This interface should be implemented by accessible objects that allow an 2-dimensional or indexed viewports (e.g. by scrolling). For example lists or flickable views.
Member Function Documentation
[virtual noexcept] QAccessibleViewportInterface::~QAccessibleViewportInterface()
Destroys the QAccessibleViewportInterface.
[pure virtual] QSizeF QAccessibleViewportInterface::contentSize() const
Returns the total size of the content in absolute values. For non-indexed viewports this will return the absolute size of the underlying content, for indexed viewports the count of rows and columns is returned.
[pure virtual] bool QAccessibleViewportInterface::isIndexed() const
Returns true if the underlying content is indexed (e.g. a list of items).
[pure virtual] QPointF QAccessibleViewportInterface::position() const
Returns the current position within the viewport in normalized values.
See also setPosition().
[pure virtual] void QAccessibleViewportInterface::setPosition(const QPointF &position)
Sets the viewport's position to the given position defined in normalized values.
See also position().
[pure virtual] QSizeF QAccessibleViewportInterface::viewportSize() const
Returns the currently visible portion of the content in normalized values.
