Constructor Detail

IAVertexRenderer

public IAVertexRenderer()

Constructs a renderer that may be used to render vertices.

Method Detail

getRendererComponent

public java.awt.Component getRendererComponent(com.jgraph.JGraph graph,
                                               com.jgraph.graph.CellView view,
                                               boolean sel,
                                               boolean focus,
                                               boolean preview)

Configure and return the renderer based on the passed in components. The value is typically set from messaging the graph with convertValueToString. We recommend you check the value's class and throw an illegal argument exception if it's not correct.

Specified by:

getRendererComponent in interface com.jgraph.graph.CellViewRenderer

Parameters:

graph - the graph that that defines the rendering context.

value - the object that should be rendered.

selected - whether the object is selected.

hasFocus - whether the object has the focus.

isPreview - whether we are drawing a preview.

Returns:

the component used to render the value.

installAttributes

protected void installAttributes(com.jgraph.graph.CellView view)

Install the attributes of specified cell in this renderer instance. This means, retrieve every published key from the cells hashtable and set global variables or superclass properties accordingly.

Parameters:

cell - to retrieve the attribute values from.

paint

public void paint(java.awt.Graphics g)

Paint the renderer. Overrides superclass paint to add specific painting.

Overrides:

paint in class javax.swing.JComponent

paintComponent

protected void paintComponent(java.awt.Graphics g)

Overrides:

paintComponent in class javax.swing.JComponent

supportsAttribute

public boolean supportsAttribute(java.lang.Object key)

Returns true if key is a supported attribute in the renderer. Supported attributes affect the visual appearance of the renderer.

Specified by:

supportsAttribute in interface com.jgraph.graph.CellViewRenderer

Parameters:

key - the key that defines the attribute to be checked.

Returns:

true if key is supported by this renderer.
