Defines the requirements for an object that
represents a view for a model cell.
changeAttributes
public Map changeAttributes(GraphLayoutCache cache,
Map map)
Apply the specified map of attributes on the view.
childUpdated
public void childUpdated()
getAttributes
public AttributeMap getAttributes()
Returns all attributes of the view as a map.
getBounds
public Rectangle2D getBounds()
Returns the bounds for the view.
getCell
public Object getCell()
Returns the model object that this view represents.
getChildViews
public CellView[] getChildViews()
Returns the child views of this view.
getEditor
public GraphCellEditor getEditor()
Returns a cell editor for the view.
getParentView
public CellView getParentView()
Returns the parent of view of this view.
getPerimeterPoint
public Point2D getPerimeterPoint(EdgeView edge,
Point2D source,
Point2D p)
Returns the intersection of the bounding rectangle and the straight line
between the source and the specified point p. The specified point is
expected not to intersect the bounds. Note: You must override this method
if you use a different renderer. This is because this method relies on
the VertexRenderer interface, which can not be safely assumed for
subclassers.
getRendererComponent
public Component getRendererComponent(JGraph graph,
boolean selected,
boolean focus,
boolean preview)
Returns a renderer component, configured for the view.
intersects
public boolean intersects(JGraph g,
Rectangle2D rect)
Returns true if the view intersects the given rectangle.
isLeaf
public boolean isLeaf()
Returns true if the view is a leaf.
refresh
public void refresh(GraphLayoutCache cache,
CellMapper mapper,
boolean createDependentViews)
Refresh this view based on the model cell. This is
messaged when the model cell has changed.
removeFromParent
public void removeFromParent()
Removes this view from the list of childs of the parent.
update
public void update(GraphLayoutCache cache)
Update this view's attributes. This is messaged whenever refresh is
messaged, and additionally when the context of the cell has changed,
and during live-preview changes to the view.
