Tkinter Label 中心文本设置文本从左上角开始

Question

I'm creating a GUI for my application with Tkinter, and when I create a Label, the text is always at the center of the label, is there a way to set the text to start from the top left?

big_text_area = Label(self.master, text='Hello, World!', width=70, height=25, bg='white', foreground='black')
big_text_area.place(x=380, y=30)

I believe the position of your label is determined by the .place() function. So if you want the label to be at the top left, you should do:

big_text_area.place(x = 0, y = 0)

Tutorialspoint and effbot have a documentation for the .place( ) function and the arguments it takes. Most have default values so keep that in mind.

Another thing I would point out is that the width and height keyword arguments do not change the size of your text. Rather, they change the rectangular box around your text. This might be the reason why your text is still in the middle even if you set its positions to the top left. effbot again has the details on the Label widget.

Just a quick working example: (Python 3.7)

from tkinter import *

master = Tk()

master.geometry("200x200") 

# to change text size, use font=("font name", size)
w = Label(master, text="Hello, world!", font=("Helvetica", 22))

# explicitly set the text to be at the top left corner
w.place(anchor = NW, x = 0, y = 0)

mainloop()
