Using ClassView

Home |  Overview |  How Do I |  Tutorial

ClassView shows all the C++ classes for which definitions are available, and the members of those classes. Double-click on a class icon (or click the + symbol beside the icon) to expand the class and display its members.

ClassView uses icons to represent classes, class members, and other items in the project. The following table shows the icons and their meanings:

Icon	Meaning
	Class
	Protected member function
	Private member function
	Public member function
	Protected member variable
	Private member variable
	Public member variable
	Interface
	Method (for a COM object)
	Property (for a COM object)
	Dialog

Visual C++ derives the contents of the ClassView pane using a dynamic parser that scans the source files included in the project workspace. When you type in a new class, variable, or member function, ClassView and WizardBar are now automatically updated without saving.

The relationships in ClassView are logical relationships, not physical relationships, according to the defined class structure. ClassView displays C++ classes for which definitions according to the ANSI standard are available, and the members of those classes. For example, the following code provides both a declaration and a definition for class MyClass, its constructor, and a function, MyFunc(). The class and its two member functions will appear in ClassView.

class MyClass
{
public:
   MyClass();
   void MyFunc(void);
};

For a member to appear in the ClassView list, it must be declared in a header file included in the project.

See Adding a Class for the implications of defining classes and members without the use of the Visual C++ New Class feature.

In ClassView, you can:

• Add a new class to the project.
  
  
• Add a new ATL object to the project (MFC or ATL).
  
  
• Add a new form to the project.
  
  
• Add member functions to the selected class.
  
  
• Delete a member function from the selected class.
  
  
• Add member variables to the selected class.
  
  
• Add a virtual function that overrides a virtual function in the base class.
  
  
• Add a message handler for the selected class.
  
  
• Add a new interface to an existing ATL object or control
  
  
• Add a connection point to an ATL object
  
  
• Add a method to an interface or non-MFC Dispinterface
  
  
• Go to the definition of a class or member.
  
  
• Go to the references to a class or member.
  
  
• Display derived class or base class graphs.
  
  
• Reuse a class by storing it in the Gallery for later use in other projects.
  
  
• Set a breakpoint on a member function.
  
  
• Group class members by access specifier or alphabetically.
  
  
• Add a method to a COM interface.
  
  
• Add a property to a COM interface.
  
  
• Add an event to an ActiveX control.
  
  
• Create new folders in the project workspace.
  
  
• View properties of classes and their members.
