class PASCALIMPLEMENTATION TScrollingWinControl : public Vcl::Controls::TWinControl
TScrollingWinControl is the base class for controls that support scrolling.
Use TScrollingWinControl as a base class when defining a custom windowed control that supports scrolling.
Typically, a scrolling windowed control has horizontal and vertical scroll bars and scrolls a child control into view when the child control receives focus.
Examples of scrolling windowed controls include TForm and TScrollBox objects.
The scrolling window's BiDiMode determines whether the left or right side of the window's contents are displayed by default. The BiDiMode does not affect the window's coordinate system. The scroll bars must be adjusted programmatically according to the system locale.
