The system provides a number of public window classes that support menus, frame windows, control windows, and dialog windows. An application can create a window of a system-defined public window class by specifying one of the following class name constants in a call to WinCreateWindow:

Each system-defined public window class has a corresponding set of window styles that an application can use to customize a window of that class. For example, a window created with the WC_BUTTON class has styles that include BS_PUSHBUTTON and BS_CHECKBOX. Window styles enable you to customize aspects of a window's behavior and appearance. The application specifies the window styles in the WinCreateWindow function.
