Class GNodeSkin

java.lang.Object

de.tesis.dynaware.grapheditor.GNodeSkin

public abstract class GNodeSkin
extends java.lang.Object

The skin class for a GNode. Responsible for visualizing nodes in the graph editor.

A custom node skin must extend this class. It must also provide a constructor taking exactly one GNode parameter.

The node skin is responsible for adding its connectors to the scene graph and laying them out.

The root JavaFX node of this skin is a ResizableBox.

isSelected(), setSelected(boolean)

Constructor Detail

GNodeSkin

public GNodeSkin(de.tesis.dynaware.grapheditor.model.GNode node)

Creates a new GNodeSkin.

Parameters:

node - the GNode represented by the skin

Method Detail

getNode

public de.tesis.dynaware.grapheditor.model.GNode getNode()

Gets the node model element represented by the skin.

Returns:

the GNode represented by the skin

getRoot

public ResizableBox getRoot()

Gets the root JavaFX node of the skin.

Returns:

a ResizableBox containing the skin's root JavaFX node

setGraphEditor

public void setGraphEditor(GraphEditor graphEditor)

Sets the graph editor instance that this skin is a part of.

Parameters:

graphEditor - a GraphEditor instance

getGraphEditor

public GraphEditor getGraphEditor()

Gets the graph editor instance that this skin is a part of.

This is provided for advanced skin customisation purposes only. Use at your own risk.

Returns:

the GraphEditor instance that this skin is a part of

isSelected

public boolean isSelected()

Gets whether the node is selected or not.

Returns:

true if the node is selected, false if not

setSelected

public void setSelected(boolean isSelected)

Sets whether the node is selected or not.

Parameters:

isSelected - true if the node is selected, false if not

selectedProperty

public javafx.beans.property.BooleanProperty selectedProperty()

The property that determines whether the node is selected or not.

See Also:

isSelected(), setSelected(boolean)

initialize

public void initialize()

Initializes the node skin.

The skin's layout values, e.g. its x and y position, are loaded from the GNode at this point.

setConnectorSkins

public abstract void setConnectorSkins(java.util.List<GConnectorSkin> connectorSkins)

Sets the node's connector skins.

This will be called as the node is created, or if a connector is added or removed. The connector skin's regions should be added to the scene graph.

Parameters:

connectorSkins - a list of GConnectorSkin objects for each of the node's connectors

layoutConnectors

public abstract void layoutConnectors()

Lays out the node's connectors.

getConnectorPosition

public abstract javafx.geometry.Point2D getConnectorPosition(GConnectorSkin connectorSkin)

Gets the position of the center of a connector relative to the node region.

This will be the point where a connection will attach to.

Parameters:

connectorSkin - a GConnectorSkin instance

Returns:

the x and y coordinates of the connector
