UserBuiltNodeView	handleActionPerformed(int xCoord, int yCoord) Handles the actionPerformed event.
NodeView	isOnChildLinks(int x, int y) Checks if any mouse event (given by the coordinates passed as arguments) occurred inside any of this node view's child links.

Constructor Detail

UserBuiltNodeView

public UserBuiltNodeView(UserBuiltNodeView parent,
                         UserBuiltNodeModel nodeModel)

Creates a UserBuiltNodeView object using the parent node view and the corresponding model as arguments.

Parameters:

parent - this node view's parent

nodeModel - the model representing this node view

Method Detail

handleActionPerformed

public UserBuiltNodeView handleActionPerformed(int xCoord,
                                               int yCoord)

Handles the actionPerformed event.

Parameters:

xCoord - the x-coordinate of the last mousePressed event

yCoord - the y-coordinate of the last mousePressed event

Returns:

the node view the removed link used to connect to this node

getOverlappedNode

public UserBuiltNodeView getOverlappedNode(int xCoord,
                                           int yCoord,
                                           UserBuiltNodeView nodeView)

Returns the node that is overlapped by the node passed as argument.

Parameters:

xCoord - the x-coordinate of the mouse event

yCoord - the y-coordinate of the mouse event

nodeView - the node that may overlap this node

Returns:

the node that is overlapped by the node passed as argument

isOnChildLinks

public NodeView isOnChildLinks(int x,
                               int y)

Checks if any mouse event (given by the coordinates passed as arguments) occurred inside any of this node view's child links.

Overrides:

isOnChildLinks in class NodeView

Parameters:

x - the x-coordinate of the mouse event

y - the y-coordinate of the mouse event

Returns:

the target node view of the pressed link

addChildLink

public void addChildLink(UserBuiltLinkView childLink)

Adds a child link view to this node's vector of child links.

Parameters:

childLink - the link view to be added to this node's vector of child links

addChildIfOverlap

public boolean addChildIfOverlap(int xCoord,
                                 int yCoord,
                                 UserBuiltNodeView newChild)

Adss the node passed as argument to the current node's vector of child node views if the two nodes overlap.

Parameters:

xCoord - the x-coordinate of the mouse event

yCoord - the y-coordinate of the mouse event

newChild - the node to compare with the current node

Returns:

true if the two nodes overlap
