dynamically-generated

问题 I really have searched high and wide and i'm starting to think it may be my terminology that is preventing me from finding the answer. I have a MovieClip in my library set to Export to ActionScript 3.0 with a Class called 'Info_Win' (its basically going to be a pop-up window, the contents of which depends on it's instance name). I will be adding a given number of these MovieClips to the main stage and each one has to be given a custom instance name that will allow me to access it once it's on

问题 Beginner to all of this, playing around with Firebase. Basically, I want to retrieve text entries from Firebase and have an "Approve" button next to it. When the button is clicked, I want that specific text entry to be pushed to a new Firebase location and the text removed from the page. I am creating the button and the text dynamically and I am having some trouble with selecting the button and the divs I created. I know I have to use on() but I'm unsure of how to use it. Thanks! approveRef

问题 I have created buttons dynamically and set them to call script function so when Test 1 is clicked script_1 is executed, likewise Test 2 for script_2 and so on... but when Test 1 or Test 2 is clicked script_0 is executed. It appears val = i.get() always returns the value 0 each time. Is there a way to get the current i value ? function def script(): if running: i = IntVar() val = i.get() subprocess.Popen(['python', 'script_' + str(val) + '.py']) root.update() Button for i in range(3): button
