tkinter canvas create_text size (python3)

问题

I understand that it is possible to get the size of text on a canvas:

t = canvas.create_text(x, y, text='Hello StackOverflow')
print(canvas.bbox(t))

but I want to decide where to draw the text based on its size, so I need to know the size before the text is drawn. How to do that?

回答1:

A possible solution is

tk.font.Font(size=9, family='Helvetica').measure('HelloStackoverflow')

回答2:

Use that line of code.

canvas.create_text(245,100, fill = 'red', font = "Times 20 italic bold", text = "Hello StackOverflow" )

Here 245,100 is the center of the text box.

fill = 'red' it is text color

font = "Times 20 italic bold" # text size is 20 pixel and it is italic font.
