OnActivePageChanged Method of the ITextEditorEvents Interface
This method is implemented on the client-side. It is called by ABBYY FineReader Engine, after the active page has been changed in Text Editor. The process is invoked in the following situations:
- the active page is changed via the graphical user interface of Text Editor or any synchronized component
- the active page is changed via the API of Text Editor, Component Synchronizer, or any synchronized component
- the active page has been deleted
The method delivers to the client a reference to the new active page.
HRESULT OnActivePageChanged( IFRPage* Page );
void OnActivePageChanged( IFRPage Page );
Visual Basic .NET
Sub OnActivePageChanged(Page As IFRPage)
- [in] Refers to the FRPage object which contains the new active page in the document. This parameter may be NULL, which means that there is no active page in the document (for example, if all the pages are deleted).
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).
