Method Detail

getDefaultFont

public ColorFont getDefaultFont()

init

protected void init()

Convinience mthod to be used i anonymous subclasses.

createView

public CompositeView createView(AstStart start,
                                java.awt.Graphics g)

Creates view for variable or function name. '_' character indicates that subscript should be used for last part of expression.

Pendung:

whether we should use different fonts if expression has several levels of subscript?
