在 GUI 界面 Tkinter Python 中打印输出

Question

from Tkinter import *

def printSomething():
    print "Hey whatsup bro, i am doing something very interresting."

root = Tk()

button = Button(root, text="Print Me", command=printSomething)
button.pack()

root.mainloop()

输出来自我运行代码的终端 我需要GUI界面的输出。

Answer 1

使用 print 只打印到终端或 fp。您可以创建一个新标签以“打印”到 GUI。

from Tkinter import *

def printSomething():
    # if you want the button to disappear:
    # button.destroy() or button.pack_forget()
    label = Label(root, text= "Hey whatsup bro, i am doing something very interresting.")
    #this creates a new label to the GUI
    label.pack() 

root = Tk()

button = Button(root, text="Print Me", command=printSomething) 
button.pack()

root.mainloop()

供您评论的示例

from Tkinter import *

def printSomething():
    # if you want the button to disappear:
    # button.destroy() or button.pack_forget()
    for x in range(9): # 0 is unnecessary
        label = Label(root, text= str(x))
    # this creates x as a new label to the GUI
        label.pack() 

root = Tk()

button = Button(root, text="Print Me", command=printSomething) 
button.pack()

root.mainloop()

Answer 2

我认为你没有什么可以把你的 "Hey whatsup bro, i am doing something very interresting." 放进去。在 tkinter 中，你需要一个标签之类的东西来输出文本，或者你创建一个新的 def 并在那里定义按钮必须做什么，如果有人点击它.
