This function is used to scroll the widget to a particular x and y item offset in a widget. For most widgets, the concept of an abstract item collapses to 'pixel', but it is possible for an item to unify with a different unit of measurement, such as a character or a line.
- pif:[in] Pointer to the IWidget interface object.
- x:[in] The horizontal item position to which the widget should scroll.
- y:[in] The vertical item position to which the widget should scroll.
int IWidget_ScrollHV(IWidget* pif, int x, int y);
