CScrollBar::Create

Creates the Windows scroll bar and attaches it to the CScrollBar object.

virtual BOOL Create( 
   DWORD dwStyle, 
   const RECT& rect, 
   CWnd* pParentWnd, 
   UINT nID  
);

dwStyle

Specifies the scroll bar's style. Apply any combination of scroll-bar styles to the scroll bar.

rect

Specifies the scroll bar's size and position. Can be either a RECT structure or a CRect object.

pParentWnd

Specifies the scroll bar's parent window, usually a CDialog object. It must not be NULL.

nID

The scroll bar's control ID.

Nonzero if successful; otherwise 0.

You construct a CScrollBar object in two steps. First, call the constructor, which constructs the CScrollBar object; then call Create, which creates and initializes the associated Windows scroll bar and attaches it to the CScrollBar object.

Apply the following window styles to a scroll bar:

  • WS_CHILD   Always

  • WS_VISIBLE   Usually

  • WS_DISABLED   Rarely

  • WS_GROUP   To group controls

// Example 1: 
// Create a horizontal CScrollBar control as a child window of CMyDialog  
// class (a CDialog-derived class). The scroll bar is NOT visible until the 
// call ShowScrollBar() is made. m_ScrollBarHorz is of type CScrollBar class, 
// and it is a member variable in CMyDialog class.
VERIFY(m_ScrollBarHorz.Create(SBS_HORZ | SBS_TOPALIGN | WS_CHILD,
   CRect(5, 5, 100, 30), this, IDC_SCROLLBARCTRL));

m_ScrollBarHorz.ShowScrollBar();

// Example 2: 
// Create a vertical CScrollBar control as a child window of CMyDialog  
// class (a CDialog-derived class). m_ScrollBarVert is of type CScrollBar  
// class, and it is a member variable in CMyDialog class.
VERIFY(m_ScrollBarVert.Create(SBS_VERT | SBS_LEFTALIGN | WS_CHILD | 
   WS_VISIBLE, CRect(5, 30, 30, 130), this, IDC_SCROLLBARCTRL));
