问题 I have a kivy app, in which when a button is pressed, it starts communicating with the server and based on information obtained, it creates and fills the screen with widgets. Some actions are almost instant, some take considerable time in seconds. I want to implement a loading popup that is shown while the screen loads. I would also like to do it so that when loading takes less time than some configured time period, lets call it MIN_TIME, the popup does not show at all. Moreover, if the

问题 I searched a lot for it bit i didn't find a solution. I would like to grab a widget in a kivy scatter and get the position of it each time i move it. So it could like so: def onmove_in_scatter(args): x = args[0] y = args[1] print("You are currently here: "+str(x)+":"+str(y)) It's important that the function is called WHILE i move the widget. 回答1: When I want to do something like this I override the on_touch_move. Here is a full* working example. (just put a cat.png somewhere...) import kivy
