Call this function to create a Windows toolbar (a child window) and associate it with the CToolBar object.

virtual BOOL CreateEx(
   CWnd* pParentWnd,
   DWORD dwCtrlStyle = TBSTYLE_FLAT,
   DWORD dwStyle = WS_CHILD | WS_VISIBLE | CBRS_ALIGN_TOP,
   CRect rcBorders = CRect(
   0,
   0,
   0,
   0
),
   UINT nID = AFX_IDW_TOOLBAR
);

Параметры

pParentWnd
Pointer to the window that is the toolbar's parent.
dwCtrlStyle
Additional styles for the creation of the embedded CToolBarCtrl object. By default, this value is set to TBSTYLE_FLAT. For a complete list of toolbar styles, see dwStyle.
dwStyle
The toolbar style. See Toolbar Control and Button Styles in the Windows SDK for a list of appropriate styles.
rcBorders
A CRect object that defines the widths of the toolbar window borders. These borders are set to 0,0,0,0 by default, thereby resulting in a toolbar window with no borders.
nID
The toolbar's child-window ID.

Возвращаемое значение

Nonzero if successful; otherwise 0.

Заметки

It also sets the toolbar height to a default value.

Use CreateEx, instead of Create, when certain styles need to be present during the creation of the embedded tool bar control. For example, set dwCtrlStyle to TBSTYLE_FLAT | TBSTYLE_TRANSPARENT to create a toolbar that resembles the Internet Explorer 4 toolbars.
