GUI中的Tkinter函数打印

Question

我用 2 个 api 做了一个程序，显示用户选择的不同城市的预测和城市信息。但现在我需要帮助，因为我坚持如何让我的 make_request、make_requests 和 city_data 在 GUI 中打印信息！我想我需要一个标签，但我不知道该怎么做，任何提示/帮助都会很棒！谢谢：

from tkinter import *
import requests
import json

    class Application(Frame):

        def __init__(self, master=None):
            Frame.__init__(self, master)
            self.root = master
            self.pack()
            self.create_widgets()


        def create_widgets(self):
            self.var = StringVar()
            self.countryImage = Label(self, textvariable=self.var, text=self.var.get)
            self.countryImage.pack(side="top")

            self.var.set("The Tripinator" '\n' "Welcome to Tripinator!" '\n' "To get forecast, enter a country and city then press forecast." '\n'"To get tips, JUST enter city then choose beetween Eat / Drink / Party / Shop / Outdoor!")
            self.var.get()

            self.enterCountry = StringVar()
            self.inputCountry = Entry(self, textvariable=self.enterCountry)
            self.inputCountry.pack(side="left")

            self.enterCountry.set("Enter Country")
            self.enterCountry.get()
            self.inputCountry.focus_set()

    rot = Tk()
    rot.geometry("900x650+200+50")
    rot.title("The Tripinator")

    app = Application(master=rot)
    app.mainloop()

Answer 1

如果您只想模拟打印到控制台，您应该使用文本小部件。文本小部件是显示多行数据的正确选择。不用调用 print，而是调用 insert：

def create_widgets(self):
    ...
    self.out = Text(self)
    ...

def make_request(self):
    r = requests.get(...)
    data = r.json()
    self.out.insert("end", data)
    ...

如果您只想显示几条数据，可以使用标签小部件，并使用config 方法更改其中显示的内容。例如：

def create_widgets(self):
    ...
    self.label1 = Label(self, ...)
    self.label2 = Label(self, ...)

def make_request(self):
    ...
    self.label1.configure(text=something)
    self.label2.configure(text=something_else)

Answer 2

示例 - 我使用带有标题的现有标签来设置请求中的信息

def make_request(self):
    r = requests.get("http://api.wunderground.com/api/61418d709872f773/forecast/q/" + self.enterCountry.get() +"/" + self.v.get() +".json")
    data = r.json()
    for day in data['forecast']['simpleforecast']['forecastday']:
        self.var.set( day['date']['weekday'] + ":" + "\n" + "Conditions: " + day['conditions'] + "\n" + "High: " + day['high']['celsius'] + "C " + "Low: " + day['low']['celsius'] + "C" )
    return data
