Package com.codename1.ui.layouts

Layout managers allow a Container to arrange its components by a set of rules that adapt to specific densities (ppi - pixels per inch).

Class Summary

Class	Description
BorderLayout	A border layout lays out a container, arranging and resizing its components to fit in five regions: north, south, east, west, and center.
BoxLayout	Layout manager that places elements in a row (X_AXIS) or column (Y_AXIS) according to box orientation.
CoordinateLayout	Deprecated the usage of this layout is strongly discouraged as elements will not adapt to the right position/size
FlowLayout	FlowLayout is the default layout manager for Codename One Containers and Forms.
GridBagConstraints	Port of the GridBag code from Apache's Harmony
GridBagLayout	Codename One port of the infamous GridBagLayout based on the Apache Harmony code.
GridLayout	The components are arranged in a grid based on available space, all cells in the grid are given exactly the same size which matches the largest preferred size or available space.
GroupLayout	GroupLayout is a LayoutManager that hierarchically groups components to achieve common, and not so common, layouts.
Insets	Port of Insets from Harmony for the use of the GridBag code
LayeredLayout	The LayeredLayout places the components in order one on top of the other and sizes them all to the size of the largest component.
Layout	Abstract class that can be used to arrange components in a container using a predefined algorithm.
LayoutStyle	LayoutStyle is used to determine how much space to place between components during layout.

Package com.codename1.ui.layouts Description

Layout managers allow a Container to arrange its components by a set of rules that adapt to specific densities (ppi - pixels per inch). A layout manager is an arranging algorithm encapsulated by an abstract class implementation that places components absolutely based on the "hints" received.

Layout Managers that ship with Codename One

FlowLayout is default layout manager, simple, flexible and with a few caveats.

BorderLayout is ubiquitous thru Codename One code.

BorderLayout can also behave differently based on the center behavior flag

BoxLayout Y axis is a the work-horse of component lists

BoxLayout X axis is a simpler replacement to flow layout and has grow/no grow variants.

GridLayout arranges elements in a grid where all elements have an equal size. It can auto adapt the column count.

TableLayout is similar in many regards to HTML tables. Notice that its in the com.codename1.ui.table package and not in this package.

LayeredLayout is unique in the sense that it is meant to costruct layers and not the UI positions. It only lays out on the Z axis.

GridBagLayout was added to Codename One to ease the porting of Swing/AWT applications.

MigLayout is a popular 3rd party layout manager its Codename One port is experimental.
