ITextValidatorEvents Interface

ITextValidatorEvents interface in ABBYY FineReader Engine Visual Components on Windows — This is a callback interface that is used for reporting events from the TextValidator object to the listeners.

Visual Components are implemented in FRE for Windows.

This is a callback interface that is used for reporting events from the TextValidator object to the listeners. This interface is implemented on the client-side. See the detailed implementation advice for your development tool in Working with Connectable Objects.

This interface is derived from IInputEvents interface and inherits its methods. The mouse and keyboard input events of Text Validator are, in fact, events of Text Editor built into Text Validator. They are used to monitor user input in Text Validator and, if necessary, respond to it. Note that the input events of Text Validator which has been opened using the Check Spelling button of Text Editor, are translated to Text Editor (not to Text Validator).

An object receiving notifications through this interface’s methods may do the following inside the methods’ implementation:

• Report information on spell checking and cancel some editing operations.
• Process any system messages to help prevent the application from appearing unresponsive during long operations. This can be useful in applications with a user interface.
• Report information about mouse moving and clicking, key pressing, symbols selection.
