radio-button

问题 a simple question (not so simple for a tkinter newby like me): I'm building a GUI and I want to have two radio buttons driving the status (enabled or disabled) of an Entry widget, into which the user will input data. When the first radio button is pressed, I want the Entry to be disabled; when the second radio button is pressed, I want the Entry to be disabled. Here is my code: from Tkinter import * root = Tk() frame = Frame(root) #callbacks def enableEntry(): entry.configure(state=ENABLED)

问题 Adding radio buttons to a button group limits the user to selecting any one radio button (or none). Is there a way of limiting the user to selecting up to n radio buttons, where n is more than 1 but less than the total number of buttons? In my current case, I am converting a 2D point on a drawing into the theoretical 3D space that the 2D drawing describes. Any one 2D point might represent multiple points in 3D space, so the user has the option to constrain the 3D point by specifying the value

问题 In my Angular 2 project there is ngModel and the radio button doesn't check it <input type="radio" id="user" name="user" value="RETAIL" [(ngModel)]="myRadio" check> But when I cut the ngModel it check <input type="radio" id="user" name="user" value="RETAIL check> But I can't cut it because I need ngModel , is there another way to check radio button on the load page with ngModel ? 回答1: If the value of the input element is a string literal, declare it using one of the two following forms:

问题 I'm trying to build a simple online quiz using Flask and Python 3.6, using HTML forms with radio buttons to carry the selected answers between Flask routes. The first step is to select a category for the quiz, before leading to the actual quiz page, as follows: app = Flask(__name__) categories = ['Europe', 'South America', 'North America'] @app.route('/') def select(): return render_template('selecting.html', cats= categories) @app.route('/quiz', methods = ['POST']) def quizing(): selected

问题 it is my first time using tkinter. I have an entry box on the first window, and I created radio buttons on different windows. The problem is that they are already selected before I click any of them. How can I change all buttons to be deselected? I am not sure if my codes are right or not. from tkinter import * from tkinter import messagebox class SortingHat: # Constructor def __init__(self): # Create main window self.__main_window = Tk() self.__main_window.geometry('300x200') self.__main
