Description Alec Beaton 2004-02-01 06:25:15 UTC 
Hi

In Tools->Options->International (OfficeXP) or View (Earlier Office versions)
There is an option to view current sheet right to left.
It means that columns will be shown : ..DBCA instead of the usual ABCD..
When I recorded the action as a Macro I got the following :

Sub Macro1()
'
' Macro1 Macro
' Macro recorded 01/02/2004 by Administrator
'
' Keyboard Shortcut: Ctrl+q
'
    ActiveSheet.DisplayRightToLeft = True
End Sub

Is there a way in HSSF to do it using HSSFSheet or something like that ?

Thanks.

IIRC, There is some stuff at the low level for this, but no high level API was
exposed.  I just recall seing it in the records and stuff.

Hi,

I looked into the files and found out that on WindowTwoRecord there is a method
called setArabic(boolean) which supposed to do the DisplayRightToLeft as it is 
described in excelfileformat.pdf (page 184) which is to set option's bit 6 
(0.0040H) to true or false.
Problem is : How can I reach from HSSFSheet the WindowTwoRecord ? I saw
that getSheet() is protected so I can't use the getRecordBySid method.

How can I reach the getSheet() method ? I see that you do it in HSSFWorkbook
so I don't know how it compiles as it is protected.

A future feature for next version might be to add a method  
setDisplayRightToLeft(boolean isRightToLeft) to HSSFSheet 
which does :

WindowTwoRecord windowTwo = (WindowTwoRecord) sheet.getSheet
().findFirstRecordBySid(WindowTwoRecord.sid);
windowTwo.setArabic(isRightToLeft);

Hi Some Additional Comments.

I understand you want me to enter a high level support of setDisplayRightToLeft 
to the CVS.
Since I have slow connection it will take me ages to download all the ANT+all 
BUILD and CVS files, and I do not know your policy regarding renaming a method. 
so I ask of you to do the following if you can :

1. Add a method in class HSSFSheet.java {
public void setDisplayRightToLeft(boolean isRightToLeft) {
   WindowTwoRecord windowTwo = (WindowTwoRecord) getSheet().findFirstRecordBySid
(WindowTwoRecord.sid);
   windowTwo.setArabic(isRightToLeft);
}

2. Maybe you can change the method name WindowTwoRecord::setArabic since it 
also applies to Hebrew. The method does setDisplayRightToLeft and I think 
should be called like that in WindowTwoRecord.

Thanks.

HSSFSHeet.setRightToLeft(boolean value) was added in POI 3.6.
