n the VCL, the TWinControl branch includes all controls that descend from TWinControl. TWinControl is the base class for all windowed controls, which are items that you will use in the user interface of an application, such as buttons, labels, and scroll bars. Windowed controls are wrappers around a Windows control.
In CLX, TWidgetControl, which replaces TWinControl, is the base class for all widget controls, which are wrappers around widgets.
Windowed and widget controls:
Can receive focus while an application is running, which means they can receive keyboard input from the application user. In comparison, other controls may only display data.
Can be a parent of one or more child controls.
Have a handle, or unique identifier.
The TWinControl/TWidgetControl branch includes both controls that are drawn automatically (including TEdit, TListBox, TComboBox, TPageControl, and so on) and custom controls that C++Builder must draw, such as TDBNavigator, TMediaPlayer (VCL only), and TGauge (VCL only). Direct descendants of TWinControl/TWidgetControl typically implement standard controls, like an edit field, a combo box, list box, or page control, and, therefore, already know how to paint themselves.
The TCustomControl class is provided for components that require a window handle but do not encapsulate a standard control that includes the ability to repaint itself. You never have to worry about how the controls render themselves or how they respond to events—C++Builder completely encapsulates this behavior for you.
