class tableCell

extends java.lang.Object

tableCell represents the contents of a single cell in the table. This class is responsible for the mechanics of word wrapping.

Field Summary

(package private) arlut.csd.JTable.tableAttr	attr An individual cell may have a special font and colors set..
(package private) arlut.csd.JTable.tableCol	col What column is this cell in? We use this not only to handle column-specific attributes, but also to get a reference to our baseTable when we need it for internal calculations.
(package private) int	currentWidth
(package private) java.lang.Object	data We may have a binary representation of the text displayed in this cell recorded for convenience.
(package private) static boolean	debug
(package private) int	lastOfficialWidth
(package private) int	nominalWidth
(package private) java.lang.String	origText The non-word-wrapped text for this cell
private int	rowSpan How many rows has this cell been wrapped across?
(package private) boolean	selected Remember whether we are selected or not.

Method Summary

private void	calcRowSpan()
void	clear() This method reinitializes the cell to its virgin state.
int	getCurrentWidth() This method returns the width of this cell at its widest point, after word wrapping has been performed.
java.lang.Object	getData() This method retrieves a piece of random attendant data held with this cell.
java.awt.Font	getFont() Return this cell's font
int	getJust() Return this cell's justification
java.awt.FontMetrics	getMetrics() Return the fontmetrics that apply to this cell.
int	getNominalWidth() This method returns the width that the cell's current text would have if not wrapped.
int	getRowSpan() This method returns the number of lines this cell desires to occupy.
java.lang.String	getText(int n) This method returns the nth row of this cell's text, where the first row is 0.
private boolean	isspace(char c)
void	refresh() This method refreshes the cell's measurements, and should be called after the fontmetrics for this cell have changed.
void	setData(java.lang.Object data) This method is used to record a piece of random attendant data with this cell.
void	setText(java.lang.String newText) This method sets the text for this cell.
void	wrap(int wrap_length) This method wraps the contained text to a certain number of pixels.

Method Detail

clear

public void clear()

This method reinitializes the cell to its virgin state.

setText

public void setText(java.lang.String newText)

This method sets the text for this cell.

setData

public final void setData(java.lang.Object data)

This method is used to record a piece of random attendant data with this cell. It is used by rowTable to facilitate type-specific sorting.

getData

public final java.lang.Object getData()

This method retrieves a piece of random attendant data held with this cell. It is used by rowTable to facilitate type-specific sorting.

refresh

public void refresh()

This method refreshes the cell's measurements, and should be called after the fontmetrics for this cell have changed.

getMetrics

public java.awt.FontMetrics getMetrics()

Return the fontmetrics that apply to this cell.

getFont

public java.awt.Font getFont()

Return this cell's font

getJust

public int getJust()

Return this cell's justification

getCurrentWidth

public int getCurrentWidth()

This method returns the width of this cell at its widest point, after word wrapping has been performed.

getNominalWidth

public int getNominalWidth()

This method returns the width that the cell's current text would have if not wrapped.

getText

public java.lang.String getText(int n)

This method returns the nth row of this cell's text, where the first row is 0.

wrap

public void wrap(int wrap_length)

This method wraps the contained text to a certain number of pixels.

Parameters:

wrap_length - The width of the cell to wrap to, in pixels
