Question

如何将此代码放入gui？我尝试将其添加到按钮中，但失败了！

我希望所有def say_hi(self)都在gui中，而不是将其打印到shell中，而且打印输出在控制台中效果最好，而不是python shell！

import sys
import time
from random import randint
import tkinter as tk
class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.pack()
        self.create_widgets()
        # self.roll is the button 

    def create_widgets(self):
        self.roll = tk.Button(self)
        self.roll["text"] = "rolldice"
        self.roll["command"] = self.say_hi
        self.roll.pack(side="left")
        #self.quit is the kill button
        self.quit = tk.Button(self, text="QUIT", fg="red",
                              command=root.destroy)
        self.quit.pack(side="right")
        self.label = tk.Label(self, text='ROLL THE DICE !')
        self.label.pack()
        # this is my loading result.

    def say_hi(self):

        d = 0
        for x in range(0,7):
            for x in range (0,5):  
                b = "Loading" + "." * x
                a = "                           "
                print (b, end="\r")
                time.sleep(0.1)
                print (a, end="\r")
                time.sleep(0)

        print("finished rolling!")
        time.sleep(2)
        for x in range(0,7):
            for x in range (0,5):  
                b = "printing" + "." * x
                a = "                           "
                print (b, end="\r")
                time.sleep(0.1)
                print (a, end="\r")
                time.sleep(0)
        print ("printed")
        print ("here it is thankyou for using us!")
        print ("                                          ")
        value = randint(1, 6)
        self.label['text'] = value
        self.label.pack()


root = tk.Tk()
app = Application(master=root)
app.mainloop()

Answer 1

您可以使用Lable和StringVar。

Label小部件是标准的Tkinter小部件，用于在屏幕上显示文本或图像。标签只能显示单一字体的文本，但是文本可能会跨越多行。另外，可以在其中一个字符下划线，例如，以标记键盘快捷键。

这里check it out!的使用方法很好。

修改

如果您希望用户能够显示用户可以就地操作的数据，则使用Canvas小部件可能会更容易。

希望这会有所帮助！

尝试一下。代替打印 self.label['text'] = b self.label.pack() root.update()

它更新在小部件内部打印的值。

import sys
import time
from random import randint
import tkinter as tk
class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.pack()
        self.create_widgets()
        # self.roll is the button 

    def create_widgets(self):
        self.roll = tk.Button(self)
        self.roll["text"] = "rolldice"
        self.roll["command"] = self.say_hi
        self.roll.pack(side="left")
        #self.quit is the kill button
        self.quit = tk.Button(self, text="QUIT", fg="red",
                              command=root.destroy)
        self.quit.pack(side="right")
        self.label = tk.Label(self, text='ROLL THE DICE !', padx=20)
        self.label.pack()
        # this is my loading result.

    def say_hi(self):

        d = 0
        for x in range(0,7):
            for x in range (0,5):  
                b = "Loading" + "." * x
                a = "                           "
                #self.label.pack_forget()
                self.label['text'] = b
                self.label.pack()
                #root.update_idletasks()
                root.update()
                print (b, end="\r")
                time.sleep(0.2)
                print (a, end="\r")
                time.sleep(0)

        print("finished rolling!")


        for x in range(0,7):
            for x in range (0,5):
                b = "Printing" + "." * x
                a = "                           "
                #self.label.pack_forget()
                self.label['text'] = b
                self.label.pack()
                #root.update_idletasks()
                root.update()
                print (b, end="\r")
                time.sleep(0.2)
                print (a, end="\r")
                time.sleep(0)
        print ("printed")
        print ("here it is thankyou for using us!")
        print ("                                          ")
        value = randint(1, 6)
        self.label['text'] = value
        self.label.pack()

root = tk.Tk()
app = Application(master=root)
app.mainloop()
