public class WritableCellFormat
extends jxl.write.biff.CellXFRecord

A user specified cell format, which may be reused across many cells. The constructors takes parameters, such as font details and the numerical date formats, which specify to Excel how cells with this format should be displayed. Once a CellFormat has been added to a Cell which has been added to a sheet, then the CellFormat becomes immutable (to prevent unforeseen effects on other cells which share the same format). Attempts to call the various set... functions on a WritableCellFormat after this time will result in a runtime exception.

Constructor Detail

WritableCellFormat

public WritableCellFormat()
A default constructor, which uses the default font and format. This constructor should be used in conjunction with the more advanced two-phase methods setAlignment, setBorder etc.


WritableCellFormat

public WritableCellFormat(CellFormat format)
A public copy constructor which can be used for copy formats between different sheets


WritableCellFormat

public WritableCellFormat(jxl.biff.DisplayFormat format)
A constructor which specifies a date/number format for Cells which use this format object

Parameters:
format - the format

WritableCellFormat

public WritableCellFormat(WritableFont font)
A CellFormat which specifies the font for cells with this format

Parameters:
font - the font

WritableCellFormat

public WritableCellFormat(WritableFont font,
                          jxl.biff.DisplayFormat format)
A constructor which specifies the font and date/number format for cells which wish to use this format

Parameters:
font - the font
format - the date/number format
Method Detail

setAlignment

public void setAlignment(Alignment a)
                  throws WriteException
Sets the horizontal alignment for this format

Parameters:
a -
Throws:
WriteException

setBackground

public void setBackground(Colour c)
                   throws WriteException
Sets the background colour for this cell format

Parameters:
c -
Throws:
WriteException

setBackground

public void setBackground(Colour c,
                          Pattern p)
                   throws WriteException
Sets the background colour and pattern for this cell format

Parameters:
c - the colour
p - the pattern
Throws:
WriteException

setBorder

public void setBorder(Border b,
                      BorderLineStyle ls)
               throws WriteException
Sets the specified border for this format

Parameters:
b -
ls -
Throws:
WriteException

setLocked

public void setLocked(boolean l)
               throws WriteException
Sets whether or not this XF record locks the cell. For this to have any effect, the sheet containing cells with this format must also be locke3d

Parameters:
l - the locked flag
Throws:
WriteException

setOrientation

public void setOrientation(Orientation o)
                    throws WriteException
Sets the text orientation for this format

Parameters:
o -
Throws:
WriteException

setShrinkToFit

public void setShrinkToFit(boolean s)
                    throws WriteException
Sets the shrink to fit flag

Throws:
WriteException

setVerticalAlignment

public void setVerticalAlignment(VerticalAlignment va)
                          throws WriteException
Sets the vertical alignment for this format

Parameters:
va -
Throws:
WriteException

setWrap

public void setWrap(boolean w)
             throws WriteException
Sets the wrap indicator for this format. If the wrap is set to TRUE, then Excel will wrap data in cells with this format so that it fits within the cell boundaries

Parameters:
w -
Throws:
WriteException
