Command execution

TStandardCanvasView implements the following MToolHandler functions for executing tool command bindings. You should not need to override these functions. These functions take a TToolCommandBinding parameter and create a (TDocumentComponentToolCommandBinding instance that is adopted into the Document framework. See Chapter 7, "Commands, interactors, and cursor tools," for more information on the these functions.

  virtual void AdoptAndDo( TToolCommandBinding* );
  virtual void DoBegin( TToolCommandBinding& );
  virtual void DoIncrement( TToolCommandBinding& );
  virtual void AdoptAndDoEnd( TToolCommandBinding* );

Figure 13 shows the classes involved in the command binding.
