Package swingtree.layout

Class MigAddConstraint

java.lang.Object
swingtree.layout.MigAddConstraint
All Implemented Interfaces:
AddConstraint
public final class MigAddConstraint extends Object implements AddConstraint
A wrapper for mig layout constraint string to avoid the inherent brittleness of strings... Instances of this are immutable collections of mig layout constraints which can be merged with other instances of this class through the and(MigAddConstraint) method, which is in essence a wither method.
Here how this class would typically be used in a swing-tree UI: 

  	import static swingtree.UI.*;

      public class MyView extends JPanel {
          public MyView() {
          	of(this).withLayout(FILL.and(GROW).and(WRAP(3)))
          	.add(LEFT, label("Name:") )
          	.add(GROW.and(SPAN), textField("name") )
          	.add(LEFT, label("Address:") )
          	.add(GROW.and(SPAN), textField("address") )
           }
      }
As you can see this class is not used directly, but rather in the form of static constants as part of the UI class. You can define your own component constraints as static constants in your own code by using the of(String...) method.

      public static MigAddConstraint of(String... layoutConstraints)
      Create a new CompAttr with the given layout constraints
      Parameters:
      layoutConstraints - the layout constraints
      Returns:
      a new CompAttr, which may represent a single component or a group of layout constraints

    • and

      public MigAddConstraint and(MigAddConstraint attr)
      Create a new MigAddConstraint with the provided MigAddConstraint merged with this one.
      Parameters:
      attr - the MigAddConstraint to merge with this one
      Returns:
      a new MigAddConstraint with the provided MigAddConstraint merged with this one

    • and

      public MigAddConstraint and(String... layoutConstraints)
      Create a new MigAddConstraint with the provided layout constraints merged with this one.
      Parameters:
      layoutConstraints - the string layout constraints to merge with this one
      Returns:
      a new MigAddConstraint with the provided layout constraints merged with this one

    • toConstraintForLayoutManager

      public Object toConstraintForLayoutManager()
      Description copied from interface: AddConstraint
      Supplies the actual Object that is used by a particular layout manager to apply the constraint to a component.
      Specified by:
      toConstraintForLayoutManager in interface AddConstraint
      Returns:
      The Object that is used by a particular layout manager to apply the constraint to a component.
