Action Item: Requirements for Table Support in a presentation

[Richard Schwerdtfeger <schwer@us.ibm.com>]

Ma Yue, Michael,

I had an action item to futher define requirements for what is needed for tables in presentations:

We must be able to:

• Determine what elements are row and column headers
• Determine what the row and column headers are for a table cell
• Determine the rows of the table and the table data cells
• We need to determine row and column header spans
• We need this in the spec. by June, or sooner, if companies are going to support these in products in time for 2007
• Get column/row descriptions
• Retrieve a table caption if available
• Retreive a table summary if availalble

This is a show stopper.

If you go to the url http://java.sun.com/j2se/1.4.2/docs/api/ and lookup javax.accessibility and find AccessibleTable. The markup must support the platform accessibility API when mapped by the .odp rendering application:

This interface has the following interface.

Accessible	getAccessibleAt(int r, int c)           Returns the Accessible at a specified row and column in the table.
Accessible	getAccessibleCaption()           Returns the caption for the table.
int	getAccessibleColumnCount()           Returns the number of columns in the table.
Accessible	getAccessibleColumnDescription(int c)           Returns the description text of the specified column in the table.
int	getAccessibleColumnExtentAt(int r, int c)           Returns the number of columns occupied by the Accessible at a specified row and column in the table.
AccessibleTable	getAccessibleColumnHeader()           Returns the column headers as an AccessibleTable.
int	getAccessibleRowCount()           Returns the number of rows in the table.
Accessible	getAccessibleRowDescription(int r)           Returns the description of the specified row in the table.
int	getAccessibleRowExtentAt(int r, int c)           Returns the number of rows occupied by the Accessible at a specified row and column in the table.
AccessibleTable	getAccessibleRowHeader()           Returns the row headers as an AccessibleTable.
Accessible	getAccessibleSummary()           Returns the summary description of the table.
int[]	getSelectedAccessibleColumns()           Returns the selected columns in a table.
int[]	getSelectedAccessibleRows()           Returns the selected rows in a table.
boolean	isAccessibleColumnSelected(int c)           Returns a boolean value indicating whether the specified column is selected.
boolean	isAccessibleRowSelected(int r)           Returns a boolean value indicating whether the specified row is selected.
boolean	isAccessibleSelected(int r, int c)           Returns a boolean value indicating whether the accessible at a specified row and column is selected.
void	setAccessibleCaption(Accessible a)           Sets the caption for the table.
void	setAccessibleColumnDescription(int c, Accessible a)           Sets the description text of the specified column in the table.
void	setAccessibleColumnHeader(AccessibleTable table)           Sets the column headers.
void	setAccessibleRowDescription(int r, Accessible a)           Sets the description text of the specified row of the table.
void	setAccessibleRowHeader(AccessibleTable table)           Sets the row headers.
void	setAccessibleSummary(Accessible a)           Sets the summary description of the table
