I know how to create a window of a given size. How do I control the placement of items like labels and text boxes in that window?

With the Tkinter GUI toolkit there a several ways to layout the position of the widgets. Here is an example of an absolute place layout ...
# set position and size of a Tkinter window
# also set the position of any widgets using place(x, y) layout
try:
# Python2
import Tkinter as tk
except ImportError:
# Python3
import tkinter as tk
# create the root window
root = tk.Tk()
# optionally give it a title
root.title("My Title")
# set the root window's height, width and x,y position
# x and y are the coordinates of the upper left corner
w = 300
h = 200
x = 50
y = 100
# use width x height + x_offset + y_offset (no spaces!)
root.geometry("%dx%d+%d+%d" % (w, h, x, y))
# use a colorful frame
frame = tk.Frame(root, bg='green')
frame.pack(fill='both', expand='yes')
# position a label on the frame using place(x, y)
# place(x=0, y=0) would be the upper left frame corner
label = tk.Label(frame, text="Hello Python Programmer!")
label.place(x=20, y=30)
# put the button below the label, change y coordinate
button = tk.Button(frame, text="Press me", bg='yellow')
button.place(x=20, y=60)
root.mainloop() DanWebb3148 0 Newbie Poster
This looks like it will be what I need. Let me try it out.

Sorry, I can't get your code to work in my program. I am trying to get an about box to look the way I want to. Here is my code. Can you move the two labels left and right of center. I would like to eventually have a icon picture to the right of the two labels and a list box below.

Experiment with side and expand parameters to pack and use help frames! You must assign frame first and pack it separately to use it for other widgets.
def showAbout():
t1 = Toplevel(root)
t1.geometry("430x300")
t1.title('About Lemniscate')
f = Frame(t1)
f.pack(side=LEFT, expand=False)
Label(f, text='Draw Lemniscate Curve', font=("Arial", 14)).pack(pady=30, side=TOP) # Can you get ride of the 'pack'?
Label(f, text='Programer: Dan Webb', font=("Arial", 14)).pack(side=TOP) DanWebb3148 0 Newbie Poster
Close, but I was hoping to place the Labels with something like 'label.place(x=5, y=30)'
