Package com.codename1.ui.layouts

package com.codename1.ui.layouts

Layout managers allow a com.codename1.ui.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

com.codename1.ui.layouts.FlowLayout is default layout manager, simple, flexible and with a few caveats.

com.codename1.ui.layouts.BorderLayout is ubiquitous thru Codename One code.

com.codename1.ui.layouts.BorderLayout can also behave differently based on the center behavior flag

com.codename1.ui.layouts.BoxLayout Y axis is a the work-horse of component lists

com.codename1.ui.layouts.BoxLayout X axis is a simpler replacement to flow layout and has grow/no grow variants.

com.codename1.ui.layouts.GridLayout arranges elements in a grid where all elements have an equal size. It can auto adapt the column count.

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

com.codename1.ui.layouts.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.

com.codename1.ui.layouts.GridBagLayout was added to Codename One to ease the porting of Swing/AWT applications.

com.codename1.ui.layouts.mig.MigLayout is a popular 3rd party layout manager its Codename One port is experimental.
