问题 I'm trying to learn how to use py2app in order to create a simple Mac app from a tkinter GUI and am encountering a runtime error when attempting to do so. My Mac is running OS Catalina 10.15.4. I'm using PyCharm 2020.1 with Python 3.7. My original python installation was done using Anaconda and after trying two IDEs (Spyder and IDLE), I switched to PyCharm.

问题 I don't think this is a coding issue, but I would be grateful for some clues. I have some code which turns Tkinter Buttons green or red as they control relays. This works fine on my RaspberryPi but I cannot get any Button background colour except white on my code writing machine a MacPro. I am running Python 3.7.3 and Pycharm 2019.3.4 on both. Raspberian (latest release can’t remember version number) and OSX 10.15.4 on the Mac. When I run from Pycharm, colour can be set for the Window

问题 So I'm trying to print items in a list dynamically on 10 tkinter Label s using a for loop.

问题 I am using code for a multi listbox (http://code.activestate.com/recipes/52266-multilistbox-tkinter-widget/) This is creating columns of data for the user to select from, I would like when the user Listboxselect that the columns from the record get populated into different Entry boxes. I can get this to work in a standard Listbox using .bind .delete .insert within a function but because the data within the dictionary is different sizes it looks ugly:) I would really like to stick with the

问题 I have some code in python using the tkinter module. I've been trying to bind a function to the "<Destroy>" , but each time I run the code and I close the window, the binded function executs 5 times. Here is the code: def bind_events(self): ''' binding the events to their functions ''' self.master.bind("<Destroy>", lambda x: print("OK")) This code is a class function. Then the output I obtain this: >>> OK OK OK OK OK Is there any solution for this problem. Thank you for your time, and sorry
