IAnchor interface (textstor.h)
The IAnchor interface is implemented by the TSF manager. Clients of Microsoft Active Accessibility use IAnchor anchor objects to delimit a range of text within a text stream.
The interface ID is IID_IAnchor.
Inheritance
The IAnchor interface inherits from the IUnknown interface. IAnchor also has these types of members:
Methods
The IAnchor interface has these methods.
| IAnchor::ClearChangeHistory The IAnchor::ClearChangeHistory method clears the anchor change history flags. |
| IAnchor::Clone The IAnchor::Clone method produces a new anchor object positioned at the same location, and with the same gravity, as the current anchor. |
| IAnchor::Compare The IAnchor::Compare method compares the relative position of two anchors within a text stream. |
| IAnchor::GetChangeHistory The IAnchor::GetChangeHistory method gets the history of deletions that have occurred immediately preceding or following the anchor. |
| IAnchor::GetGravity The IAnchor::GetGravity method retrieves the gravity of the anchor in an IAnchor object. |
| IAnchor::IsEqual The IAnchor::IsEqual method evaluates two anchors within a text stream and returns a Boolean value that specifies the equality or inequality of the anchor positions. |
| IAnchor::SetChangeHistoryMask This method has not been implemented. |
| IAnchor::SetGravity IAnchor::SetGravity method |
| IAnchor::Shift The IAnchor::Shift method shifts the anchor forward or backward within a text stream. |
