public interface PackAs
This interface is returned/used by the Packer layout manager. The methods are used to arrange the layout of components. The majority of these methods correspond directly to elements of the GridBagConstraints object and its use with the GridBagLayout layout manager. The purpose of this class is to make the use of these two objects simpler and less error prone by allowing the complete layout of an object to be specified in a single line of code, and to discourage the reuse of GridBagConstraint Objects which leads to subtle layout interactions.
Pay attention to the fact that fillx(), filly() and fillboth() change the weights of the respective axis. This is done to unify the expansion factors to equally distribute the components if you do not specify weight[xy] values. If you do not specify the weight[xy] values, they default to 1. Thus, you must always put the weight[xy]() after the fill[xy]() if you want something different than equal expansion.
When putting several buttons into a JPanel, you can use
...fillx().weightx(0) to make all of them the same width,
but keep the JPanel from being any wider than the widest button.
