ITextEditorEvents Interface

This is a callback interface that is used for reporting events from the TextEditor 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 all its methods. Note that the mouse and keyboard 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 about scaling, symbols selection, text editing and cancel these operations.
  • Process any Windows messages, which is useful in applications having user interface, to avoid the effect that the application "is not responding" during long operations.
  • Report information about mouse moving and clicking, key pressing, scrolling.
