Python in a Nutshell

Name

pack

Synopsis

                        w.pack(**pack_options)

Delegates geometry management to the packer. pack_options may include:

expand

When true, w expands to fill any space not otherwise used in w’s parent.

fill

Determines whether w 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 w packs against: TOP (default), BOTTOM, LEFT, or RIGHT. To avoid confusion, don’t mix different values for option side= in widgets that are children of the same container. When more than one child requests the same side (for example TOP), the rule is first come, first served: the first child packs at the top, the second child packs second from the top, and so on.
