The drawing of the scrollbar is done by this method
void DrawScrollBar(FormType * form,ScrollBarType *
ScrollBarPtr)
{
if((MainEndIndex - MainStartIndex) > 8)
{
ScrollBarPtr =
FrmGetObjectPtr(form,FrmGetObjectIndex(form,ScrollList));
SclSetScrollBar (ScrollBarPtr,0, 0, (MainEndIndex -
MainStartIndex)-9,9);
FrmShowObject(form,FrmGetObjectIndex(form,ScrollList));
}
else
{
FrmHideObject(form,FrmGetObjectIndex(form,ScrollList));
}
}
