Constructor Detail

wtGraphVertex

wtGraphVertex(<wtCanvas|wtGraph> parentContainer, <wtWidget> peerWidget)

Constructs a G=(V,E) graph vertex from a wtWidget.

Parameters:
parentContainer - The parent container of this vertex.
peerWidget - The widget to be associated with this graph vertex.

addAnchorPoint

void addAnchorPoint(<wt2DPoint> point)

Adds an anchor point around this vertex. The coordinate for anchor points are relative to the top-left corner of the peer widget.

Parameters:
point - New anchor point for connecting to edges.

clearAnchorPoints

void clearAnchorPoints()

Clears all the anchor points of this vertex.

generateAnchorPoints

void generateAnchorPoints()

Generates the anchor points around the peer widget for connecting to edges.

getAbsolutePosition

wt2DPoint getAbsolutePosition()

Tells the top-left corner position of the peer widget relative to its parent container.

Returns:
Top-left corner position of peer widget.

getAnchorPoints

Array getAnchorPoints()

Tells all the current anchor points associated with this vertex.

Returns:
Anchor point array.

getCenterPoint

wt2DPoint getCenterPoint()

Tells the center point of the peer widget relative to its parent container.

Returns:
Center point coordinate of peer widget.

getClosestAnchorPoint

wt2DPoint getClosestAnchorPoint(point)

Tells the closest anchor point to a specified point in the parent container's coordinate system.

Returns:
Closest anchor point in parent container's coordinate system.

getEdgesFromVertex

Array getEdgesFromVertex(vertex)

Tells the incoming edges from a specific vertex.

Returns:
Incoming edge array.

getEdgesToVertex

Array getEdgesToVertex(vertex)

Tells the outgoing edges to a specific vertex.

Returns:
Outgoing edge array.

getInEdges

Array getInEdges()

Tells the incoming edges to this vertex in an array.

Returns:
Incoming edges to this vertex.

getInVertices

Array getInVertices()

Tells the vertices connected to this vertex via incoming edges.

Returns:
Vertices array.

getOutEdges

Array getOutEdges()

Tells the outgoing edges from this vertex in an array.

Returns:
Outgoing edges from this vertex.

getOutVertices

Array getOutVertices()

Tells the vertices connected to this vertex via outgoing edges.

Returns:
Vertices array.

getPeerWidget

wtWidget getPeerWidget()

Tells the peer widget associated with this vertex.

Returns:
Peer widget.

removeAnchorPoint

Object removeAnchorPoint(<Integer> idx)

Removes one of the anchor points from the anchor point array.

Parameters:
idx - Array index of the anchor point to be removed.

removeSelf

void removeSelf()

Removes this vertex, the associated peer widget, and all edges connected to and from this vertex.
