  getContext()

• setFrame

  public static void setFrame(java.awt.Frame f)

  Parameters:

  f - The container to be registered

• getContext

  public static java.awt.Container getContext()

  Deprecated. replaced by acquireFrame.
  Try to acquire exclusive access to a shared context previously registered with @link(#setFrame). If the frame is currently in use by someone else, the call will wait until the other owner is releases it.

  The container previously registered with setFrame. It will be returned in as clean a state as possible, with no children, and a new instance of @link(FlowLayout). null is returned if the call is interrupted.

• acquireFrame

  public static java.awt.Frame acquireFrame()
                                     throws java.lang.InterruptedException

  Try to acquire exclusive access to a shared context previously registered with @link(#setContext). If the context is currently in use by someone else, the call will wait until the other owner is releases it.

  Returns:

  The container previously registered with setContext. It will be returned in as clean a state as possible, with no children, and a new instance of @link(FlowLayout). If no frame has been registered, one has been created.

  Throws:

  java.lang.InterruptedException - if the thread is interrupted while waiting for the context to become available.

  releaseFrame(java.awt.Frame)

• restoreContext

  java.lang.IllegalStateException - if the argument is not the result of calling @link(#acquireFrame), or if it has already been released.

  java.lang.ClassCastException - if the container is not a frame.

• releaseFrame

  public static void releaseFrame(java.awt.Frame f)
