如何在GUI中显示结果？

Question

#this picks a random number
def roll_dice():
    from random import randint
    for x in range(2):
        print(randint(1,6))
#this makes the GUI
from tkinter import *
root = Tk()
root.title('first GUI')
root.geometry('500x500')
app = Frame(root)
app.grid()
label = Label(app, text = 'Dice Simulator')
label.grid()
button1 = Button(app, text = 'Roll Dice', command = roll_dice)
button1.grid()
root.mainloop()

我用它来模拟滚动两个骰子并显示结果。这是我作为程序员的第一个项目，也是我第一次制作tkinter的经历

您希望始终在程序顶部导入模块，这样您的代码就更容易阅读。

要显示roll_dice的结果，您需要先在文本框中显示结果。我打电话给这个方框output你可以这样做：

output = Text(root, height=1, width=5) #create the output box
output.place(x=100,y=100) #place the output box at desire place on the UI

现在要在output框中显示结果，我们可以使用insert Tkinter函数。执行以下操作：

output.delete('1.0', END)     #clears the output box
output.insert(END, randint(1,6))   #insert the result into the

使用您的代码，它应该如下所示：

def roll_dice():
    for x in range(2):
        output.delete('1.0', END)     #clears the output box
        output.insert(END, randint(1,6))   #insert the result into the output box
#this makes the GUI


root = Tk()
root.title('first GUI')
root.geometry('500x500')
app = Frame(root)
app.grid()
label = Label(app, text = 'Dice Simulator')
label.grid()
button1 = Button(app, text = 'Roll Dice', command = roll_dice)
button1.grid()
output = Text(root, height=1, width=5) #create the output box
output.place(x=100,y=100) #place the output box at desire place on the UI

root.mainloop()

结果：
