Method Details

linkTo

public void linkTo(FrameObject prior)

Link this frame to an existing frame. In the future this might do some ref count tricks.

Link this frame to an existing frame. This will never do any funny ref count tricks.

getLink

public FrameObject getLink()

Return the prior frame in the tree.

Close the frame actively. This frees any internal resources, frees this frame and frees the frame to which this is linked.
