[英]Python - Tkinter Label Output?
How would I take my entries from Tkinter, concatenate them, and display them in the Label below (next to 'Input Excepted: ')? 我如何从Tkinter获取我的条目,连接它们,并在下面的标签中显示它们(在“输入异常:”旁边)? I have only been able to display them input in the python console running behind the GUI.
我只能在GUI后面运行的python控制台中显示它们的输入。 Is there a way my InputExcept variable can be shown in the Label widget?
我的InputExcept变量是否可以在Label小部件中显示?
from Tkinter import *
master = Tk()
master.geometry('200x90')
master.title('Input Test')
def UserName():
usrE1 = usrE.get()
usrN2 = usrN.get()
InputExcept = usrE1 + " " + usrN2
print InputExcept
usrE = Entry(master, relief=SUNKEN)
usrE.pack()
usrN = Entry(master, relief=SUNKEN)
usrN.pack()
Btn1 = Button(text="Input", command=UserName)
Btn1.pack()
lbl = Label(text='Input Excepted: ')
lbl.pack()
master.mainloop()
Two main steps to do: 要做的两个主要步骤:
usrE
, usrE
and lbl
as global variables inside your callback method. usrE
, usrE
和lbl
声明为全局变量。 config()
method to update the text of lbl
. config()
方法来更新lbl
的文本。 Program: 程序:
Here is the solution: 这是解决方案:
from Tkinter import *
master = Tk()
master.geometry('200x90')
master.title('Input Test')
def UserName():
global usrE
global usrN
global lbl
usrE1 = usrE.get()
usrN2 = usrN.get()
InputExcept = usrE1 + " " + usrN2
print InputExcept
lbl.config(text='User expected:'+InputExcept)
usrE = Entry(master, relief=SUNKEN)
usrE.pack()
usrN = Entry(master, relief=SUNKEN)
usrN.pack()
Btn1 = Button(master, text="Input", command=UserName)
Btn1.pack()
lbl = Label(master)
lbl.pack()
master.mainloop()
Demo: 演示:
Running the program above will lead you to the expected result: 运行上面的程序将引导您达到预期的结果:
Note: 注意:
Do not forget to specify the parent widget ( master
) on which you draw the label and the button. 不要忘记指定绘制标签和按钮的父窗口小部件(
master
窗口)。
