OnSelectionChanged Method of the ITextValidatorEvents Interface
This method is implemented on the client-side. It is called by ABBYY FineReader Engine after text selection has been changed in the Text Validator.
It delivers to the client the cursor position of the beginning of the selection and the length of the selection.
HRESULT OnSelectionChanged( IEditorPosition* Position, int Length );
void OnSelectionChanged( IEditorPosition Position, int Length );
Visual Basic .NET
Sub OnSelectionChanged( _ Position As IEditorPosition, _ Length As Integer _ )
- [in] Refers to the EditorPosition object that contains the cursor position of the beginning of the selection.
- [in] Specifies the length of the selection.
This method has no specific return values. It returns the standard return values of ABBYY FineReader Engine functions.
The client implementation of this method must assure that all exceptions thrown inside the method are caught and handled and no exceptions are propagated outside the method. Propagation of an exception outside the method may lead to unpredictable results (such as program termination).
