public class ScalableRootEditPart extends SimpleRootEditPart implements LayerConstants, LayerManager
Layers.
The layers are added to LayeredPane or
ScalableLayeredPane. All layers are positioned by
StackLayouts, 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) |
|
| ├ | Scaled Feedback Layer | ||
| ├ | Printable Layers | ||
| ├ Connection Layer | |||
| └ Primary Layer | |||
| └ | Grid Layer | ||

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.protected void createLayers(LayeredPane layeredPane)

adapter types. Currently, these types include
AccessibleHandleProvider and AccessibleAnchorProvider.
