LayoutContainer

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.

Note

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

Abstract Value Members

  1. abstract def add(comp: Component, c: Constraints): Unit

    Adds a component with the given constraints to the underlying layout manager and the component peer.

    Adds a component with the given constraints to the underlying layout manager and the component peer. This method needs to interact properly with method constraintsFor, i.e., it might need to remove previously held components in order to maintain layout consistency. See BorderPanel for an example.

    Attributes
    protected
  2. abstract def areValid(c: Constraints): (Boolean, String)

    Checks whether the given constraints are valid.

    Checks whether the given constraints are valid. Additionally returns an error string that is only fetched if the constraints aren't valid.

    Attributes
    protected
  3. abstract def constraintsFor(c: Component): Constraints

    Obtains the constraints for the given component from the underlying Swing layout manager.

    Obtains the constraints for the given component from the underlying Swing layout manager.

  3. final def ##(): Int

    Equivalent to x.hashCode except for boxed numeric types.

    Equivalent to x.hashCode except for boxed numeric types. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them.

    returns

    a hash value consistent with ==

  7. final def asInstanceOf[T0]: T0

    Cast the receiver object to be of type T0.

    Cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

    returns

    the receiver object.

  17. final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    returns

    true if the argument is a reference to the receiver object; false otherwise.

    Called by the garbage collector on the receiver object when there are no more references to the object.

    The details of when and if the finalize method is invoked, as well as the interaction between finalize and non-local returns and exceptions, are all platform dependent.

    Test whether the dynamic type of the receiver object is T0.

    Test whether the dynamic type of the receiver object is T0.

    Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

    true if the receiver object is an instance of erasure of type T0; false otherwise.
