Method Detail
-
getCell
java.lang.Object getCell()
Returns the model object that this view represents.
-
refresh
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.
-
update
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.- Parameters:
cache
- TODO
-
childUpdated
void childUpdated()
-
getParentView
CellView getParentView()
Returns the parent of view of this view.
-
getChildViews
CellView[] getChildViews()
Returns the child views of this view.
-
removeFromParent
void removeFromParent()
Removes this view from the list of childs of the parent.
-
isLeaf
boolean isLeaf()
Returns true if the view is a leaf.
-
getBounds
java.awt.geom.Rectangle2D getBounds()
Returns the bounds for the view.
-
intersects
boolean intersects(JGraph g, java.awt.geom.Rectangle2D rect)
Returns true if the view intersects the given rectangle.
-
getPerimeterPoint
java.awt.geom.Point2D getPerimeterPoint(EdgeView edge, java.awt.geom.Point2D source, java.awt.geom.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.
-
changeAttributes
java.util.Map changeAttributes(GraphLayoutCache cache, java.util.Map map)
Apply the specified map of attributes on the view.
-
getAttributes
AttributeMap getAttributes()
Returns all attributes of the view as a map.
-
getAllAttributes
AttributeMap getAllAttributes()
-
getRendererComponent
java.awt.Component getRendererComponent(JGraph graph, boolean selected, boolean focus, boolean preview)
Returns a renderer component, configured for the view.
-
getHandle
CellHandle getHandle(GraphContext context)
Returns a cell handle for the view.
-
getEditor
GraphCellEditor getEditor()
Returns a cell editor for the view.
