Cell and Cell Range Access
The interface com.sun.star.sheet.XSheetCellRange is derived from com.sun.star.table.XCellRange. It provides access to cells of the range and sub ranges, and is supported by the spreadsheet and sub-ranges of a spreadsheet. The methods in com.sun.star.sheet.XSheetCellRange are:
com::sun::star::table::XCell getCellByPosition( [in] long nColumn, [in] long nRow) com::sun::star::table::XCellRange getCellRangeByPosition( [in] long nLeft, [in] long nTop, [in] long nRight, [in] long nBottom) com::sun::star::table::XCellRange getCellRangeByName ( [in] string aRange) com::sun::star::sheet::XSpreadsheet getSpreadsheet()
The interface com.sun.star.table.XCellRange provides methods to access cell ranges and single cells from a cell range.
Cells are retrieved by their position. Cell addresses consist of a row index and a column index. The index is zero-based, that is, the index 0 means the first row or column of the table.
Cell ranges are retrieved:
- Addresses of cell ranges consist of indexes to the first and last row, and the first and last column. Range indexes are always zero-based, that is, the index 0 points to the first row or column of the table.
- It is possible to address a cell range over its name in A1:B2 notation as it would appear in the application.
|In a spreadsheet, "A1:B2", "$C$1:$D$2", or "E5" are valid ranges. Even user defined cell names, range names, or database range names can be used.|
XCellRange contains the method
getSpreadsheet() that returns the com.sun.star.sheet.XSpreadsheet interface of the spreadsheet which contains the cell range.
// --- First cell in a cell range. --- com.sun.star.table.XCell xCell = xCellRange.getCellByPosition(0, 0); // --- Spreadsheet that contains the cell range. --- com.sun.star.sheet.XSpreadsheet xSheet = xCellRange.getSpreadsheet();
There are no methods to modify the contents of all cells of a cell range. Access to cell range formatting is supported. Refer to the chapter Formatting for additional details.
In the following example,
xRange is an existing cell range (a com.sun.star.table.XCellRange interface):
com.sun.star.beans.XPropertySet xPropSet = null; com.sun.star.table.XCellRange xCellRange = null; // *** Accessing a CELL RANGE *** // Accessing a cell range over its position. xCellRange = xRange.getCellRangeByPosition(2, 0, 3, 1); // Change properties of the range. xPropSet = (com.sun.star.beans.XPropertySet) UnoRuntime.queryInterface(com.sun.star.beans.XPropertySet.class, xCellRange); xPropSet.setPropertyValue("CellBackColor", new Integer(0x8080FF)); // Accessing a cell range over its name. xCellRange = xRange.getCellRangeByName("C4:D5"); // Change properties of the range. xPropSet = (com.sun.star.beans.XPropertySet) UnoRuntime.queryInterface(com.sun.star.beans.XPropertySet.class, xCellRange); xPropSet.setPropertyValue("CellBackColor", new Integer(0xFFFF80));
