Implementation of Controls

ObjectWindows provides two types of implementation for controls: those which encapsulate a Windows control (either a standard control, or a common control), and those which are implemented internally.

The TGauge control, for example, can use the Progress Bar common control, or an internal implementation (which has more options).

If a control encapsulates a Windows 95 control, and also provides an internal implementation, the internal implementation can be used to provide emulation of the Windows 95 control in Windows 16.
