使用Tkinter在Python中放置按钮有任何帮助吗？

Question

UPDATE - I got it to work by using the .grid() function in Tkinter. Thanks for all the help!

I would like to make a button that will center itself in the middle of the GUI in Tkinter, but I have tried using the place() function and also, the pack() function will not work. Any tips or advice?

A section of my code:

restart = Button(tk, text = "Restart", command = restartGame)
    restart.pack()
    #The code to place the button in the middle goes here

Answer 1

I rarely ever recommend using place , but if you literally only have a single widget that you want to put in the center of some other widget, place is a really good choice:

restart.place(relx=.5, rely=.5, anchor="center")

relx sets the relative x coordinate to be the middle (it is a floating point value between 0.0 and 1.0)

rely sets the relative y coordinate to be the middle

anchor specifies that the center of the widget should be at the x/y coordinate

Answer 2

I assume you mean centering the button at the middle of the top/bottom.

You can use .pack(side = "bottom") to place the button at the bottom (middle) of the Tk window.

Using side = , you can define it as top, bottom, left, or right.

So this means that your code would look like:

restart = Button(tk, text = "Restart", command = restartGame)
restart.pack(side = "bottom")
