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

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

[sc-dev] How to access cell values in a cell range in Calc add-ins?
Hi, i have succeeded in adding a function to Calc and reading the input
figures on a Calc spreadsheet. I'm using the .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++){
...
}
}
but it even doesn't work
Great help if one can give me a hint.
Thanx in advance
