Combine Scene and Ui module
-
Ok, think I got it, but I‘m not sure if it is the best way.
from scene import * import ui class MyScene (Scene): def setup(self): print (self.view.superview['slider1'].value) pass # Define your scene like usual... v = ui.load_view('example.pyui') v['sceneview'].scene = MyScene() v.present('fullscreen') ``` -
setup() is only called once. You might like to call a function/method for changed values. Search for Slider Attributes => Slider.action
not tested:
def setup(self): slider = self.view.superview['slider1'] slider.action = self.slider_changed def slider_changed(self, sender): print(sender.value) -
@brumm Perfect! Works great!

Hey,
another question, which still has to do something with combining scenes and UI ... so I keep asking here. It seems that the scene is part of the UI. What would be the best way to separate them? I mean, how could I achieve a hiding/unhiding UI? Or transforming the position of the UI. Or working with several UIs in one scene at all?
sorry for asking that much at once
rownn -
Ok, I think I got it. After I recognized that it is possible to add UI elements to a CustomView via long pressing and SubViews I solved the stuff this way.
Pythonista makes fun! Great and nice app!!!

@rownn I never tried moving UIs, except for using the bring_to_front() and move_to_back() option. Thanks for positing the solution to your questions, might help me at some point :)
Oh, and Pythonista definitely is a great app
-
Hi, I’d like to try your example
-
@rownn I’d like to run your example posted two months ago but I don’t know how to convert the text for the .pyui file into an actual .pyui file. I’m brand new to Pythonista.
-
@Tey rename the file extention in pyui
-
@wnMark
So simple. Thanks!
