Detailed Description

Application Framework text document view.

Library: ilvappframe

IlvDvTextView is a subclass of IlvText that implements the IlvDvDocViewInterface interface. It is used for displaying the text of the document in an IlvText gadget.
Classes that inherit from the IlvDvTextView class must be declared and implemented with specific macros, which allow instances of these classes to be created automatically by the document templates.
The following code sample shows how to derive from IlvDvTextView:

 class MyTextView
 : public IlvDvTextView * {
     IlvDvDeclareGadgetViewCreate();
 public:
     MyTextView(IlvDisplay* display) : IlvDvTextView(display) {}
     virtual void initializeView();
     ...
 };

 // Implementation file
 void
 MyTextView::initializeView()
 {
     IlvDvTextView::initializeView();
     // My initialization code here
 }
 ...
 IlvDvPreRegisterGadgetViewClass(MyTextView, IlvDvTextView);
 IL_BEGINMODULEINITDEF(mymodule)
     IlvDvPostRegisterDocIlvViewClass(MyTextView, IlvDvTextView);
 IL_ENDMODULEINITDEF(mymodule)

Member Function Documentation

virtual IlvGraphic* IlvDvTextView::getGraphic

(

)

[virtual]

Gets the graphic object of the document view.

Must be redefined by the class that implements the interface if the class inherits from the IlvGraphic class. In this case, the redefined method only returns this object. For example, the IlvDvTextView class redefines this method to return (IlvText*)this object. By default, the method returns 0.

Returns:

The graphic object of the document view.

Reimplemented from IlvDvDocViewInterface.

virtual void IlvDvTextView::initializeView

(

)

[virtual]

Initializes the text view.

Called by the document associated with the view to initialize its contents. By default, this method sends the generic message GetText to the document in order to retrieve the document text. If the document class inherits from the IlvDvTextDocument class, this message is processed automatically. Otherwise, the method defined for processing this generic message must return a const char* value. This is illustrated in the following code sample:

 IlvDvBeginInterface(MyTextDocument)
        TypedMethod(GetText, getText, const char*)
 IlvDvEndInterface1(IlvDvDocument)
 ...
 const char*
 MyTextDocument::getText() const
 {
        return _myText;
 }

Reimplemented from IlvDvDocViewInterface.
