Member Function Documentation

int GetCurSelection (   )  const [inline]

Returns the index of the currently selected child.

virtual void RenderChildren (   )  [protected, virtual]

Renders the currently selected child object. Reimplemented from Group. Reimplemented in AutoSwitch.

void Select (  int  n  )  [inline]

Selects which child to render. Selects the nth child as the child to render. It is acceptable for n to be greater than the number of objects in the Switch. In this case, nothing will be drawn with a call to Render() until an nth child is added to the switch.
