trait LayoutContainer
[source: scala/swing/LayoutContainer.scala]
trait LayoutContainer
extends Wrapper

A container that associates layout constraints of member type Constraints with its children. See GridBagPanel for an example container with custom constraints.

Notes
[Java Swing] In scala.swing, panels and layout managers are combined into subclasses of this base class. This approach allows for typed component constraints.
Direct Known Subclasses:
BorderPanel, GridBagPanel

Method Summary
protected abstract def add (comp : Component, c : Constraints) : Unit
Adds a component with the given constraints to the underlying layout manager and the component peer.
protected abstract def areValid (c : Constraints) : (Boolean, java.lang.String)
Checks whether the given constraints are valid. Additionally returns an error string that is only fetched if the constraints aren't valid.
protected abstract def constraintsFor (c : Component) : Constraints
Obtains the constraints for the given component from the underlying Swing layout manager.
def layout : Map[Component, Constraints]
A map of components to the associated layout constraints. Any element in this map is automatically added to the contents of this panel. Therefore, specifying the layout of a component via layout(myComponent) = myConstraints also ensures that myComponent is properly add to this container.
