# Python - Tkinter pack() Method

This geometry manager organizes widgets in blocks before placing them in the parent widget.

## Syntax:

    widget.pack( pack_options )

Here is the list of possible options:

- expand: When set to true, widget expands to fill any space not otherwise used in widget's parent.

- fill: Determines whether widget fills any extra space allocated to it by the packer, or keeps its own minimal dimensions: NONE (default), X (fill only horizontally), Y (fill only vertically), or BOTH (fill both horizontally and vertically).

- side: Determines which side of the parent widget packs against: TOP (default), BOTTOM, LEFT, or RIGHT.

## Example:

Try following example by moving cursor on different buttons:

    from Tkinter import *

    root = Tk()
    frame = Frame(root)
    frame.pack()

    bottomframe = Frame(root)
    bottomframe.pack( side = BOTTOM )

    redbutton = Button(frame, text="Red", fg="red")
    redbutton.pack( side = LEFT)

    greenbutton = Button(frame, text="Brown", fg="brown")
    greenbutton.pack( side = LEFT )

    bluebutton = Button(frame, text="Blue", fg="blue")
    bluebutton.pack( side = LEFT )

    blackbutton = Button(bottomframe, text="Black", fg="black")
    blackbutton.pack( side = BOTTOM)

    root.mainloop()
