Attributes

Methods

Return the accessible object at the specified row and column in the table. If both row and column index are valid then the corresponding accessible object is returned that represents the requested cell regardless of whether the cell is currently visible (on the screen).

nsIAccessible getCellAt(
  in long rowIndex,
  in long columnIndex
);

Parameters

rowIndex

The row index of the cell.

columnIndex

The column index of the cell.

Return value

An nsIAccessible object.

Translate the given row and column indices into the corresponding cell index.

long getCellIndexAt(
  in long rowIndex,
  in long columnIndex
);

Parameters

rowIndex

The row index of the cell.

columnIndex

The column index of the cell.

Return value

A cell index.

getColumnDescription()

Return the description text of the specified column in the table.

AString getColumnDescription(
  in long columnIndex
);

Parameters

columnIndex

The column index.

Return value

The column description.

getColumnExtentAt()

Return the number of columns occupied by the accessible cell at the specified row and column in the table. The result differs from 1 if the specified cell spans multiple columns.

long getColumnExtentAt(
  in long row,
  in long column
);

Parameters

row

The row index of the cell.

column

The column index of the cell.

Return value

The number of columns the cell spans.

Return the index of the column containg the given cell index.

long getColumnIndexAt(
  in long cellIndex
);

Parameters

cellIndex

The cell index.

Return value

The column index.

getRowAndColumnIndicesAt()

Translate the given cell index into the corresponding row and column indices.

void getRowAndColumnIndicesAt(
  in long cellIndex,
  out long rowIndex,
  out long columnIndex
);

getRowDescription()

Return the description text of the specified row in the table.

AString getRowDescription(
  in long rowIndex
);

Parameters

rowIndex

The row index.

Return value

The row description

getRowExtentAt()

Return the number of rows occupied by the accessible cell at the specified row and column in the table. The result differs from 1 if the specified cell spans multiple rows.

Return value

The number of rows the cell spans.

Return the index of the row containg the given cell index.

long getRowIndexAt(
  in long cellIndex
);

Parameters

cellIndex
