Miscellaneous

data Size Source #

Widget growth policies. These policies communicate to layout algorithms how a widget uses space when being rendered. These policies influence rendering order and space allocation in the box layout algorithm.

Constructors

Fixed	Fixed widgets take up the same amount of space no matter how much they are given (non-greedy).
Greedy	Greedy widgets take up all the space they are given.
