在对话框中添加toolbar和statusbar

主要运用RepositionBars()函数，对对话框中的控件进行布局，代码放在OnInitDialog()中：

BOOL C************::OnInitDialog()

{

	CModelessDialog::OnInitDialog();



	// Create status bar at the bottom of the dialog window

	if (m_statusBar.Create(this))

	{

		m_statusBar.SetIndicators(m_lpaIDStatusBar, m_cIDStatusBar);

		OnSetMessageString(AFX_IDS_IDLEMESSAGE);



		// Make a sunken or recessed border around the first pane

		m_statusBar.SetPaneInfo(0, m_statusBar.GetItemID(0),

			SBPS_STRETCH, NULL );

	}



	// Create toolbar at the top of the dialog window

	if (m_toolBar.Create(this))

	{

		m_toolBar.LoadBitmap(m_nIDBitmap);

		m_toolBar.SetButtons(m_lpaIDToolBar, m_cIDToolBar);

	}



	m_toolBar.SetBarStyle(m_toolBar.GetBarStyle() |

		CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC);



	// We need to resize the dialog to make room for control bars.

	// First, figure out how big the control bars are.

	CRect rcClientStart;

	CRect rcClientNow;

	GetClientRect(rcClientStart);

	//将重绘工具栏和状态栏后剩余的客户区空间放到rcClientNow中

	RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST,

				   0, reposQuery, rcClientNow);



	// Now move all the controls so they are in the same relative

	// position within the remaining client area as they would be

	// with no control bars.

	CPoint ptOffset(rcClientNow.left - rcClientStart.left,

					rcClientNow.top - rcClientStart.top);



	CRect  rcChild;

	CWnd* pwndChild = GetWindow(GW_CHILD);

	while (pwndChild)

	{

		pwndChild->GetWindowRect(rcChild);

		ScreenToClient(rcChild);

		rcChild.OffsetRect(ptOffset);

		pwndChild->MoveWindow(rcChild, FALSE);

		pwndChild = pwndChild->GetNextWindow();

	}



	// Adjust the dialog window dimensions

	CRect rcWindow;

	GetWindowRect(rcWindow);

	rcWindow.right += rcClientStart.Width() - rcClientNow.Width();

	rcWindow.bottom += rcClientStart.Height() - rcClientNow.Height();

	MoveWindow(rcWindow, FALSE);



	// And position the control bars

	RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);



	// Set the icon for this dialog.  The framework does this automatically

	//  when the application's main window is not a dialog

	SetIcon(m_hIcon, TRUE);         // Set big icon

	SetIcon(m_hIcon, FALSE);        // Set small icon



	// Finally, center the dialog on the screen

	CenterWindow();

	return TRUE;

}
