# class Row(Frame)

A Row is a container that lays out a collection of components in a horizontal row.
The initial size of the container is made just big enough to hold its contents. The vertical alignment of items within the row may be specified, and one item may optionally be designated to expand horizontally when the container is resized.
In addition, the width and/or height of all items may optionally be equalized before they are laid out.

## Constructor

Row(items, keyword = value, ...)
  Creates a Row containing the specified items, which should be a sequence of Components. The following keyword arguments may be used:

spacing = 10 | Horizontal space to leave between items.
padding = (0, 0) | Space to leave horizontally and vertically around all the items.
align = 'c' | Specifies vertical alignment and anchoring of items. One of 't', 'c', 'b' or 'tb' for top, centre, bottom or top-and-bottom.
equalize = '' | Specifies whether to make the size of all items equal in the horizontal and/or vertical direction. One of 'w', 'h' or 'wh'.
expand = None | Specifies which item, if any, is to change size horizontally when the container is resized. May be the item itself or an index into the item list. Items to the left of this item will be anchored to the left of the container, and items to the right will be anchored to the right of the container.
If specified by an index, the item at that index may be None to leave an expanding space in the row.
