MFC状态栏鼠标坐标显示

[菜鸟级高手]

现在建立了一个单文档，在客户区建立了逻辑坐标，如何才能在状态栏显示鼠标的逻辑坐标

[Gloveing]

1.在CMainFrame类中加上：

static UINT indicators[] =
{
ID_SEPARATOR, // status line indicator //设置状态栏
ID_INDICATOR_CAPS,
ID_INDICATOR_NUM,
ID_INDICATOR_SCRL,
ID_INDICATOR_TIME,//增加一项状态栏
};
2.重载CZhuangtaiView::OnMouseMove消息

void CZhuangtaiView::OnMouseMove(UINT nFlags, CPoint point) 
{
	char buf[20] = {0};
	sprintf(buf,"%d,%d",point.x,point.y); 
	CStatusBar* pStatus;
    pStatus=(CStatusBar*)AfxGetApp()->m_pMainWnd->GetDescendantWindow(ID_VIEW_STATUS_BAR);  
    pStatus->CStatusBar::SetPaneText(4,buf,TRUE);
}

在客户区建立逻辑坐标怎么理解？？？
