Field Detail

textPane

public static JTextPane textPane

Holds the text pane to be used for rich text rendering.

isRichText

protected boolean isRichText

INSET

public static int INSET

Defines the default inset to render rich text.

userObject

protected Object userObject

Holds the user object of the current cell.

Constructor Detail

JGraphpadEdgeRenderer

public JGraphpadEdgeRenderer()

Method Detail

paintRichText

protected void paintRichText(Graphics g,
                             int x,
                             int y)

Utility method to paint the rich text content for rich text values. This implementation simulates rich text vertical alignment by translating the graphics before painting the textPane.

Parameters:

g - The graphics to paint the rich text content to.

paintLabel

protected void paintLabel(Graphics g,
                          String label,
                          Point2D p,
                          boolean mainLabel)

Paint the specified label for the current edgeview.

getLabelSize

public Dimension getLabelSize(org.jgraph.graph.EdgeView view,
                              String label)

Returns the label size of the specified view in the given graph.

setText

public void setText(String text)

Defines the single line of text this component will display. If the value of text is null or empty string, nothing is displayed.

The default value of this property is null.

This is a JavaBeans bound property.

See Also:

#setVerticalTextPosition, #setHorizontalTextPosition, #setIcon

installAttributes

public void installAttributes(org.jgraph.graph.CellView view)

Extends the parent's method to configure the renderer for displaying the specified view.

Parameters:

view - The view to configure the renderer for.

getVerticalAlignment

public int getVerticalAlignment(Map map)

getAngleTol

public static int getAngleTol()
