Table Accessibility
The Jade Platform supports accessibility and automation in tables, as follows.
-
Table cells expose "Cell (row, column)" as the value of the Name property and their content as the Value property.
-
Table cells expose their correct location within the table.
-
Table rows expose "Row (row)" as the value of the Name property and space‑delimited cell content as the Value property.
-
Table rows expose their correct location within the table.
-
Combo box list items (including spin box controls) expose the correct location.
-
Table row and cell selection resembles Jade selection logic, as follows.
-
If the value of the Table class selectMode property is SelectMode_CurrentRow or SelectMode_WholeRows, a change in row selection will result in the entire row gaining focus.
-
When a row has gained focus however, changing the column or clicking on the same cell will then cause that cell to gain focus, which allows for the selection of a single cell.
-
-
If a cell in a fixed column gains focus and the value of the Table class selectMode property is one of the following values, the entire row gains focus.
-
SelectMode_Default
-
SelectMode_FixedColumn
-
SelectMode_CurrentRow
-
SelectMode_WholeRows
-
It is recommended that if accessibility is to be advocated and remain able to be tested, Table, ComboBox, and ListBox controls that may contain over approximately 1,000 entries should be populated with the Collection class displayCollection method. This ensures that the initial accumulated cost of querying children is limited to the number of entries displayed.
External applications that utilize accessibility (such as the Windows Inspect tool) and call Jade's accessibility framework may result in an accessibility object being created for each child. This can have a negative impact on the performance of the external application.
