To place objects in the middle of a frame, we can use the place method. Let's take an example and see how it's done.
Steps −
Import the required libraries and create an instance of tkinter frame.
Set the size of the frame using win.geometry method.
Next, create a button and label it.
Set the position of the buttons using the place method by supplying the x and y coordinate values.
Place the center of the widget at a relative x and y position of 0.5 of button widget (relx=0.5, rely=0.5). Set the anchor at the center by supplying "anchor=CENTER"
Finally, run the mainloop of the application window.
Example
# Import the Tkinter library
from tkinter import *
from tkinter import ttk
# Create an instance of Tkinter frame
win = Tk()
# Define the geometry
win.geometry("750x350")
win.title("Main Window")
def toplevel_position():
print("The coordinates of Toplevel window are:", top.winfo_x(), top.winfo_y())
top = Toplevel(win, height=150, width=300)
top.title("This is the Toplevel Window")
top.attributes('-topmost', 'true')
button = ttk.Button(top, text="Get position", command=toplevel_position)
button.place(relx=0.5, rely=0.5, anchor=CENTER)
top.mainloop()Output
When you execute this code, it will show the following output window −
Now, click the "Get position" button and it will print the coordinates of the Toplevel window on the console.
The coordinates of Toplevel window are: 282 105
