Class XMLGridLayout

java.lang.Object
  org.nuiton.widget.XMLGridLayout

All Implemented Interfaces:

LayoutManager

public class XMLGridLayout
extends Object
implements LayoutManager

XMLGridLayout uses a XML input (a string, for the time being) to define the layout of components inside the container. To do this a set of constraints in the form of GridBagConstraints are build and associated to a name. When adding the component to the container, the name of the constraint to be used must be supplied, using the add(name,component) method. If the name associated to the component has no associated constrain, the component is not layout.
Implementation Note: Internally this class uses a GridBagLayout and delegates to it all the calculations necesary to layout the components.
