org.eclipse.gef.editparts.ScalableRootEditPart
public class ScalableRootEditPart
A graphical root composed of regular Layers
.
The layers are added to LayeredPane
or
ScalableLayeredPane
. All layers are positioned by
StackLayout
s, which means that the diagrams
preferred size is the union of the preferred size of each layer, and all
layers will be positioned to fill the entire diagram.
IMPORTANTScalableRootEditPart uses a Viewport
as its
primary figure. It must be used with a
ScrollingGraphicalViewer
. The viewport gets
installed into that viewer's FigureCanvas
, which
provides native scrollbars for scrolling the viewport.
The layer structure (top-to-bottom) for this root is:
Root Layered Pane | |||
├ | Guide Layer | ||
├ | Feedback Layer | ||
├ | Handle Layer | ||
└ | Scalable Layers | (ScalableLayeredPane ) |

AbstractGraphicalEditPart.createFigure()
protected GridLayer createGridLayer()
grid
. Sub-classes can override this method to
customize the appearance of the grid. The grid layer should be the first
layer (i.e., beneath the primary layer) if it is not to cover up parts on
the primary layer. In that case, the primary layer should be transparent
so that the grid is visible.

AbstractEditPart.getAdapter(Class)
to handle additional
adapter types. Currently, these types include
AccessibleHandleProvider
and AccessibleAnchorProvider
.
Subclasses should extend this method to support additional
adapter types, or to replace the default provided adapaters.
