stay in the Pythonista app.
What I want to achieve is writing some info into a file every hour

Super, thank you

Thx cvp but I don’t know how to download a module into Pythonista

Whao, I’m impressed, thank you!
But I don’t understand why it doesn’t work in my last example

My last issue is that the drawing doesn’t refresh even when I call explicitly drawTest() as you can see in the example below:

import ui

class my(ui.View):
    
    def __init__(self, *args, **kwargs):
        self.factor = .5

    def draw(self):
        print('draw()')
        self.drawTest()

    def drawTest(self):
        print('drawTest()')
        print('%.1f' % (self.factor))
        w,h = ui.get_screen_size()
        path1 = ui.Path()
        path1.line_width = 3
        ui.set_color('red')
        path1.move_to(100*self.factor,100*self.factor)
        path1.line_to(200*self.factor,100*self.factor)
        path1.line_to(100*self.factor,200*self.factor)
        path1.close()
        path1.fill()
        path2 = ui.Path()#.rect(0,0,w,h)
        path2.line_width = 3
        ui.set_color('blue')
        path2.move_to(300*self.factor,100*self.factor)
        path2.line_to(400*self.factor,100*self.factor)
        path2.line_to(300*self.factor,200*self.factor)
        path2.close()
        path2.fill()
        
    def touch_began(self, touch):
        print('touch_began()')
        self.factor += .5
        self.drawTest()
        
    def will_close(self):
        print('will_close()')
        
v = my()
v.present('fullscreen',hide_title_bar=True)

It redraws only when I turn the iPad, could you please tell me how I can force the refresh with the right zoom factor?

Thx to both of you, concerning the gestures, it seems to be a little bit complicated but I will try

... and then, I need to redraw in order to see the polygons in a different zoom factor. As I wrote, I already tried with ui but I stoped because I could not redraw, that’s why I tried with scene

Yes thx it works but it doesn’t with several polygons

I just want to draw a filled polygone following numerous coordinates, I already managed to do it with ui and canvas but only scene gives me the possibility to use full screen

Hi Mikael, thx for replying but is there a way to avoid this?
