CListBox::Create

Creates the Windows list box and attaches it to the CListBox object.

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

dwStyle

Specifies the style of the list box. Apply any combination of list-box styles to the box.

rect

Specifies the list-box size and position. Can be either a CRect object or a RECT structure.

pParentWnd

Specifies the list box's parent window (usually a CDialog object). It must not be NULL.

nID

Specifies the list box's control ID.

Nonzero if successful; otherwise 0.

You construct a CListBox object in two steps. First, call the constructor and then call Create, which initializes the Windows list box and attaches it to the CListBox object.

When Create executes, Windows sends the WM_NCCREATE, WM_CREATE, WM_NCCALCSIZE, and WM_GETMINMAXINFO messages to the list-box control.

These messages are handled by default by the OnNcCreate, OnCreate, OnNcCalcSize, and OnGetMinMaxInfo member functions in the CWnd base class. To extend the default message handling, derive a class from CListBox, add a message map to the new class, and override the preceding message-handler member functions. Override OnCreate, for example, to perform needed initialization for a new class.

Apply the following window styles to a list-box control.

  • WS_CHILD   Always

  • WS_VISIBLE   Usually

  • WS_DISABLED   Rarely

  • WS_VSCROLL   To add a vertical scroll bar

  • WS_HSCROLL   To add a horizontal scroll bar

  • WS_GROUP   To group controls

  • WS_TABSTOP   To allow tabbing to this control


// pParentWnd is a pointer to the parent window.
m_myListBox.Create(WS_CHILD|WS_VISIBLE|LBS_STANDARD|WS_HSCROLL, 
   CRect(10,10,200,200), pParentWnd, IDC_MYLISTBOX);
