Interface | public interface IOrthogonalEdgeHelper |
Implementors | OrthogonalEdgeHelper |
OrthogonalEdgeEditingContext
and the like that can be decorated to the
ILookup
of IEdge
s.
This interface is for editing edges in such a way that their path stays orthogonal, i.e. all of the segments
are oriented either horizontally or vertically.

Method | Defined By | ||
---|---|---|---|
Determines whether this end of the provided edge can be moved in the input mode context. | IOrthogonalEdgeHelper | ||
Callback method that is invoked after the provided edge has been edited orthogonally. | IOrthogonalEdgeHelper | ||
Gets the declared orientation of the given segment at the provided edge. | IOrthogonalEdgeHelper | ||
Determines whether the provided edge should be edited orthogonally at all in the specified input mode context. | IOrthogonalEdgeHelper |
canBeMoved | () | method |
public function canBeMoved(inputModeContext:IInputModeContext, edge:IEdge, sourceSide:Boolean):Boolean
Determines whether this end of the provided edge can be moved in the input mode context. This information is required to determine whether an edge's first or last segment needs to be split or the adjacent edge end can be moved along with the other end of the segment.
Parameters
inputModeContext:IInputModeContext — The input mode context in which the segment is edited.
| |
edge:IEdge — The edge to inspect.
| |
sourceSide:Boolean — If set to true the source end of the edge is queried, otherwise the target end.
|
Boolean — true if the end of the edge can be moved for the specified input mode context; otherwise,
false , in which case the corresponding segment needs to be split to keep the segment orientation
orthogonal.
|
cleanUpEdge | () | method |
public function cleanUpEdge(inputModeContext:IInputModeContext, graph:IGraph, edge:IEdge):void
Callback method that is invoked after the provided edge has been edited orthogonally. This callback can be used to remove unused bends and finalize the orthogonal edge editing gesture.
Parameters
inputModeContext:IInputModeContext — The input mode context which edited the edge.
| |
graph:IGraph — The graph to use for modifying the edge instance.
| |
edge:IEdge — The edge to clean up the path.
|
getSegmentOrientation | () | method |
public function getSegmentOrientation(inputModeContext:IInputModeContext, edge:IEdge, segmentIndex:int):uint
Gets the declared orientation of the given segment at the provided edge. The orientation cannot always be inferred from the current geometry: If a segment has a zero length it is unclear what orientation it should have, also a segment could be accidentally orthogonally oriented, while in fact it is considered non orthogonal.
Parameters
inputModeContext:IInputModeContext — The input mode context in which the orientation is needed.
| |
edge:IEdge — The edge to inspect.
| |
segmentIndex:int — The index of the segment.
|
uint — The declared orientation of the segment.

isOrthogonallyEdited | () | method |
public function isOrthogonallyEdited(inputModeContext:IInputModeContext, edge:IEdge):Boolean
Determines whether the provided edge should be edited orthogonally at all in the specified input mode context.
If this method returns false
, the other methods will not be queried at all.
Parameters
inputModeContext:IInputModeContext — The input mode context in which the edge is about to be edited.
| |
edge:IEdge — The edge to inspect.
|
Boolean — true if the edge should be edited orthogonally in the specified input mode context;
otherwise false .
