For Java developers writing GUI layouts by hand that wants simplicity, power and automatic per platform fidelity, that are dissatisfied with the current layout managers in Swing and SWT, MiGLayout solves all your layout problems. Unlike JGoodies' FormLayout and Clearthought's TableLayout - MiGLayout solves all your layouts with equal ease in a way that is easy to change and maintain. You will understand how the layout will look like when looking at the code.
MiGLayout is the most versatile and flexible Swing and SWT Layout Manager for Java, yet it is very easy to learn and use. It is using String or API type-checked constraints to format the layout. MiGLayout can produce flowing, grid based, absolute (with links), grouped and docking layouts. You will never have to switch to another layout manager ever again! MiGLayout is created to be to manually coded layouts what Matisse/GroupLayout is to IDE supported visual layouts.
Java SwingBuilder is an implementation of a Java Builder geared towards building UI interfaces using Java Swing.
Details
The main class is org.javabuilders.swing.SwingBuilder. It loads the object definition from a YAML file that is in the same package and has the same base name as the calling Java class. So, if you're building org.test.MyFrame.java it will look for org.test.MyFrame.yaml for the object build file (similar to the convention the Apache Wicket web framework uses).
