我无法在我的tkinter图像上显示文字

Question

我试图在我的图像上显示文字,但我不能这样做,任何人都可以帮助请.

码:

# import Image and the graphics package Tkinter
import Tkinter
import Image, ImageTk

class simpleapp_tk(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()

    def initialize(self):
##    def create_widgets(self):
        # create welcome label
        label1 = Tkinter.Label(self, text = "Update User")
        label1.grid(row = 0, column = 1, columnspan = 2, sticky = 'W')

# open a SPIDER image and convert to byte format
im = Image.open('C:\Users\JOHN\Desktop\key.jpg')

root = Tkinter.Tk()  # A root window for displaying objects

 # Convert the Image object into a TkPhoto object
tkimage = ImageTk.PhotoImage(im)

Tkinter.Label(root, image=tkimage).pack() # Put it in the display window

root.mainloop() # Start the GUI

Label构造函数接受一个参数compound.通过构造两个图像和文本,并通过在compound作为Tkinter.CENTER重叠文本到图像.有关此功能的文档,请访问http://effbot.org/tkinterbook/label.htm

import Tkinter
import Image, ImageTk

# open a SPIDER image and convert to byte format    
im = Image.open(r'C:\Users\JOHN\Desktop\key.jpg')

root = Tkinter.Tk()  # A root window for displaying objects

# Convert the Image object into a TkPhoto object
tkimage = ImageTk.PhotoImage(im)

Tkinter.Label(root, image=tkimage, text="Update User", compound=Tkinter.CENTER).pack() # Put it in the display window

root.mainloop() # Start the GUI

另请注意,您不应该混合包和网格.你应该选择其中一个.参考:http://effbot.org/tkinterbook/grid.htm

PS,以防你想要文本垂直高于图像,你可以使用与上面相同的代码,除了set compound=Tkinter.BOTTOM.
