问题 I wanted to make a simple pop-up message that shows the name of the options represented as icons when the mouse enters them and hide when it leavs. This icons are images within buttons, and I have been able to show the message when entering the button using a Menu widget, but when the mouse leaves the button it dose NOT unpost, unless there's a klick. I tryed deleting the cascade, but the same happens, the difference is that he menu at that moment has no text. I tryed to .destroy() the menu

问题 I've got a list of attributes such as cost, price, isObsolete etc. which I would like to dynamically generate as a label with an Entry field underneath, for the user to insert the correct value into. It seems the best way to do this is to store the attributes against the values in a dictionary, and update this dictionary whenever the Entry field is updated.

问题 Right now this would work, but I would prefer to do it with for loops and a list. I've tried, but I cannot figure out how to get the name of the buttons that were created in the for loop. import tkinter as tk def toggle(button): #---------------------------- # Manages the button toggling #---------------------------- if button == 0: if button0.config('relief')[-1] == 'sunken': button0.config(relief='raised') else: button0.config(relief='sunken') if button == 1: if button1.config('relief')[-1]
