UnoRuntime.queryInterface(com.sun.star.sheet.XCellRangeAddressable.class,
xCellRange);

CellRangeAddress aRangeAddress = xRangeAddr.getRangeAddress();

 From aRangeAddress you can get details about range start column,start row
  and range end column,end row. Then you can get the no of columns and rows
you have in the range

int noOfColums = aRangeAddress.EndColumn - aRangeAddress.StartColumn + 1;
int noOfRows = aRangeAddress.EndRow - aRangeAddress.StartRow + 1;

Then traverse through the range using this and you can get all the cells
inside the given range.

for (int i = 0; i  noOfColums; i++) {

 for (int j = 0; j  noOfRows; j++) {

 XCell cell = xCellRange.getCellByPosition(i, j);

 }


Or if the parameter has a type like sequence sequence double   in 
IDL, which is double[][] in Java, you can just use length to access 
the array's length.

Hi Nadee,

You can use com.sun.star.sheet.XCellRangeAddressable interface and
CellRangeAddress.

com.sun.star.sheet.XCellRangeAddressable xRangeAddr =
(com.sun.star.sheet.XCellRangeAddressable)
UnoRuntime.queryInterface(com.sun.star.sheet.XCellRangeAddressable.class,
xCellRange);

CellRangeAddress aRangeAddress = xRangeAddr.getRangeAddress();

From aRangeAddress you can get details about range start column,start row
 and range end column,end row. Then you can get the no of columns and rows
you have in the range

int noOfColums = aRangeAddress.EndColumn - aRangeAddress.StartColumn + 1;
int noOfRows = aRangeAddress.EndRow - aRangeAddress.StartRow + 1;

Then traverse through the range using this and you can get all the cells
inside the given range.

for (int i = 0; i  noOfColums; i++) {

for (int j = 0; j  noOfRows; j++) {

XCell cell = xCellRange.getCellByPosition(i, j);

}

Hope this might help you

 Hi, i have succeeded in adding a function to Calc and reading the input
 figures on a Calc spreadsheet. I'm using the projectName.impl.java file
 generated and changing its return statement so as to give the result of my
 function.

 But I can only access a pre-defined number of cells only. i.e. the size of
 the array i define in the java code. How can I access a dynamically
 determined cell range and use its values to do a computation?? [image:
 Rolling Eyes]
 eg: when the user inputs the cell values as
 2 4 7
 1 7 3
 4 3 9
 each value in one cell, and when I program to take a 3*3 array(2-D array),
 computation succeeds(obvious) But I need to extend the code to be able to
 access any sized cell range.

 I've tried out the method of creating the for loop as
 for(int i=0; ; i++){
 for(int j=0; ; j++){
 ...mycode
 }
 }
 but it even doesn't work

 Great help if one can give me a hint.
 Thanx in advance
