atspi-table — An interface used by containers whose data is arranged in a tabular form.

    ╰── AtspiTable

Known Implementations

AtspiTable is implemented by AtspiAccessible.

Description

An interface used by containers whose contained data is arranged in a tabular (i.e. row-column) form. Tables may resemble a two-dimensional grid, as in a spreadsheet, or may feature objects which span multiple rows and/or columns, but whose bounds are aligned on a row/column matrix. Objects within tables are children of the table object, and they may be referenced either via a child index or via a row/column pair. Table 'cells' may implement other interfaces, such as Text, Action, Image, and Component, and should do so as appropriate to their onscreen rresentation and/or behavior.
