Description
The CScrollBar class provides the functionality of a Windows scroll-bar
control.
You create a scroll-bar control in two steps. First, call the
constructor CScrollBar to construct the CScrollBar object, then call the
◄Create► member function to create the scroll-bar control and attach it
to the CScrollBar object.
If you create a CScrollBar object within a dialog box (through a dialog
resource), the CScrollBar is automatically destroyed when the user
closes the dialog box.
If you create a CScrollBar object within a window, you may also need to
destroy it. If you create the CScrollBar object on the stack, it is
destroyed automatically. If you create the CScrollBar object on the heap
by using the new function, you must call delete on the object to destroy
it when the user terminates the Windows scroll bar.
If you allocate any memory in the CScrollBar object, override the
CScrollBar destructor to dispose of the allocations.
