Constructor Summary

ColorAtom(Atom atom, java.awt.Color bg, java.awt.Color c)
Creates a new ColorAtom that sets the given colors for the given atom.

ColorAtom(java.awt.Color bg, java.awt.Color c, ColorAtom old)
Creates a ColorAtom that overrides the colors of the given ColorAtom if the given colors are not null.

Method Summary

Box	createBox(TeXEnvironment env) Convert this atom into a Box, using properties set by "parent" atoms, like the TeX style, the last used font, color settings, ...
int	getLeftType() Get the type of the leftermost child atom.
int	getRightType() Get the type of the rightermost child atom.
void	setPreviousAtom(Dummy prev) Sets the given dummy containing the atom that comes just before the first child atom of this "composed atom".

ColorAtom

public ColorAtom(Atom atom,
                 java.awt.Color bg,
                 java.awt.Color c)

Creates a new ColorAtom that sets the given colors for the given atom. Null for a color means: no specific color set for this atom.

Parameters:

atom - the atom for which the given colors have to be set

bg - the background color

c - the foreground color

ColorAtom

public ColorAtom(java.awt.Color bg,
                 java.awt.Color c,
                 ColorAtom old)

Creates a ColorAtom that overrides the colors of the given ColorAtom if the given colors are not null. If they're null, the old values are used.

Parameters:

bg - the background color

c - the foreground color

old - the ColorAtom for which the colorsettings should be overriden with the given colors.

Method Detail

createBox

public Box createBox(TeXEnvironment env)

Description copied from class: Atom

Convert this atom into a Box, using properties set by "parent" atoms, like the TeX style, the last used font, color settings, ...

Specified by:

createBox in class Atom

Parameters:

env - the current environment settings

Returns:

the resulting box.

getLeftType

public int getLeftType()

Description copied from class: Atom

Get the type of the leftermost child atom. Most atoms have no child atoms, so the "left type" and the "right type" are the same: the atom's type. This also is the default implementation. But Some atoms are composed of child atoms put one after another in a horizontal row. These atoms must override this method.

Overrides:

getLeftType in class Atom

Returns:

the type of the leftermost child atom

getRightType

public int getRightType()

Description copied from class: Atom

Get the type of the rightermost child atom. Most atoms have no child atoms, so the "left type" and the "right type" are the same: the atom's type. This also is the default implementation. But Some atoms are composed of child atoms put one after another in a horizontal row. These atoms must override this method.

Overrides:

getRightType in class Atom

Returns:

the type of the rightermost child atom

setPreviousAtom

public void setPreviousAtom(Dummy prev)

Description copied from interface: Row

Sets the given dummy containing the atom that comes just before the first child atom of this "composed atom". This method will allways be called by another composed atom, so this composed atom will be a child of it (nested). This is necessary to determine the glue to insert between the first child atom of this nested composed atom and the atom that the dummy contains.

Specified by:

setPreviousAtom in interface Row

Parameters:

prev - the dummy that comes just before this "composed atom"
