unpublished | interface XAccessibleTable |
Usage Restrictions not published Description Implement this interface to give access to a two-dimensional table. The XAccessibleTable interface is used to represent two-dimensional tables. This interface combines the two interfaces `javax.accessibility.AccessibleTable` and `javax.accessibility.AccessibleExtendedTable` of the Java Accessibility API (version 1.4). All XAccessible objects that represent cells or cell-clusters of a table have to be at the same time children of the table. This is necessary to be able to convert row and column indices into child indices and vice versa with the methods getAccessibleIndex, getAccessibleRow, and getAccessibleColumn. The range of valid coordinates for this interface are implementation dependent. However, that range includes at least the intervals from the from the first row or column with the index 0 up to the last (but not including) used row or column as returned by getAccessibleRowCount and getAccessibleColumnCount. In case of the Calc the current range of valid indices for retrieving data include the maximal table size--256 columns and 32000 rows--minus one. Since OOo 1.1.2

getAccessibleRowHeaders
XAccessibleTable
getAccessibleRowHeaders();

getSelectedAccessibleRows
sequence< long >
getSelectedAccessibleRows();
Description Returns a list of the indices of completely selected rows in a table. Returns The returned sequence contains indices of all completely selected rows in the table. This sequence is in ascending order. If no row is selected then the sequence is empty.
