Constructor Detail

StickyViewWrapper

protected StickyViewWrapper()

Empty constructor, for subclassing and cloning purposes.

StickyViewWrapper

public StickyViewWrapper(View v)

Wrap a view into a sticky wrapper.

Method Detail

getUnstickyBoundingPoints2DRef

protected Polygon2D getUnstickyBoundingPoints2DRef()

Get the unsticky bounds.

getBoundingPoints2DRef

public Polygon2D getBoundingPoints2DRef()

Get the sticky bounds. You can modify the reference, but it won't do any good, since we always update our bounds based on the wrapped-up view.

Overrides:

getBoundingPoints2DRef in class ViewWrapper

Following copied from interface: edu.berkeley.guir.lib.satin.view.View

Returns:

the polygon bounds.

getStickyTransform

protected abstract AffineTransform getStickyTransform(AffineTransform tx)

Get the transform that makes the view "sticky". One way of thinking about it is that the transform returned by this method "undoes" part of the absolute transform of the Graphical Object attached to this view. For example, Sticky Z would "undo" the zoom part of the absolute transform, while Sticky R would "undo" the rotation part of the absolute transform.

Don't call getBoundingPoints2DRef() or any other method that gets or uses the bounds in this method, as that will cause a mutually recursive call.

Parameters:

tx - is storage space.

render

public void render(SatinGraphics g)

Description copied from interface: View

Render this view. Use (0,0) as the top-left corner of this view. Any transformations that the attached GraphicalObject has will automatically be applied, so all you have to do is render the view normally.

Overrides:

render in class SemanticZoomViewWrapper

clone

protected StickyViewWrapper clone(StickyViewWrapper vw)
