Adding a Member Variable

|  Overview |  How Do I | 

You can add a member variable to a class using ClassView or ClassWizard.

• If you want to add a generic C++ member variable, you must use ClassView.

• If you want to add a member variable for data exchange and data validation, you must use ClassWizard. ClassWizard is specifically designed to take the relevant information and use it to insert elements in your source files at the appropriate locations. ClassView adds a plain variable declaration to the header file.

Note   WizardBar does not have the capability of adding a member variable.

1. In ClassView, select the class to which you want to add a variable.

2. With the mouse pointer over the selected class, right-click to display the shortcut menu, and click Add Member Variable.

3. In the Variable Type text box, type the Member Variable data type.

4. In the Variable Name text box, type the variable name.

5. Select an access specifier for the variable from the Access group of options.

6. Click OK.

This procedure adds a variable definition to the header file for the class.
