我正在尝试在我的图像上显示文本,但我不能这样做,任何人都可以帮忙。

代码:

# 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。将图像和文本都传递给构造函数,并传入compoundasTkinter.CENTER以将文本重叠到图像上。此功能的文档位于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,您不应该混合使用包和网格。您应该选择其中之一。参考:http ://effbot.org/tkinterbook/grid.htm

PS以防万一您希望文本垂直高于图像,您可以使用与上面相同的代码,除了 set compound=Tkinter.BOTTOM
